Description

[0001] RNA MOLECULES CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Application No.63 / 678,289, filed on August 1, 2024, and to U.S. Provisional Application No.63 / 843,401, filed on July 14, 2025, the entire contents for both of which are herein incorporated by reference. REFERENCE TO SEQUENCE LISTING The instant application contains a sequence listing which has been submitted electronically in .xml format and is hereby incorporated by reference in its entirety. The .xml file, named “PC073127A Sequence Listing.xml”, was created on June 30, 2025, and is 1,058 KB in size. BACKGROUND Epstein Barr virus (EBV), also referred to as human herpesvirus 4, is a double- stranded DNA virus that infects B cells and epithelial cells and primarily spreads through body fluids and exchange of saliva in young children and adolescents. Ninety-five percent of the U.S. adult population is EBV-seropositive, with the likelihood of seroprevalence increasing with age. EBV is highly contagious and the cause of infectious mononucleosis (IM), which occurs most frequently in adolescence (17 to 19 years of age). IM is characterized by symptoms of fever, inflamed throat, swollen lymph nodes, enlarged spleen, fatigue and rash. Primary infection with EBV does not always produce clinical symptoms consistent with IM, and in young children (≤5 years of age), infection is usually asymptomatic. IM results from a primarily T cell-driven inflammatory response that damages tissues and causes swelling. Although the infection can be resolved in as little as two weeks, IM symptoms can last for 6 months up until one year. Following EBV infection (symptomatic or asymptomatic), the virus is maintained in a latent state in infected B cells, with periodic reactivation of lytic replication throughout the life of the human host. This period of latency has been linked to malignancies such as Burkitt's lymphoma, Hodgkin's and non-Hodgkin’s lymphoma, and nasopharyngeal carcinoma, and is thought to contribute to 1 to 2% of all tumors in humans. EBV latency has also been linked to the autoimmune disorder multiple sclerosis (MS). IM is associated with an increased risk of MS, especially in younger individuals. Currently, there is no licensed vaccine to prevent primary infection of EBV. Thus, there remains a need for vaccines for the prevention of disease associated with EBV infection. SUMMARY The present disclosure provides immunogenic compositions and methods for treating a subject comprising the administration of RNA molecules, e.g., an immunogenic RNA polynucleotide encoding an amino acid sequence, e.g., an immunogenic antigen, comprising an EBV protein, an immunogenic variant thereof, or an immunogenic fragment of the EBV protein or the immunogenic variant thereof, e.g., an antigenic peptide or protein. Thus, the immunogenic antigen comprises an epitope of an EBV protein for inducing an immune response against EBV in the subject. RNA polynucleotide encoding an immunogenic antigen is administered to provide (following expression of the polynucleotide by appropriate target cells) antigen for induction, e.g., stimulation, priming, and / or expansion, of an immune response, e.g., antibodies and / or immune effector cells. In one aspect, the immune response to be induced according to the present disclosure is a B cell-mediated immune response, e.g., an antibody-mediated immune response. Additionally or alternatively, the immune response to be induced according to the present disclosure may be a T cell-mediated immune response. In one aspect, the immune response is an anti-EBV immune response.

EXAMPLES OF DEFINITIONS Throughout this application, the terms “about” and “approximately” and “substantially” are used according to their plain and ordinary meaning in the area of cell and molecular biology to indicate a deviation of ±10% of the value(s) to which it is attached. Therefore, in any disclosed aspect, the terms may be substituted with “within [a percentage] of” what is specified. In one non-limiting aspect, the percentage includes 0.1, 0.5, 1, 5, and 10 percent. Recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it was individually recited herein. The use of the word “a” or “an” when used in conjunction with the terms “comprising,” “including,” “having,” or “containing,” or variations of these terms, may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” The phrase “and / or” means “and” or “or.” To illustrate, A, B, and / or C includes: A alone, B alone, C alone, a combination of A and B, a combination of A and C, a combination of B and C, or a combination of A, B, and C. In other words, “and / or” operates as an inclusive or. The phrase “essentially all” is defined as “at least 95%”; if essentially all members of a group have a certain property, then at least 95% of members of the group have that property. In some aspects, essentially all means equal to any one of, at least any one of, or between (inclusive or exclusive) any two of 95, 96, 97, 98, 99, or 100% of members of the group have that property. The compositions and methods for their use may “comprise,” “consist essentially of,” or “consist of” any of the ingredients or steps disclosed throughout the specification. Throughout this specification, unless the context requires otherwise, the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open-ended and will be understood to imply the inclusion of a stated step or element or group of steps or elements but not the exclusion of any other step or element or group of steps or elements. As a result, the compositions and methods of the present disclosure that “comprise,” “have,” “include” or “contain” one or more elements possesses those one or more elements, but are not limited to possessing only those one or more elements. Likewise, an element of a composition or method of the present disclosure that “comprises,” “has,” “includes” or “contains” one or more features possesses those one or more features, but is not limited to possessing only those one or more features. It is contemplated that aspects described herein in the context of the term “comprising” may also be implemented in the context of the term “consisting of” or “consisting essentially of.” Compositions and methods “consisting essentially of” any of the ingredients or steps disclosed limits the scope of the claim to the specified materials or steps which do not materially affect the basic and novel characteristic of the claimed disclosure. The words “consisting of” (and any form of consisting of, such as “consist of” and “consists of”) means including, and limited to, whatever follows the phrase “consisting of.” Thus, the phrase “consisting of” indicates that the listed elements are required or mandatory, and that no other elements may be present. Reference throughout this specification to “one aspect,” “an aspect,” “a particular aspect,” “a related aspect,” “a certain aspect,” “an additional aspect,” or “a further aspect” or combinations thereof means that a particular feature, structure or characteristic described in connection with the aspect is included in at least one aspect of the present disclosure. Thus, the appearances of the foregoing phrases in various places throughout this specification are not necessarily all referring to the same aspect. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more aspects. The terms “inhibiting,” “decreasing,” or “reducing” or any variation of these terms, includes any measurable decrease (e.g., at least, at most, exactly, or between (inclusive or exclusive) any two of a 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% decrease) or complete (e.g., 100%) inhibition to achieve a desired result. The terms “improve,” “promote,” or “increase” or any variation of these terms includes any measurable increase (e.g., at least, at most, exactly, or between (inclusive or exclusive) any two of a 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% increase) to achieve a desired result or production of a protein or molecule. As used herein, the terms “reference,” “standard,” or “control” describe a value relative to which a comparison is performed. For example, an agent, subject, population, sample, or value of interest is compared with a reference, standard, or control agent, subject, population, sample, or value of interest. A reference, standard, or control may be tested and / or determined substantially simultaneously and / or with the testing or determination of interest for an agent, subject, population, sample, or value of interest and / or may be determined or characterized under comparable conditions or circumstances to the agent, subject, population, sample, or value of interest under assessment. The term “isolated” may refer to a nucleic acid and / or polypeptide that is substantially free of cellular material, bacterial material, viral material, and / or culture medium (when produced by recombinant DNA techniques) of their source of origin, and / or chemical precursors and / or other chemicals (when chemically synthesized). Moreover, an isolated compound refers to one that may be administered to a subject as an isolated compound; in other words, the compound may not simply be considered “isolated” if it is adhered to a column or embedded in an agarose gel. Moreover, an “isolated nucleic acid fragment” or “isolated peptide” is a nucleic acid or protein fragment that is not naturally occurring as a fragment and / or is not typically in the functional state and / or is altered or removed from the natural state through human intervention. For example, a DNA naturally present in a living animal is not “isolated,” but a synthetic DNA, or a DNA partially or completely separated from the coexisting materials of its natural state, is “isolated.” An isolated nucleic acid may exist in substantially purified form, or may exist in a non-native environment such as, for example, a cell into which the nucleic acid has been delivered. A “nucleic acid,” as used herein, is a molecule comprising nucleic acid components and refers to DNA or RNA molecules. It may be used interchangeably with the term “polynucleotide.” A nucleic acid molecule is a polymer comprising or consisting of nucleotide monomers, which are covalently linked to each other by phosphodiester-bonds of a sugar / phosphate-backbone. Nucleic acids may also encompass modified nucleic acid molecules, such as base-modified, sugar-modified, backbone-modified, etc. DNA or RNA molecules. Nucleic acids may exist in a variety of forms such as: isolated segments and recombinant vectors of incorporated sequences and / or recombinant polynucleotides encoding polypeptides, e.g., antigens or one or both chains of an antibody, or a fragment, derivative, mutein, or variant thereof; polynucleotides sufficient for use as hybridization probes, PCR primers or sequencing primers for identifying, analyzing, mutating or amplifying a polynucleotide encoding a polypeptide; anti-sense nucleic acids for inhibiting expression of a polynucleotide; mRNA; saRNA; and complementary sequences of the foregoing described herein. Nucleic acids may encode an epitope to which antibodies may bind. The term “epitope” refers to a moiety that is specifically recognized by an immunoglobulin (e.g., antibody or receptor) binding component. In some aspects, an epitope is comprised of a plurality of chemical atoms and / or groups on an antigen. In some aspects, such chemical atoms and / or groups are surface-exposed when the antigen adopts a relevant three-dimensional conformation. In some aspects, such chemical atoms and / or groups are physically near to each other in space when the antigen adopts such a conformation. In some aspects, at least some such chemical atoms and / or groups are physically separated from one another when the antigen adopts an alternative conformation (e.g., is linearized). Nucleic acids may be single-stranded or double-stranded and may comprise RNA and / or DNA nucleotides and artificial variants thereof (e.g., peptide nucleic acids). In some cases, a nucleic acid sequence may encode a polypeptide sequence with additional heterologous coding sequences, for example, to allow for purification of the polypeptide, transport, secretion, post-translational modification, and / or for therapeutic benefits such as targeting and / or efficacy. A tag or other heterologous polypeptide may be added to the modified polypeptide-encoding sequence, wherein “heterologous” refers to a polypeptide that is not the same as the modified polypeptide. The term “polynucleotide” refers to a nucleic acid molecule that may be recombinant and / or has been isolated from total genomic nucleic acid. Included within the term “polynucleotide” are oligonucleotides (e.g., nucleic acids 100 residues or less in length) and recombinant vectors, including, for example, plasmids, cosmids, phage, viruses, and the like. Polynucleotides include, in certain aspects, regulatory sequences, isolated substantially away from their naturally occurring genes or protein encoding sequences. Polynucleotides may be single-stranded (coding or antisense) or double-stranded, and may be RNA, DNA (genomic, cDNA, or synthetic), analogs thereof, or a combination thereof. Additional coding or non- coding sequences may, but need not, be present within a polynucleotide. In certain aspects, there are polynucleotide variants having substantial identity to the sequences disclosed herein, such as those comprising at least, at most, exactly, or between (inclusive or exclusive) any two of 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% or higher sequence identity, compared to a polynucleotide sequence provided herein using the methods described herein (e.g., BLAST analysis using standard parameters). In certain aspects, the isolated polynucleotide will comprise a nucleotide sequence encoding a polypeptide that has at least 90% identity to an amino acid sequence described herein, over the entire length of the sequence; or a nucleotide sequence complementary to said isolated polynucleotide. In some aspects, the isolated polynucleotide will comprise a nucleotide sequence encoding a polypeptide that has at least 95% identity to an amino acid sequence described herein, over the entire length of the sequence; or a nucleotide sequence complementary to said isolated polynucleotide. In some aspects, the isolated polynucleotide will comprise a nucleotide sequence encoding a polypeptide that has at least 99% identity to an amino acid sequence described herein, over the entire length of the sequence; or a nucleotide sequence complementary to said isolated polynucleotide. The nucleic acid segments, regardless of the length of the coding sequence itself, may be combined with other nucleic acid sequences, such as promoters, polyadenylation signals, additional restriction enzyme sites, multiple cloning sites, other coding segments, and the like, such that their overall length may vary considerably. The nucleic acids may be any length. They may be, for example, at least, at most, exactly, or between (inclusive or exclusive) any two of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 125, 175, 200, 250, 300, 350, 400, 450, 500, 750, 1000, 1500, 3000, 5000, 6000, 7000, 8000, 9000, 10000, 11000, 12000, 13000, 14000, 15000 or more nucleotides in length, and / or may comprise one or more additional sequences, for example, regulatory sequences, and / or be a part of a larger nucleic acid, for example, a vector. It is therefore contemplated that a nucleic acid fragment of almost any length may be employed, with the total length being limited by the ease of preparation and use in the intended recombinant nucleic acid protocol. In some aspects, 1, 2, 3, or more of the foregoing nucleic acid sequences can be excluded from the nucleic acid segments of the disclosure. As used herein, the term “gene” refers to a nucleic acid that encodes a protein, polypeptide, or peptide (including any sequences required for proper transcription, post- translational modification, and / or localization). As will be understood by those in the art, this term encompasses genomic sequences, expression cassettes, cDNA sequences, and smaller engineered nucleic acid segments that express, or may be adapted to express, proteins, polypeptides, domains, peptides, fusion proteins, and mutants. A nucleic acid encoding all or part of a polypeptide may contain a contiguous nucleic acid sequence encoding all or a portion of such a polypeptide. It also is contemplated that a particular polypeptide may be encoded by nucleic acids containing variations having slightly different nucleic acid sequences but, nonetheless, encode the same or a substantially similar polypeptide. As used herein, the term “expression” of a nucleic acid sequence refers to the generation of any gene product from the nucleic acid sequence. In some aspects, a gene product may be a transcript. In some aspects, a gene product may be a polypeptide. In some aspects, expression of a nucleic acid sequence involves one or more of the following: (1) production of an RNA template from a DNA sequence (e.g., by transcription); (2) processing of an RNA transcript (e.g., by splicing, editing, etc.); (3) translation of an RNA into a polypeptide or protein; and / or (4) post-translational modification of a polypeptide or protein. In some aspects, 1, 2, 3, or more of the foregoing steps can be excluded from expression of nucleic acid sequences of the disclosure. In general, the term “engineered” refers to the aspect of having been manipulated by the hand of man. For example, a polynucleotide is considered to be “engineered” when two or more sequences that are not linked together in that order in nature are manipulated by the hand of man to be directly linked to one another in the engineered polynucleotide and / or when a particular residue in a polynucleotide is non-naturally occurring and / or is caused through action of the hand of man to be linked with an entity or moiety with which it is not linked in nature. The term “DNA,” as used herein, means a nucleic acid molecule comprising nucleotides such as deoxy-adenosine-monophosphate, deoxy-thymidine-monophosphate, deoxy-guanosine-monophosphate and deoxy-cytidine-monophosphate monomers which are composed of a sugar moiety (deoxyribose), a base moiety and a phosphate moiety, and polymerize by a characteristic backbone structure. The backbone structure is, typically, formed by phosphodiester bonds between the sugar moiety of the nucleotide, e.g., deoxyribose, of a first and a phosphate moiety of a second, adjacent monomer. The specific order of the monomers, e.g., the order of the bases linked to the sugar / phosphate-backbone, is called the DNA sequence. DNA may be single stranded or double stranded. In the double stranded form, the nucleotides of the first strand typically hybridize with the nucleotides of the second strand, e.g., by A / T-base-pairing and G / C-base-pairing. DNA may contain all, or a majority of, deoxyribonucleotide residues. As used herein, the term “deoxyribonucleotide” means a nucleotide lacking a hydroxyl group at the 2′ position of a β-D-ribofuranosyl group. Without any limitation, DNA may or may not encompass double stranded DNA, antisense DNA, single stranded DNA, isolated DNA, synthetic DNA, DNA that is recombinantly produced, and modified DNA. The term “RNA,” as used herein, means a nucleic acid molecule comprising nucleotides such as adenosine-monophosphate, uridine-monophosphate, guanosine- monophosphate and cytidine-monophosphate monomers which are connected to each other along a so-called backbone. The backbone is formed by phosphodiester bonds between the sugar, e.g., ribose, of a first and a phosphate moiety of a second, adjacent monomer. RNA may be obtainable by transcription of a DNA-sequence, e.g., inside a cell. In eukaryotic cells, transcription is typically performed inside the nucleus and / or the mitochondria. In vivo, transcription of DNA may result in premature RNA which is processed into messenger-RNA (mRNA). Processing of the premature RNA, e.g., in eukaryotic organisms, comprises various posttranscriptional modifications such as splicing, 5′ capping, polyadenylation, and / or export from the nucleus and / or the mitochondria. Mature messenger RNA is processed and provides the nucleotide sequence that may be translated into an amino acid sequence of a peptide or protein. A mature mRNA may comprise a 5′ cap, a 5′ UTR, an open reading frame, a 3′ UTR and a poly-A tail sequence. In some aspects, 1, 2, 3, or more of the foregoing elements can be excluded from the mature mRNA of the disclosure. RNA may contain all, or a majority of, ribonucleotide residues. As used herein, the term “ribonucleotide” means a nucleotide with a hydroxyl group at the 2′ position of a β-D-ribofuranosyl group. In one aspect, RNA may be messenger RNA (mRNA) that relates to an RNA transcript which encodes a peptide or protein. As known to those of skill in the art, mRNA generally contains a 5′ untranslated region (5′ UTR), a polypeptide coding region, and a 3′ untranslated region (3′ UTR). Without any limitation, RNA may or may not encompass double stranded RNA, antisense RNA, single stranded RNA, isolated RNA, synthetic RNA, RNA that is recombinantly produced, and modified RNA (modRNA). The skilled artisan will appreciate that, except where otherwise noted, nucleic acid sequences set forth in the instant application may recite “T”s in a representative DNA sequence but where the sequence represents RNA (e.g., mRNA), the “T”s would be substituted for “U”s. Thus, any of the DNAs disclosed and identified by a particular sequence identification number herein also disclose the corresponding RNA (e.g., mRNA) sequence complementary to the DNA, where each “T” of the DNA sequence is substituted with “U” (e.g., chemically modified or not chemically modified). An “isolated RNA” is defined as an RNA molecule that may be recombinant and / or has been isolated from total genomic nucleic acid. An isolated RNA molecule and / or protein may exist in substantially purified form, or may exist in a non-native environment such as, for example, a host cell. A “modified RNA” or “modRNA” refers to an RNA molecule having at least one addition, deletion, substitution, and / or alteration of one or more nucleotides as compared to naturally occurring RNA. Such alterations may refer to the addition of non-nucleotide material to internal RNA nucleotides, and / or to the 5′ and / or 3′ end(s) of RNA. In one aspect, such modRNA contains at least one modified nucleotide, such as an alteration to the base of the nucleotide. For example, a modified nucleotide may replace one or more uridine and / or cytidine nucleotides. For example, these replacements may occur for every instance of uridine and / or cytidine in the RNA sequence, or may occur for only select uridine and / or cytidine nucleotides. Such alterations to the standard nucleotides in RNA may include non-standard nucleotides, such as chemically synthesized nucleotides and / or deoxynucleotides. For example, at least one uridine nucleotide may be replaced with N1-methylpseudouridine in an RNA sequence. Other such altered nucleotides are known to those of skill in the art. Such altered RNA molecules are considered analogs of naturally-occurring RNA. In some aspects, the RNA is produced by in vitro transcription using a DNA template, where DNA refers to a nucleic acid that contains deoxyribonucleotides. In some aspects, the RNA may be replicon RNA (replicon), in particular self-replicating RNA, or self-amplifying RNA (saRNA). The terms “protein,” “polypeptide,” or “peptide” are used herein as synonyms and refer to a polymer of amino acid monomers, e.g., a molecule comprising at least two amino acid residues. Polypeptides may include gene products, naturally occurring polypeptides, synthetic polypeptides, homologs, orthologs, paralogs, fragments and other equivalents, variants, and analogs of the foregoing. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing polypeptides can be excluded from the polypeptides of the disclosure. Polypeptides may be a single molecule or may be a multi-molecular complex such as a dimer, trimer or tetramer. A protein comprises one or more peptides or polypeptides, and may be folded into a 3-dimensional form, which may be required for the protein to exert its biological function. As used herein, the terms “wild type” or ”WT” or “native” refer to the endogenous version of a molecule that occurs naturally in an organism. In some aspects, wild type versions of a protein or polypeptide are employed, however, in other aspects of the disclosure, a modified protein or polypeptide is employed to generate an immune response. The terms described above may be used interchangeably. A “modified protein” or “modified polypeptide” or a “variant” refers to a protein or polypeptide whose chemical structure, particularly its amino acid sequence, is altered with respect to the wild type protein or polypeptide. In some aspects, a modified / variant protein or polypeptide has at least one modified activity and / or function (recognizing that proteins or polypeptides may have multiple activities and / or functions). It is specifically contemplated that a modified / variant protein or polypeptide may be altered with respect to one activity and / or function yet retain a wild type activity and / or function in other respects, such as immunogenicity. Where a protein is specifically mentioned herein, it is in general a reference to a native (wild type) or recombinant (modified) protein. The protein may be isolated directly from the organism of which it is native, produced by recombinant DNA / exogenous expression methods, produced by solid-phase peptide synthesis (SPPS) (e.g., an automated method wherein molecules are immobilized on a solid support and synthesized step by step in a reactant solution), liquid phase peptide synthesis (e.g., sequential addition of monomer building blocks in a liquid phase), a combination of solid and liquid phase peptide synthesis, and / or other in vitro methods. Assembling nucleic acids by a ligase may also be used to promote intermolecular ligation of the 5ʹ and 3′ ends of polynucleotide chains through the formation of a phosphodiester bond, and the ligation product produced thereby can, e.g., encode a recombinant protein and / or be used to introduce a protein-encoding nucleic acid into an expression vector. In particular aspects, there are isolated nucleic acid segments and recombinant vectors incorporating nucleic acid sequences that encode a polypeptide (e.g., an antigen or fragment thereof). The term “recombinant” may be used in conjunction with a polypeptide or the name of a specific polypeptide, and this generally refers to a polypeptide produced from a nucleic acid molecule that has been manipulated in vitro and / or that is a replication product of such a molecule. The term “fragment,” with reference to an amino acid sequence (peptide or protein), relates to a part of an amino acid sequence, e.g., a sequence which represents the amino acid sequence shortened at the N-terminus and / or C-terminus. A fragment shortened at the C- terminus (N-terminal fragment) is obtainable, e.g., by translation of a truncated open reading frame that lacks the 3′-end of the open reading frame. A fragment shortened at the N-terminus (C-terminal fragment) is obtainable, e.g., by translation of a truncated open reading frame that lacks the 5′-end of the open reading frame, as long as the truncated open reading frame comprises a start codon that serves to initiate translation. A fragment of an amino acid sequence comprises, e.g., at least 50 %, at least 60 %, at least 70 %, at least 80%, at least 90%, or at least 99% of the amino acid residues from an amino acid sequence. In the present disclosure, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least, at most, exactly, or between (inclusive or exclusive) any two of 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 70% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 80% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 85% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 90% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 95% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 97% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. In one aspect, a fragment of a polypeptide, DNA nucleic acid or RNA nucleic acid sequence refers to a sequence having sequence identity of at least 99% with a polypeptide, DNA nucleic acid or RNA nucleic acid sequence, from which it is derived. As used herein in the context of molecules, e.g., nucleic acids, proteins, or small molecules, the term “variant” refers to a molecule that shows significant structural identity with a reference molecule but differs structurally from the reference molecule, e.g., in the presence or absence or in the level of one or more chemical moieties as compared to the reference entity. In some aspects, a variant also differs functionally from its reference molecule. In general, whether a particular molecule is properly considered to be a “variant” of a reference molecule is based on its degree of structural identity with the reference molecule. As will be appreciated by those skilled in the art, any biological or chemical reference molecule has certain characteristic structural elements. A variant, by definition, is a distinct molecule that shares one or more such characteristic structural elements but differs in at least one aspect from the reference molecule. In some aspects, a variant polypeptide or nucleic acid may differ from a reference polypeptide or nucleic acid as a result of one or more differences in amino acid or nucleotide sequence and / or one or more differences in chemical moieties (e.g., carbohydrates, lipids, phosphate groups) that are covalent components of the polypeptide or nucleic acid (e.g., that are attached to the polypeptide or nucleic acid backbone). Variant antigens / polypeptides encoded by nucleic acids of the disclosure may contain amino acid changes that confer any of a number of desirable properties, e.g., that enhance their immunogenicity, enhance their expression, and / or improve their stability and / or PK / PD properties in a subject. Variant antigens / polypeptides can be made using routine mutagenesis techniques and assayed as appropriate to determine whether they possess the desired property. Assays to determine expression levels and immunogenicity are well known in the art. Similarly, PK / PD properties of a protein variant can be measured using art recognized techniques, e.g., by determining expression of antigens in a vaccinated subject over time and / or by looking at the durability of the induced immune response. The stability of protein(s) encoded by a variant nucleic acid may be measured by assaying thermal stability and / or stability upon urea denaturation and / or may be measured using in silico prediction. Methods for such experiments and in silico determinations are known in the art. In some aspects, a variant polypeptide or nucleic acid shows an overall sequence identity with a reference polypeptide or nucleic acid that is at least, at most, exactly, or between (inclusive or exclusive) any two of 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, or 99%. In some aspects, a variant polypeptide or nucleic acid does not share at least one characteristic sequence element with a reference polypeptide or nucleic acid. In some aspects, a reference polypeptide or nucleic acid has one or more biological activities. In some aspects, a variant polypeptide or nucleic acid shares one or more of the biological activities of the reference polypeptide or nucleic acid. In some aspects, a variant polypeptide or nucleic acid lacks one or more of the biological activities of the reference polypeptide or nucleic acid. In some aspects, a variant polypeptide or nucleic acid shows a reduced level of one or more biological activities as compared to the reference polypeptide or nucleic acid. In some aspects, a polypeptide or nucleic acid of interest is considered to be a “variant” of a reference polypeptide or nucleic acid if it has an amino acid or nucleotide sequence that is identical to that of the reference but for a small number of sequence alterations at particular positions. Preferably, the variant polypeptide or nucleic acid sequence has at least one modification compared to the reference polypeptide or nucleic acid sequence, e.g., from 1 to at least, at most, exactly, or about 20 modifications. In one aspect, the variant polypeptide or nucleic acid sequence has from 1 to at least, at most, exactly, or about 10 modifications compared to the reference polypeptide or nucleic acid sequence. In one aspect, the variant polypeptide or nucleic acid sequence has from 1 to at least, at most, exactly, or about 5 modifications compared to the reference polypeptide or nucleic acid sequence. Typically, fewer than at least, at most, exactly, or about 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, or 2% of the residues in a variant are substituted, inserted, and / or deleted, as compared to the reference. Often, a variant polypeptide or nucleic acid comprises a very small number (e.g., fewer than at least, at most, exactly, or about 5, 4, 3, 2, or 1) of substituted, inserted, and / or deleted, functional residues (e.g., residues that participate in a particular biological activity) relative to the reference. In some aspects, a variant polypeptide or nucleic acid comprises at least, at most, exactly, or about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 substituted residues as compared to a reference. In some aspects, a variant polypeptide or nucleic acid comprises fewer than at least, at most, exactly, or about 25, 20, 19, 18, 17, 16, 15, 14, 13, 10, 9, 8, 7, 6, and commonly fewer than at least, at most, exactly, or about 5, 4, 3, or 2 additions and / or deletions as compared to the reference. In some aspects, a variant polypeptide or nucleic acid comprises not more than at least, at most, exactly, or about 5, 4, 3, 2, or 1 addition and / or deletion, and, in some aspects, comprises no additions and / or deletions, as compared to the reference. In some aspects, a reference polypeptide or nucleic acid is a “wild type” or “WT” or “native” sequence found in nature, including allelic variations. A wild type polypeptide or nucleic acid sequence has a sequence that has not been intentionally modified. For the purposes of the present disclosure, “variants” of an amino acid sequence (peptide, protein, or polypeptide) comprise amino acid insertion variants, amino acid addition variants, amino acid deletion variants and / or amino acid substitution variants. “Variants” of a nucleotide sequence comprise nucleotide insertion variants, nucleotide addition variants, nucleotide deletion variants and / or nucleotide substitution variants. The term “variant” includes all mutants, splice variants, post-translationally modified variants, conformations, isoforms, allelic variants, species variants, and species homologs, in particular, those which are naturally occurring. The term “variant” includes, in particular, fragments of an amino acid or nucleic acid sequence. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing variants can be excluded. A fragment or variant of an amino acid sequence (peptide or protein) may be a “functional fragment” or “functional variant.” The term “functional fragment” or “functional variant” of an amino acid sequence relates to any fragment or variant exhibiting one or more functional properties identical or similar to those of the amino acid sequence from which it is derived, e.g., it is functionally equivalent. With respect to antigens or antigenic sequences, one particular function is one or more immunogenic activities displayed by the amino acid sequence from which the fragment or variant is derived. The term “functional fragment” or “functional variant,” as used herein, in particular refers to a variant molecule or sequence that comprises an amino acid sequence that is altered by one or more amino acids compared to the amino acid sequence of the parent molecule or sequence and that is still capable of fulfilling one or more of the functions of the parent molecule or sequence, e.g., inducing an immune response. In one aspect, the modifications in the amino acid sequence of the parent molecule or sequence do not significantly affect and / or alter the characteristics of the molecule or sequence. An amino acid sequence (peptide, protein, or polypeptide) “derived from” a designated amino acid sequence (peptide, protein, or polypeptide) refers to the origin of the first amino acid sequence. Preferably, the amino acid sequence which is derived from a particular amino acid sequence has an amino acid sequence that is identical, essentially identical, or homologous to that particular sequence or a fragment thereof. Amino acid sequences derived from a particular amino acid sequence may be variants of that particular sequence or a fragment thereof. For example, it will be understood by one of ordinary skill in the art that the antigens suitable for use herein may be altered such that they vary in sequence from the naturally occurring or native sequences from which they were derived, while retaining the desirable activity of the native sequences. Changes may be introduced by mutation into a nucleic acid, thereby leading to changes in the amino acid sequence of a polypeptide (e.g., an antigen or antibody or antibody derivative) that it encodes. Mutations may be introduced using any technique known in the art. In one aspect, one or more particular amino acid residues are changed using, for example, a site-directed mutagenesis protocol. In another aspect, one or more randomly selected residues are changed using, for example, a random mutagenesis protocol. In some aspects, however it is made, a mutant polypeptide may be expressed and screened for a desired property. Mutations may be introduced into a nucleic acid without significantly altering the biological activity of a polypeptide that it encodes. For example, one may make nucleotide substitutions leading to amino acid substitutions at non-essential amino acid residues. Alternatively, one or more mutations may be introduced into a nucleic acid that selectively changes the biological activity of a polypeptide that it encodes. For example, the mutation may quantitatively and / or qualitatively change the biological activity. Examples of quantitative changes include increasing, reducing or eliminating the activity. Examples of qualitative changes include altering the antigen specificity of an antibody. “Sequence similarity” indicates the percentage of amino acids that either are identical or that represent conservative amino acid substitutions. “Sequence identity” between two amino acid sequences indicates the percentage of amino acids that are identical between the sequences. The terms “% identical,” “% identity,” or similar terms are intended to refer, in particular, to the percentage of nucleotides or amino acids which are identical in an optimal alignment between the sequences to be compared. Said percentage is purely statistical, and the differences between the two sequences may be but are not necessarily randomly distributed over the entire length of the sequences to be compared. Comparisons of two sequences are usually carried out by comparing the sequences, after optimal alignment, with respect to a segment or “window of comparison,” in order to identify local regions of corresponding sequences. The optimal alignment for a comparison may be carried out manually and / or with the aid of the local homology algorithm by Smith and Waterman, 1981, Ads. App. Math. 2, 482, with the aid of the local homology algorithm by Neddleman and Wunsch, 1970, J. Mol. Biol.48, 443, with the aid of the similarity search algorithm by Pearson and Lipman, 1988, Proc. Natl Acad. Sci. USA 88, 2444, and / or with the aid of computer programs using said algorithms (FOGSAA, GAP, BESTFIT, FASTA, BLAST P, BLAST N, and TFASTA in Wisconsin Genetics Software Package, Genetics Computer Group). In some aspects, percent identity of two sequences is determined using the BLASTN or BLASTP algorithm, as available on the United States National Center for Biotechnology Information (NCBI) website. Percentage identity is obtained by determining the number of identical positions at which the sequences to be compared correspond, dividing this number by the number of positions compared (e.g., the number of positions in the reference sequence), and multiplying this result by 100. In some aspects, the degree of similarity or identity is given for a region that is at least, at most, exactly, between (inclusive or exclusive) any two of, or about 50%, 60%, 70%, 80%, 90%, or 100% of the entire length of the reference sequence. For example, if the reference nucleic acid sequence consists of 200 nucleotides, the degree of identity is given for at least, at most, exactly, between (inclusive or exclusive) any two of, or about 100, 120, 140, 160, 180, or 200 nucleotides, in some aspects, continuous nucleotides. In some aspects, the degree of similarity or identity is given for the entire length of the reference sequence. Homologous amino acid sequences may exhibit at least, at most, exactly, or between (inclusive or exclusive) any two of 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98%, or 99% identity of the amino acid residues. In one aspect, homologous amino acid sequences exhibit at least 95% identity of the amino acid residues. In one aspect, homologous amino acid sequences exhibit at least 98% identity of the amino acid residues. In one aspect, homologous amino acid sequences exhibit at least 99% identity of the amino acid residues. In the present disclosure, a vector refers to a nucleic acid molecule, such as an artificial nucleic acid molecule. A vector may be used to incorporate a nucleic acid sequence, such as a nucleic acid sequence comprising an open reading frame. Vectors include, but are not limited to, storage vectors, expression vectors, cloning vectors, and transfer vectors. In some aspects, 1, 2, 3, or more of the foregoing vectors can be excluded. A vector may be an RNA vector or a DNA vector. In some aspects the vector is a DNA molecule. In some aspects, the vector is a plasmid vector. In some aspects, the vector is a viral vector. Typically, an expression vector will contain a desired coding sequence and appropriate other sequences necessary for the expression of the operably linked coding sequence in a particular host organism (e.g., bacteria, yeast, plant, insect, or mammal) or in in vitro expression systems. Cloning vectors are generally used to engineer and amplify a certain desired fragment (typically a DNA fragment), and may lack functional sequences needed for expression of the desired fragment(s). As contemplated herein, without any limitations, RNA may be used as a therapeutic modality to treat and / or prevent a number of conditions in mammals, including humans. Methods described herein comprise administration of the RNA described herein to a mammal, such as a human. For example, in one aspect such methods of use for RNA include an antigen-coding RNA vaccine to induce robust neutralizing antibodies and accompanying / concomitant T cell response to achieve protective immunization. In some aspects, minimal vaccine doses are administered to induce robust neutralizing antibodies and accompanying / concomitant T cell response to achieve protective immunization. In one aspect, the RNA administered is in vitro transcribed RNA. For example, such RNA may be used to encode at least one antigen intended to generate an immune response in a mammal. Pathogenic antigens are peptide or protein antigens derived from a pathogen associated with infectious disease. In specific aspects, the pathogenic antigens are peptide or protein antigens derived from EBV. Conditions and / or diseases that may be treated with RNA disclosed herein include, but are not limited to, those caused and / or impacted by EBV infection, such as infectious mononucleosis, autoimmune diseases (e.g. multiple sclerosis), and cancer. “Treating” or “treatment,” as used herein when used in connection with the occurrence of a disease, disorder, and / or condition, refers to the treatment of the disease or condition of interest in a mammal, preferably a human, having the disease or condition of interest, and includes: (i) preventing the disease or condition from occurring in a mammal, in particular, when such mammal is predisposed to the condition but has not yet been diagnosed as having it; (ii) inhibiting the disease or condition, e.g., arresting its development; (iii) relieving the disease or condition, e.g., causing regression of the disease or condition; and / or (iv) relieving the symptoms resulting from the disease or condition, e.g., relieving pain without addressing the underlying disease or condition. In some aspects, 1, 2, 3, or more of the foregoing forms of treatment can be excluded. As used herein, the terms “disease” and “condition” may be used interchangeably or may be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been worked out) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, wherein a more or less specific set of symptoms have been identified by clinicians. “Prevent” or “prevention,” as used herein when used in connection with the occurrence of a disease, disorder, and / or condition, refers to reducing the risk of developing the disease, disorder and / or condition and / or to delaying onset of one or more characteristics or symptoms of the disease, disorder or condition. Prevention may be considered complete when onset of a disease, disorder, or condition has been delayed for a predefined period of time. As will be understood from context, “risk” of a disease, disorder, and / or condition refers to a likelihood that a particular individual will develop the disease, disorder, and / or condition. In some aspects, risk is expressed as a percentage. In some aspects, risk is at least, at most, exactly, or between (inclusive or exclusive) any two of from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90 up to 100%. In some aspects risk is expressed as a risk relative to a risk associated with a reference sample or group of reference samples. In some aspects, a reference sample or group of reference samples have a known risk of a disease, disorder, condition and / or event. In some aspects a reference sample or group of reference samples are from individuals comparable to a particular individual. In some aspects, risk may reflect one or more genetic attributes, e.g., which may predispose an individual toward development (or not) of a particular disease, disorder and / or condition. In some aspects, risk may reflect one or more epigenetic events or attributes and / or one or more lifestyle or environmental events or attributes. An individual who is “susceptible to” a disease, disorder, and / or condition is one who has a higher risk of developing the disease, disorder, and / or condition than does a member of the general public. In some aspects, an individual who is susceptible to a disease, disorder and / or condition may not have been diagnosed with the disease, disorder, and / or condition. In some aspects, an individual who is susceptible to a disease, disorder, and / or condition may exhibit symptoms of the disease, disorder, and / or condition. In some aspects, an individual who is susceptible to a disease, disorder, and / or condition may not exhibit symptoms of the disease, disorder, and / or condition. In some aspects, an individual who is susceptible to a disease, disorder, and / or condition will develop the disease, disorder, and / or condition. In some aspects, an individual who is susceptible to a disease, disorder, and / or condition will not develop the disease, disorder, and / or condition. As used herein, the term “pharmaceutical composition” refers to an active agent, formulated together with one or more pharmaceutically acceptable carriers approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals. Pharmaceutical compositions may be immunogenic compositions. In some aspects, active agent is present in a unit dose amount appropriate for administration in a therapeutic regimen that shows a statistically significant probability of achieving a predetermined therapeutic effect when administered to a relevant population. In some aspects, pharmaceutical compositions may be specially formulated for parenteral administration, for example, by subcutaneous, intramuscular, intravenous and / or epidural injection as, for example, a sterile solution or suspension, or sustained-release formulation. As used herein, the term “vaccination” refers to the administration of an immunogenic composition intended to generate an immune response, for example to a disease-associated (e.g., disease-causing) agent (e.g., a virus, such as EBV). In some aspects, vaccination may be administered before, during, and / or after exposure to a disease-associated agent, and in certain aspects, before, during, and / or shortly after exposure to the agent. In some aspects, vaccination includes multiple administrations, appropriately spaced in time, of a vaccine composition. In some aspects, vaccination generates an immune response to an infectious agent. In some aspects, vaccination generates an immune response to a virus, such as EBV. An immune response refers to a humoral response, a cellular response, or both a humoral and cellular response in an organism. An immune response may be measured by assays that include, but are not limited to, assays measuring the presence and / or amount of antibodies that specifically recognize a protein and / or cell surface protein, assays measuring T cell activation and / or proliferation, and / or assays that measure modulation in terms of activity and / or expression of one or more cytokines. As used herein, the term “combination therapy” refers to those situations in which a subject is simultaneously exposed to two or more therapeutic regimens (e.g., two or more therapeutic agents). In some aspects, the two or more regimens may be administered simultaneously; in some aspects, such regimens may be administered sequentially (e.g., all “doses” of a first regimen are administered prior to administration of any doses of a second regimen); in some aspects, such agents are administered in overlapping dosing regimens. In some aspects, “administration” of combination therapy may involve administration of one or more agent(s) or modality(ies) to a subject receiving the other agent(s) or modality(ies) in the combination. For clarity, combination therapy does not require that individual agents be administered together in a single composition (or even necessarily at the same time), although in some aspects, two or more agents, or active moieties thereof, may be administered together in a combination composition, or even in a combination compound (e.g., as part of a single chemical complex or covalent entity). Those skilled in the art will appreciate that the term “dosing regimen” may be used to refer to a set of unit doses (typically more than one) that are administered individually to a subject, typically separated by periods of time. In some aspects, a given therapeutic agent has a recommended dosing regimen, which may involve one or more doses. In some aspects, a dosing regimen comprises a plurality of doses, each of which is separated in time from other doses. In some aspects, individual doses are separated from one another by a time period of the same length; in some aspects, a dosing regimen comprises a plurality of doses and at least two different time periods separating individual doses. In some aspects, all doses within a dosing regimen are of the same unit dose amount. In some aspects, different doses within a dosing regimen are of different amounts. In some aspects, a dosing regimen comprises a first dose in a first dose amount, followed by one or more additional doses in a second dose amount different from the first dose amount. In some aspects, a dosing regimen comprises a first dose in a first dose amount, followed by one or more additional doses in a second dose amount same as the first dose amount. In some aspects, a dosing regimen is correlated with a desired or beneficial outcome when administered across a relevant population (e.g., is a therapeutic dosing regimen). In some aspects, 1, 2, 3, 4, 5, or more of the foregoing regimens can be excluded. II. EPSTEIN-BARR VIRUS (EBV) EBV is a double-stranded DNA virus that infects B cells and epithelial cells and primarily spreads through body fluids and exchange of saliva in young children and adolescents. Ninety-five percent of the U.S. adult population is EBV-seropositive, with the likelihood of seroprevalence increasing with age. EBV is highly contagious and the cause of infectious mononucleosis (IM), which occurs most frequently in adolescence (17-19 years of age). IM results from a primarily T cell-driven inflammatory response that damages tissues and causes swelling. Although the infection can be resolved in as little as two weeks, IM symptoms can last for 6 months up until one year. Diseases and conditions that are linked to EBV infection include multiple sclerosis, nasopharyngeal carcinoma, Hodgkin’s disease, Burkett’s lymphoma, gastric cancer, and non-Hodgkin lymphoma. The present disclosure provides for RNA molecules (e.g., RNA polynucleotides) comprising at least one open reading frame encoding an EBV polypeptide. The present disclosure further provides for an immunogenic composition comprising at least one RNA molecule encoding an EBV polypeptide complexed with, encapsulated in, and / or formulated with one or more lipids, and forming lipid nanoparticles (LNPs). gp350 / 220 The EBV glycoprotein 350 / 220 (gp350 / 220) is important for efficient EBV infection of human B cells. EBV binds to primary B cells through its interaction with CD21, also known as the complement receptor 2 (CR2), via gp350 / 220. gp350 / 220 is the most abundant viral protein expressed on the surface of the virion envelope and a major target for neutralizing antibodies. Both gp350 and gp220 are encoded by the BLLF1 open reading frame (ORF). Due to alternative splicing, gp220 has a shorter amino acid (aa) length (710 aa) compared to gp350 (907 aa). Both splice forms, gp350 and gp220, can be present on the virus surface and are approximately 350 and 220 kilodaltons in molecular weight, respectively. Both proteins contain a heavily glycosylated, extracellular N-terminal segment (ectodomain), a transmembrane domain, and an intracellular C-terminal tail. Several gp350 / 220 domains are involved in the formation of a stable complex with CD21, one of which has been identified as the CD21 receptor-binding site (aa residues 142 to 161). This glycan-free domain is also recognized by EBV neutralizing monoclonal antibodies (mAbs), such as 72A1. The 72A1 mAb can successfully inhibit EBV binding and invasion of B and T cells, and therefore, underscores the critical role of gp350 / 220 in EBV infection of human lymphocytes. In some aspects of the present disclosure, gp350 or gp220 are encoded by constructs where segments of the gene were removed. In some aspects, gp220 is encoded by constructs generated by splicing of the gp350 RNA sequence. In some aspects, gp350 is encoded by constructs that contain a sequence for a linker (GGGGSx3). Addition of human tissue plasminogen activator (tPA) signal peptide sequence has been shown to enhance both expression and secretion of the encoded protein of interest. In some aspects, gp350 and gp220 are encoded by constructs that contain a sequence for a human tPA signal peptide. One of the major EBV glycoproteins, gp350, is found in monomeric form on the virion surface. Polymerization has been shown to increase immunogenicity of the protein. Fc-based fusion, or fusion of the antigen of interest with the Fc portion of immunoglobulins, can allow for dimerization (polymerization) of the protein. In some aspects of the present disclosure, constructs encode for the complete or partial gp350 ectodomain fused with mouse IgG2a, human IgG1, or human IgG2 Fc domains. These constructs that produce dimeric antigens (e.g., gp350-Fc) may also encode for a linker (GGGGSx3) and an additional signal peptide. Ubiquitin is a protein known to bind to and target other protein substrates for degradation by the 26S proteasome. The proteasome will degrade ubiquitinated proteins and allow various epitopes or peptides to be presented by MHC Class I molecules to CD8+T cells. In some aspects of the present disclosure, gp350 is encoded by ubiquitin-fused constructs with or without mutations in the ubiquitin-encoding and the N-terminal antigen-coding sequences. Examples of such gp350 / 220 sequences are provided in Example 1. gB Engagement of glycoprotein 350 (gp350) with complement receptor type 2 (CR2) is followed by endocytosis of the virus into a low-pH compartment, where fusion with the cell membrane is facilitated by the virus’s core fusion machinery that includes glycoprotein H (gH), glycoprotein L (gL), and glycoprotein B (gB). The EBV gB protein, also referred to as gp110, is a type 1 membrane protein encoded by the BALF4 open reading frame (ORF) and is the most conserved of all the envelope glycoproteins among herpesviruses. Full-length EBV gB is a large protein (857 aa) containing three domains: a glycosylated extracellular N-terminal segment (ectodomain), a transmembrane domain, and an intracellular C-terminal tail. gB is thought to be activated through interaction with gH / gL, although it is not known if this mechanism of activation is the same for epithelial cell entry and B cell endocytosis. EBV gB can mediate fusion with epithelial cells in the absence of the gH / gL complex, however, at a lower level than when all three glycoproteins are present on the virus surface. The C-terminal domain (CTD) of EBV gB is thought to be involved in fusion by regulating the energy threshold for transition between the proposed pre-and post-fusion state of gB. The CTD is also critical for cellular localization in B cells, as it contains endocytosis motifs. In some aspects of the present disclosure, constructs encode for gB with deletions in the CTD and / or transmembrane domain, resulting in a truncated gB protein. Fusion proteins can be rich in hydrophobic and aromatic residues that form bipartite peptides (“loops”) that directly insert into the cell membrane after a conformational change is triggered. Upon activation, gB is thought to insert fusion loops into target cell membranes and is then refolded from a prefusion to a post-fusion form. In EBV gB, the hydrophobic and aromatic residues forming loops are WY112-113and WLIW193-196. In some aspects of the present disclosure, constructs contain mutations in the sequences encoding these residues. Fibritin is a triple-stranded coiled-coil fibrous protein that forms the whiskers of the bacteriophage T4. The T4 fibritin C-terminal domain (27 aa) has the ability to fold and trimerize autonomously (“foldon”). In some aspects, gB constructs encode for a T4 fibritin foldon domain and a linker (GSPGSGSGS) in place of the transmembrane domain and the CTD. Like other gB homologues within the herpesvirus family, EBV gB contains a cleavage Arg–X–Lys / Arg–Arg motif (R-X-K / R-R) that is recognized by the host cellular protease furin. In EBV virions, most gB present is in the cleaved form with only a fraction of total gB in the uncleaved form. Mutations in the gB furin site are known to reduce the level of cell-cell fusion as compared to wild-type EBV. In some aspects, gB constructs contain mutations in the furin site. These same constructs may encode for membrane-anchored (with transmembrane domain or CTD) or soluble (without transmembrane domain or CTD) gB. Examples of such gB sequences are provided in Example 1. gH / gL / gp42 Following initial attachment of EBV gp350 to its B cell ligand, CR2, a complex of three glycoproteins, glycoprotein H (gH), glycoprotein L (gL), and glycoprotein 42 (gp42), is subsequently required for endocytosis. Full-length gH, gL, and gp42 proteins contain a total of 706, 137, and 223 amino acids (aa) residues, respectively. gH, also referred to as gp85, is a type 1 transmembrane protein encoded by the BXLF2 open reading frame (ORF). gL also referred to as gp25, is encoded by the BKRF2 ORF, is a soluble protein required for proper folding and localization of gH. gp42, encoded by the BZLF2 ORF, binds to major histocompatibility complex (MHC) class II molecules (specifically, human leukocyte antigen [HLA] class II in humans) on the B cell surface. The gp42 protein binds to the gH / gL complex with nanomolar affinity through its N-terminal region (approximately 35 amino acid residue interaction). In addition to gH / gL and HLA class II, gp42 is thought to have a third, unidentified potential binding ligand that could be engaged through its large surface-exposed hydrophobic pocket. Entry into B cells, and thus formation of the gH / gL / gp42 trimer, is critical for EBV to establish and maintain latency in the human host. Entry into epithelial cells does not involve interaction between gp42 and HLA class II; instead, the heterodimeric complex of gH / gL, in addition to gB, are sufficient for fusion with the cell membrane of epithelial cells. EBV gH / gL has been shown to engage integrins avβ6 and / or avβ8 on epithelial cells to trigger membrane fusion and entry. gp42 is a type II transmembrane protein with a putative transmembrane domain from amino acid residues 9 to 22 and a cleavage site following the potential signal peptide between amino acid residues 40 and 42. Secreted (soluble) gp42 has been shown to promote membrane fusion with B cells. In some aspects of the present disclosure, a construct encodes for gp42 that lack the potential transmembrane domain and signal peptide but contain the sequence for the gB signal peptide. As gH and gL form a natural heterodimer for fusion with epithelial cells, the resulting protein complex has potential to be encoded by the same messenger RNA (mRNA). In some aspects, constructs encode for gH and gL separately or jointly. In some aspects, constructs contain sequences for gH and gL joined by a linker (GGGGS x3 or x4). In these linked constructs, the gH signal peptide and / or gH transmembrane and cytoplasmic domains may be removed. As gH, gL, and gp42 form a natural heterotrimer for entry into B cells, the resulting protein complex has potential to be encoded by the same mRNA. In some aspects of the present disclosure, constructs encode for gH, gL, and gp42 individually, together, or in different combinations. In some aspects, constructs contain sequences for gH, gL, and gp42 joined by a linker (GGGGS x3 or x4 or x5). The same constructs may contain sequences for gH with or without the transmembrane domain and CTD. The same constructs may contain sequences for the gp42 potential transmembrane domain and signal peptide. Ubiquitin is a protein known to bind to and target other protein substrates for degradation by the 26S proteasome. The proteasome will degrade ubiquitinated proteins and allow various epitopes or peptides to be presented by MHC Class I molecules to CD8+T cells. In some aspects of the present disclosure, gp42 is encoded by ubiquitin-fused constructs with or without mutations in the ubiquitin-encoding region. Examples of such gH / gL / gp42 sequences are provided in Example 1. BMRF-2 and BDLF-2 BMRF-2 is a glycoprotein encoded by the rightward frame 2 (BMRF2) open-reading frame (ORF), which is highly conserved in γ-herpesviruses. BMRF-2 is expressed during EBV lytic infection in B cells and oral epithelial cells. Domains for BMRF- 2 are less clear than for other EBV glycoproteins. BMRF-2 is glycosylated through O-linked oligosaccharides and is associated with the virion envelope. Full-length BMRF-2 (357 amino acids) is predicted to have multiple (potentially 11) transmembrane domains with evidence to support the C-terminal tail being located in the cytoplasm, suggesting that the N-terminus is located external to the virion. The BMRF-2 protein contains a critical Arg–Gly–Asp (RGD) motif that binds to β1, α5, α3, and αv integrins. Interaction of BMRF-2 with cellular integrins mediates the tethering and subsequent entry of EBV through the basolateral membrane of polarized oral epithelial cells. BDLF-2, encoded by the leftward frame 2 (BDLF2) ORF, is type II membrane protein (420 amino acids) containing three domains: an intravirion region, a transmembrane domain, and a virion surface exposed region. It has been proposed that BMRF-2 and BDLF-2, when co-expressed, form heteromeric complexes that travel through the secretory pathway and reorganize the actin cytoskeleton. Once localized at the plasma membrane, BMRF-2-BDLF-2 interactions may facilitate virion spread between cells. Thus, BMRF-2 and BDLF-2, involved in the attachment of EBV to the oral epithelium and subsequent cell-to-cell spread, play an important role in primary EBV infections. In some aspects of the present disclosure, constructs encode for one or more BMRF- 2 RGD domains joined by a linker (GGGGSx3 or x4) and may include sequences for the gH transmembrane domain and cytoplasmic tail. Addition of human tissue plasminogen activator (tPA) signal peptide sequence has been shown to enhance both expression and secretion of the encoded protein of interest. The same constructs may also include a sequence for the human tPA signal peptide. In some aspects of the present disclosure, constructs encoding one or more BMRF-2 RDG domains joined by linkers (GGGGSx3 or x4) also encode for gH, gL, and / or gp42 that lacks the transmembrane domain. These same constructs may encode for the gB or gL signal peptide. In some aspects, constructs encode for a BDLF-2 truncated mutant in which specific domains (e.g., intravirion, transmembrane) are deleted. The same constructs may also include a sequence for the human tPA signal peptide. Examples of such BMRF-2 and BDLF-2 sequences are provided in Example 1. EBNA1 Epstein Barr nuclear antigen 1 (EBNA1) is one of several nuclear antigens encoded by the BKRF1 open reading frame and the most widely studieds of all EBV proteins. Expression of EBNA1 occurs in all latency stages (except latency 0) in proliferating cells and is also found in all EBV-linked diseases and malignancies. EBNA1 is essential for latent-phase DNA replication, thereby maintaining the EBV genome and persistent infection; however, it must depend on host cellular proteins to replicate viral episomes (circular viral genomic dsDNA, akin to a plasmid) due to its inherent lack of enzymatic activity. EBNA1 (641 aa) plays important roles in viral DNA replication, mitotic segregation and episomal partitioning, transcriptional activation, and autoregulation. All of these functions involve EBNA1 binding to specific DNA recognition sites in the EBV latent origin of DNA replication (oriP), comprised of the dyad symmetry (DS) element and the family of repeats (FR) element. The DNA binding and dimerization domain of EBNA1 spans 148 residues at the C-terminal end of the antigen; this region interacts with four critical binding sites in the oriP DS element, which is essential for DNA replication. In addition, EBNA1 binds to ubiquitin-specific protease 7 (USP7) through residues 442-448, thereby recruiting USP7 to the oriP. This interaction has effects related to negative regulation of replication, transcriptional activation, promyelocytic leukemia protein (PML) nuclear body degradation, and possibly cell survival. EBNA1 functions in mitotic segregation by tethering the EBV episomes to the cellular chromosomes. For segregation (partitioning of the EBV episomes) to occur, EBNA1 must bind to multiple recognition sites (~20 tandem copies of a 30-bp sequence) in the oriP FR. Studies experimenting with deletions in the central Gly–Arg-rich region (residues 325-376) have shown this EBNA1 region is critical for chromosome attachment, and that N-terminal sequences (residues 8-67) can contribute to this interaction. EBNA1 can also act as a transcriptional activator when bound to the oriP FR element. Two EBNA1 sequences are required for efficient transcriptional activation: the central Gly-Arg-rich region and an N- terminal sequence (residues 61-89). The bromodomain protein, Brd4, and nucleosome assembly protein, NAP1, are two examples of cellular proteins recruited to the oriP FR by EBNA1, and depletion of either protein decreases EBNA1 transcriptional activation activity. When cellular levels of EBNA1 are enough to saturate DS and FR elements in the oriP, EBNA1 will bind sites downstream of the Qp promoter, thus providing an auto-regulatory, feedback mechanism to limit its own expression when levels are high. EBNA1 has also been implicated in EBV-mediated immune evasion and molecular mimicry. As EBNA1 is critically expressed in all proliferating, latently-infected B cell stages, a robust EBNA1-specific cytotoxic T lymphocyte (CTL, CD8+T cell) response is desirable to target and eradicate EBV-infected B cells before disease symptoms progress. The Gly–Ala repeat region (GAr, residues 90-324) has been shown to inhibit antigen processing via the ubiquitin / proteasome pathway (Levitskaya et al. Proc Natl Acad Sci U S A. 1997;94(23):12616-12621) and suppression of autophagy (Tovar Fernandez et al. Cell Immunol.2022;374:104484), resulting in poor human leukocyte antigen (HLA) presentation of EBNA1 to CD8+T cells. In addition, EBNA1 translation and levels of defective ribosomal products (DRiPs) in the cytoplasm, both of which are inhibited by the GAr, affect rates of the protein’s HLA presentation and CTL recognition (Frappier Curr Top Microbiol Immunol. 2015;391:3-34; Tellam et al. PLoS Pathog. 2014;10(10):e1004423. Published 2014 Oct 9; Apcher et al. PLoS Pathog. 2010;6(10):e1001151. Published 2010 Oct 14; Apcher et al. J Virol.2009;83(3):1289-1298). Several EBNA1 peptides have also been identified as having cellular protein mimics (Solan and Lieberman 2023) and elevated antibodies targeting EBNA1 have been associated with the autoimmune disease multiple sclerosis (MS) (Wang et al. J Neuroimmune Pharmacol. 2021;16(3):567-580; Ruprecht Expert Rev Clin Immunol. 2020;16(12):1143-1157; Jafari et al. J Clin Virol.2010;49(1):26-31; Salzer et al. Mult Scler. 2013;19(12):1587-1591; Sundqvist et al.2012 Genes Immun.2012;13(1):14-20). Antibodies directed against the EBNA1380-450 region have been described in MS and can bind to central nervous system (CNS) proteins, such as glial cellular adhesion molecule (GlialCAM) (Lanz et al. Nature 2022 Mar;603(7900):321-327), providing evidence of molecular mimicry between EBNA1 and self-antigens (Tengvall et al. Proc Natl Acad Sci U S A. 2019;116(34):16955-16960; Thomas et al. Sci Adv.2023;9(20):eadg3032). How EBNA1 can be both a poorly-presented, immune evader and auto-antibody inducer in the setting of MS remains unclear. In some instances, constructs encode for a mosaic EBNA1 mutants which retain one or more of the Gly–Arg-rich domains but not all Gly-rich domains. In some instances, constructs encode for a truncated EBNA1 mutant in which Gly-rich segments are deleted, inclusive of Gly–Arg-rich, GAr, and molecular mimicry regions. In some instances, constructs encode for a mutation in the NLS or its deletion to prevent or lessen EBNA1 function in the nucleus. Some constructs encode for C-terminal regions of EBNA1, inclusive of the core binding and dimerization with or without the associated flanking domain component, or the casein kinase 2 (CK2) and USP7 binding sites and NLS that may be joined by linkers. These constructs produce truncated EBNA1 proteins. Ubiquitin is a protein known to bind to and target other protein substrates for degradation by the 26S proteasome. The proteasome will degrade ubiquitinated proteins and allow various epitopes or peptides to be presented by MHC Class I molecules to CD8+T cells. In some instances, a truncated EBNA1 is encoded by ubiquitin-fused constructs with mutations in the ubiquitin-encoding region. These same constructs may also contain a destabilizing mutation in EBNA1-encoding region. As previously mentioned, proteins can be targeted for degradation by the proteasome by fusing the protein of interest to a ubiquitin molecule. Another way to target a protein for degradation is through the addition of degrons to the protein of interest; degrons are short amino acid sequences, ligands, or motifs. The efficiency of the degradation depends on several factors including the design of the protein of interest as well as the design and location of the ubiquitin / degron. For the protein of interest, the amino acid content can influence the ability of the proteasome to recognize the protein of interest. For example, proteins with hydrophobic and nonpolar amino acid residues as well as stiffer polypeptide chains in the initiation region are more likely to be degraded (Tomita T, & Matouschek A., Protein Sci.2019;28(7):1222-32, Yu H, et al., J Biol Chem.2016;291(28):14526-39). In some instances, constructs encode for a truncated EBNA1 protein with the C-terminal acidic tail removed as these residues could inhibit recognition of the protein for degradation by the proteasome. Furthermore, as previously mentioned, EBNA1 contains a USP7 binding site at residues 442-448. USP7 (also known as HAUSP) is a ubiquitin-specific protease that has been shown to cleave ubiquitin from EBNA1- ubiquitin conjugates in vitro (Holowaty MN, et al., J Biol Chem. 2003;278(48):47753-61, Holowaty MN, et al. J Biol Chem. 2003;278(32):29987-94). In some instances, constructs encode for a truncated EBNA1 protein with the USP7 binding site removed. Degrons can be attached at either the N-terminal (N-degrons) or C-terminal (C- degrons) end of a protein of interest and can lead to degradation via a ubiquitin-dependent or ubiquitin-independent degradation pathway. When ubiquitin is covalently attached to a protein of interest without any mutations in the ubiquitin molecule, degradation proceeds according to the N-end rule pathway (Bachmair A, et al., Science 1986;234(4773):179-86; Varshavsky A. Proc Natl Acad Sci U S A. 2019;116(2):358-66; Andersson HA, & Barry MA. Mol Ther. 2004;10(3):432-46). In this pathway, the N-terminal residue following ubiquitin cleavage determines the half-life of the protein, with some residues being more destabilizing than others (Bachmair A, et al., Science. 1986;234(4773):179-86; Chassin H, et al., Nat Commun. 2019;10(1):2013.). When the last residue of ubiquitin is mutated from glycine to valine (G76V), the ubiquitin is unable to be cleaved from the protein of interest and proceeds to polyubiquitination as part of the ubiquitin fusion degradation (UFD) pathway (Johnson ES, et al., EMBO J.1992;11(2):497-505; Johnson ES, et al., J Biol Chem.1995;270(29):17442-56). Furthermore, ubiquitin can be fused to a protein of interest as a single copy or as multiple copies (Chassin H, et al., Nat Commun. 2019;10(1):2013). In some instances, constructs encode for a truncated EBNA1 protein preceded by a single copy of ubiquitin followed by a R, K, P, or M residue. In other instances, constructs encode for a truncated EBNA1 protein preceded by a single or multiple copies of ubiquitin with the G76V mutation in combination with an additional V or R residue. Several C-degrons have been described in the literature (Varshavsky A., Proc Natl Acad Sci U S A.2019;116(2):358-66; Koren I, et al., Cell 2018;173(7):1622-35 e14; Lin HC, et al., Mol. Cell.2018;70(4):602-13 e3). Both N- and C-degrons can depend on specific E3 ligases as part of the ubiquitin proteasome pathway. In this pathway, E3 ubiquitin ligases are responsible for mediating transfer of activated ubiquitin from enzyme E2 to the substrate protein (Varshavsky A. Trends Biochem Sci.1997;22(10):383-7). In mammals, there are over 600 E3 ligases that are split into three families; this variation leads to the specificity of ubiquitination for substrate proteins (Ji L, et al., Int J Mol Sci.2022;23(23)). In some instances, constructs encode for a truncated EBNA1 protein preceded by a ubiquitin-dependent N- degron. In other instances, constructs encode for a truncated EBNA1 protein followed by ubiquitin-dependent C-degron. Alternatively, there are N- and C-degrons that result in degradation of proteins independent of the ubiquitin pathway. In some instances, constructs encode for a truncated EBNA1 protein followed by a ubiquitin-independent C-degron. In other instances, constructs encode for a truncated EBNA1 protein in combination with both a ubiquitin-independent N-terminal proteasome recruitment tag (Yu H, et al., EMBO J. 2016;35(14):1522-36) and a C-terminal proteasome initiation region.In some instances, constructs encode for a truncated EBNA1 mutant with a unique peptide sequence inserted at the 5’ end of the USP7 binding site. These same constructs may contain mutations in the peptide-encoding sequence or are ubiquitin-fused with mutations in the ubiquitin-encoding region. In some instances, constructs encode for a truncated EBNA1 mutant that contains mutations in the sequence encoding the core and flanking components of the DNA binding and dimerization domain. EBNA1 is considered a robust immunogen and EBNA1-specific CD4+and CD8+T cells have been shown to react with EBV-transformed B cells (Blake et al. Immunity 1997;7(6):791- 802; Long et al. J Virol.2005;79(8):4896-4907; Münz et al. J Exp Med.2000;191(10):1649- 1660; Nikiforow et al. J Virol. 2003;77(22):12088-12104; Paludan and Münz Curr Mol Med. 2003;3(4):341-347). However, molecular mimicry between host proteins and EBNA1 means that design of EBNA1-based vaccines should be approached with caution. Removal of molecular mimicry sites from EBNA1 can help elicit antiviral immune responses that minimize risk of auto-reactivity. In some instances, constructs encode for a protein containing CD8+T cell epitopes in tandem repeats (x5 or x10). These constructs may also be ubiquitin-fused and contain mutations in the ubiquitin-encoding region.Examples of such EBNA1 sequences are provided in Example 1. EBNA2 Epstein-Barr virus nuclear antigen 2 (EBNA-2) plays a crucial role in B cell immortalization by transactivating several cellular (MYC, FCER2, CR2) and viral genes, and preventing apoptosis of the transformed B cell. During latency III, a EBV transcriptional program phase in which infected B cells undergo EBV-growth associated transformation, the transcription factor EBNA2 (487 aa) is co-expressed with the EBNA-leader protein (EBNA- LP), in which the latter coactivates EBNA2 on a subset of EBNA2-responsive genes. The structure of EBNA2 is characterized by a poly-proline (polyP) and poly-arginine-glycine (RG) stretch and 9 conserved regions (CRs). EBV-infected B cells can be recognized by EBNA2- specific CD8+T cells and their proliferation prevented, suggesting EBNA2 could be targeted by a vaccine to halt or slow initial stages of EBV-linked B cell immortalization. Examples of such EBNA2 sequences are provided in Example 1. EBNA-LP EBNA-leader protein (EBNA-LP; also known as EBNA5) helps regulate B cell immortalization as a coactivator of several, but not all, EBNA2- responsive genes, and is essential for the survival of EBV-infected naive B cells (Szymula A, et al., PLoS Pathog. 2018;14(2):e1006890). EBNA2 / EBNA-LP co- transcriptional activation preferentially enhances the expression of LMP1 and LMP2B RNAs (Peng R, et al., J Virol.2005;79(7):4492-505). EBNA-LP (506 aa) specifically displaces promyelocytic leukemia nuclear body (PML NB)-associated protein Sp100A and heterochromatin protein 1α (HP1α) from PML NBs (Ling PD, et al., EMBO J. 2005;24(20):3565-75), and this activity correlates positively with EBNA2 coactivation (Echendu CW & Ling PD, J Interferon Cytokine Res.2008;28(11):667-78). EBNA-LP consists of the multiple-repeat domain encoded by the repeating W1 and W2 exons in the major internal repeat (IR1) followed by the C-terminal domain encoded by the unique Y1 and Y2 exons, which are located downstream of the 3′ end of IR1 (Sample J, et al., J Virol.1986;57(1):145-54). In newly EBV-infected B cells, several isoforms of EBNA-LP can be detected, possibly as a result of heterogeneous polypeptides with different numbers of W1W2 repeats or due to alternative splicing (Peng R, et al., J Virol.2005;79(7):4492-505), Finke J, et al., J Virol.1987;61(12):3870-8). Examples of such EBNA-LP sequences are provided in Example 1. EBNA3 Epstein-Barr virus nuclear antigen 3 (EBNA3) proteins are a family of nuclear EBV antigens. The EBNA3 proteins serve as primary targets of cytotoxic T lymphocytes (CTL) in the peripheral circulation of healthy EBV carriers and have been shown to be, among all the latency-associated viral proteins, the most immunogenic (Hislop AD, et al., Annu Rev Immunol. 2007;25:587-617). EBNA3 transcripts are alternatively spliced from long primary transcripts generally initiated at a single latency promoter, resulting in three distinct proteins: EBNA3A (944 aa; also known as EBNA3), EBNA3B (938 aa; also known as EBNA4), and EBNA3C (992 aa; also known as EBNA6). While there is overall low sequence homology among the EBNA3 proteins, they share several features including an N-terminal homology region (~225 aa), multiple nuclear localization signals (NLS), a proline-rich region and repeat sequences. EBNA3A and EBNA3C target tumor suppressor pathways so they are operationally considered oncoproteins while EBNA3B limits EBV oncogenic capacity, so it is considered a tumor suppressor (Allday MJ, et al., Curr Top Microbiol Immunol.2015;391:61- 117).). The key role of the EBNA3 proteins in establishing latency in infected B cells as well as being dominant targets of CD8+T cell responses during natural infection make the EBNA3 proteins promising vaccine antigens. Examples of such EBNA3 sequences are provided in Example 1. LMP1 Latent membrane protein-1 (LMP1) is considered the principal viral oncoprotein of EBV and is expressed during type II and III latency. LMP1(386 aa), an integral membrane protein, initiates the activation of several signaling pathways, such as NF- kappa B (NF-κB), the mitogen-activated protein kinases (MAPK) JNK, ERK, and p38, the small GTPase Cdc42, PI3-K / AKT, IRF7, and the JAK / STAT cascade. LMP1 comprises a short N-terminal cytoplasmic domain, six transmembrane domains, and a long (200aa) C-terminal cytoplasmic tail which contains two signaling domains designated C-terminal activating regions, CTAR1 and CTAR2 (Kieser A, & Sterz KR, Curr Top Microbiol Immunol.2015;391:119-49). The LMP1 cytoplasmic domain acts as a CD40 (a TNF receptor) functional homolog, mimicking the binding of CD40 to TRAF3 to activate similar signaling pathways and prevent apoptosis of the B cell (Wu S, et al., J Biol Chem. 2005;280(39):33620-6). The constitutive engagement of these activating signals due to molecular mimicry contributes to B cell immortalization and proliferation, making it an important therapeutic target for EBV. Examples of such LMP1 sequences are provided in Example 1. LMP2 There are two prominent isoforms of LMP2, LMP2A (497aa) and LMP2B (378aa), that are expressed in type II and type III latency, and are crucial in the establishment and maintenance of latently EBV-infected B cells. LMP2A consists of a 119aa N-terminal domain followed by a transmembrane domain with 12 segments, and then a 27aa C-terminal tail responsible for dimerization; LMP2B lacks the 119aa N-terminal tail present in LMP2A. LMP2A alters signal transduction pathways and can mimic B cell receptor (BCR) signaling through its N-terminal signaling domain, while LMP2B modulates LMP2A distribution and function (Cen O & Longnecker R., Curr Top Microbiol Immunol. 2015;391:151-80). Due to moderate CD8+ T cell responses to LMP2 during infection, this antigen is a potential vaccine candidate and has previously been used in EBV vaccination strategies (Zhao GX, et al., Adv Sci (Weinh). 2023;10(35):e2302116; Guo M, et al., Nano Res. 2023;16(4):5357-67). Examples of such LMP2 sequences are provided in Example 1. BZLF1 The EBV lytic switch protein BZLF1 (also known as ZEBRA, Zta, and EB1) is a bZIP transcriptional activator. BZLF1 binds to heptamer DNA motifs termed ZEBRA response elements (ZREs) found in the promoters of many early lytic EBV genes resulting in induction of lytic infection in latently EBV-infected cells (Adamson AL & Kenney S., J Virol. 1999;73(8):6551-8; Germini D, et al. Cancers (Basel). 2020;12(6)). As the lytic cycle progresses, BZLF1 also acts as a DNA replication factor and provides a lytic origin binding protein function for EBV replication (Kieff E, & Rickinson, A B, Epstein-Barr Virus and Its Replication. In: D. M. Knipe PMH, D. E. Griffin, R. A. Lamb, M. M. Martin, B. Roizman, & S. E. Straus, editor. Fields Virology. Vol. II. Fifth edition ed: Lippincott Williams & Wilkins; 2007. p. pp. 2603-54). BZLF1 (245 aa) is characterized by an N-terminal transactivation domain, followed by a shorter regulatory domain, DNA / bZIP binding domain, and dimerization domain near the C-terminus (Germini D, et al. Cancers (Basel). 2020;12(6)). BZLF1 is highly immunogenic and elicits robust CD8+ T cell responses that dominate the early immune responses in patients with infectious mononucleosis (IM) (Hislop, supra; Tan LC, et al., J Immunol. 1999;162(3):1827-3517; Bogedain C, et al., J Virol. 1995;69(8):4872-9; Precopio ML, et al., J Immunol.2003;170(5):2590-8). As a dominant target of CD8+T cell responses during natural infection, BZLF1 is a promising vaccine antigen target. Vaccination strategies using BZLF1-expressing dendritic cells have been shown to induce specific cellular immunity and prolong survival in animal models of EBV-LPD (Hartlage AS, et al., Cancer Immunol Res. 2015;3(7):787-94). Examples of such BZLF1 sequences are provided in Example 1. BRLF1 (also known as Rta) is a transcriptional activator that binds to promoters of early lytic EBV genes and induces lytic infection in latently EBV-infected cells. The N-terminus of BRFL1 (605 aa) contains the DNA binding and dimerization domains, while the C-terminus contains the transcriptional activation domain (Robinson AR, et al., J Virol.2011;85(17):8940- 53). The cooperative function of BZLF1 and BRLF1 results in the switch from latency to lytic infection (Feederle R, et al., EMBO J.2000;19(12):3080-9). Similar to BZLF1, BRLF1 elicits strong CD8+T cell responses in patients with IM (Hislop, supra, Hislop AD & Taylor GS, Curr Top Microbiol Immunol. 2015;391:325-53). As a key activator of the lytic cycle as well as being a dominant target of CD8+T cell responses during natural infection, BRLF1 is a promising vaccine antigen target. Examples of such BRLF1 sequences are provided in Example 1. BMLF1 The early lytic protein BMLF1 (also known as EB2, SM, or Mta) is a multifunctional RNA-binding protein that affects viral and cellular gene expression through various mechanisms including enhancing mRNA transport, splicing, stability, and translation. BMLF1 (479 aa) is a downstream target of Rta and is the key regulator critically contributing to the activation of the grp78 gene promoter via ATF6 cleavage and activation. Increased expression of GRP78 is associated with assembly and release of EBV virus particles through its function as a regulator of the unfolded response (UPR) signaling pathway (Chen LW, et al., Int J Mol Sci.2021;22(8)). Furthermore, there are substantial CD8+T cell responses to some of the early genes including BMLF1 in people with IM (Hislop supra). The critical role of BMLF1 in lytic cycle progression as well as being a natural target of CD8+T cells makes this antigen a promising vaccine target. Examples of such BMLF1 sequences are provided in Example 1. In some aspects, the RNA molecules disclosed herein comprise an open reading frame encoding at least one EBV polypeptide.

III. RNA MOLECULE In some aspects, the RNA molecule described herein is a coding RNA molecule. Coding RNA includes a functional RNA molecule that may be translated into a peptide or polypeptide. In some aspects, the coding RNA molecule includes at least one open reading frame (ORF) coding for at least one peptide or polypeptide. An open reading frame comprises a sequence of codons that is translatable into a peptide or protein. The coding RNA molecule may include one (monocistronic), two (bicistronic) or more (multicistronic) ORFs, which may be a sequence of codons that is translatable into a polypeptide or protein of interest. The coding RNA molecule may be a messenger RNA (mRNA) molecule, viral RNA molecule, and / or self-amplifying RNA molecule (saRNA, also referred to as a replicon). In some aspects, the RNA molecule is an mRNA. Preferably, the RNA molecule of the present disclosure is an mRNA. In some aspects, the RNA molecule is a saRNA. In some aspects, the saRNA molecule may be a coding RNA molecule. In some aspects, the RNA molecule described herein is a non-coding RNA molecule. A non-coding RNA (ncRNA) molecule includes a functional RNA molecule that is not translated into a peptide or polypeptide. Non-coding RNA molecules may include highly abundant and functionally important RNA molecules. In some aspects, the non-coding RNA is a functional mRNA molecule that is not translated into a peptide or polypeptide. The non- coding RNA may include modified nucleotides as described herein. Preferably, the RNA molecule is an mRNA. The RNA molecule may encode one polypeptide of interest or more, such as an antigen or more than one antigen, e.g., two, three, four, five, six, seven, eight, nine, ten or more polypeptides. Alternatively, or in addition, one RNA molecule may also encode more than one polypeptide of interest, such as an antigen, e.g., a bicistronic, or tricistronic RNA molecule that encodes different or identical antigens. Bicistronic or multicistronic RNAs may include more than one polypeptide of interest with intervening sequences between the polypeptides of interest comprising an internal ribosome entry site (IRES) sequence(s) that allow for internal translation initiation between the polypeptides of interest, and / or with an intervening sequence encoding a self-cleaving peptide, such as a 2A peptide. IRES sequences and 2A peptides may be used, in some aspects, to enhance expression of multiple proteins from the same vector. A variety of IRES sequences are known and available in the art and may be used, including, e.g., the encephalomyocarditis virus IRES. The sequence of the RNA molecule may be codon optimized or deoptimized for expression in a desired host, such as a human cell. In some aspects, a gene of interest (e.g., an antigen) described herein is encoded by a coding sequence which is codon-optimized and / or the guanosine / cytidine (G / C) content of which is increased compared to wild type coding sequence. In some aspects, one or more sequence regions of the coding sequence are codon-optimized and / or increased in the G / C content compared to the corresponding sequence regions of the wild type coding sequence. In some aspects, codon-optimization and / or increasing the G / C content does not change the sequence of the encoded amino acid sequence. As used herein, the term “codon-optimized” refers to modification of codons in the coding region of a nucleic acid molecule to accommodate the codon bias a host organism without a corresponding modification to the amino acid sequence encoded by the nucleic acid molecule. Codon optimization, in some aspects, may be used to match codon frequencies in target and host organisms to ensure proper folding; bias GC content to increase mRNA stability and / or reduce secondary structures; minimize tandem repeat codons and / or base runs that may impair gene construction or expression; customize transcriptional and translational control regions; insert and / or remove protein trafficking sequences; remove / add post translation modification sites in encoded protein (e.g., glycosylation sites); add, remove and / or shuffle protein domains; insert and / or delete restriction sites; modify ribosome binding sites and mRNA degradation sites; adjust translational rates to allow the various domains of the protein to fold properly; and / or reduce or eliminate problem secondary structures within the polynucleotide. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing uses of codon optimization can be excluded. Within the context of the present disclosure, in some aspects, coding regions are codon-optimized for optimal expression in a subject to be treated using an RNA polynucleotide described herein. Codon-optimization is based on the finding that the translation efficiency may be determined by a different frequency in the occurrence of transfer RNAs (tRNAs) in cells. Thus, if so-called “rare codons” are present in the coding region of the inventive artificial nucleic acid molecule as defined herein, to an increased extent, the translation of the corresponding modified nucleic acid sequence is less efficient than in the case, where codons coding for relatively “frequent” tRNAs are present. Thus, the open reading frame of the RNA molecule is modified compared to the corresponding wild type coding region such that at least one codon of the wild type sequence, which is recognized by a tRNA, and which is relatively rare in the cell, is exchanged for a codon, which is recognized by a tRNA, and which is comparably frequent in the cell and carries the same amino acid as the relatively rare tRNA. By this modification, the open reading frame of the RNA molecule is modified such that codons for which frequently occurring tRNAs are available may replace codons that correspond to rare tRNAs. Which tRNAs occur relatively frequently in the cell and which, in contrast, occur relatively rarely, is known to a person skilled in the art (see, e.g., Akashi, Curr. Opin. Genet. Dev.2001 , 11 (6): 660-666), and codon optimization tools, algorithms and services are known in the art, and non-limiting examples include services from GeneArt (Life Technologies), DNA2.0 (Menlo Park CA) and / or proprietary methods. In some embodiments, the open reading frame (ORF) sequence is optimized using optimization algorithms. The sequence of the RNA molecule may be modified if desired, for example to increase the efficacy of expression and / or replication of the RNA, to provide additional stability and / or resistance to degradation, and / or to reduce immunogenicity, relative to an unmodified RNA molecule. For example, the RNA sequence may be modified with respect to its codon usage, for example, to increase translation efficacy and half-life of the RNA. In some aspects, one or more of the foregoing reasons for modification of the RNA molecule can be excluded. In some aspects, the RNA molecule of the present disclosure comprises an open reading frame having at least one codon modified sequence. A codon modified sequence relates to coding sequences that differ in at least one codon (triplets of nucleotides coding for one amino acid) compared to the corresponding wild type coding sequence. A codon modified sequence may show improved resistance to degradation, improved stability, and / or improved translatability. In some aspects, G / C content of a coding region (e.g., of a gene of interest sequence; open reading frame (ORF)) of an RNA is increased compared to the G / C content of the corresponding coding sequence of a wild type RNA encoding the gene of interest, wherein in some aspects, the amino acid sequence encoded by the RNA is not modified compared to the amino acid sequence encoded by the wild type RNA. This modification of the RNA sequence is based on the fact that the sequence of any RNA region to be translated is important for efficient translation of that mRNA. Sequences having an increased G (guanosine) / C (cytidine) content are more stable than sequences having an increased A (adenosine) / U (uridine) content. In respect to the fact that several codons code for one and the same amino acid (so- called degeneration of the genetic code), the most favorable codons for the stability may be determined (so-called alternative codon usage). Depending on the amino acid to be encoded by the RNA, there are various possibilities for modification of the RNA sequence, compared to its wild type sequence. In particular, codons which contain A and / or U nucleosides may be modified by substituting these codons by other codons, which code for the same amino acids but contain no A and / or U or contain a lower content of A and / or U nucleosides. Thus, in some aspects, G / C content of a coding region of an RNA described herein is increased by at least, at most, exactly, or between (inclusive or exclusive) any two of 10%, 20%, 30%, 40%, 50%, 55%, or even more compared to the G / C content of a coding region of a wild type RNA. In some aspects, the coding region of the EBV RNA described herein comprises a G / C content of at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, or at least 80%. In some aspects, the coding region of the EBV RNA described herein comprises a G / C content of or of about 50% to 75%, 55% to 70%, 50% to 60%, 60% to 70%, 70% to 80%, 50% to 55%, 55% to 60%, 60% to 65%, 65% to 70%, 70% to 75%, or 75% to 80%. In some aspects, the coding region of the EBV RNA described herein comprises a G / C content of or of about 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, or 75%. In some aspects, the coding region of the EBV RNA described herein comprises a G / C content of or of about 58%, 66% or 62%.

In other aspects of the present disclosure, the RNA molecules may comprise modified nucleobases that may be incorporated into modified nucleosides and nucleotides. In some aspects, the RNA molecule may include one or more modified nucleotides. The terms "modification" and "modified", in regard to nucleic acids, refer to modification with respect to adenosine (A), guanosine (G), uridine (U), thymidine (T) and / or cytidine (C) ribonucleosides and / or deoxyribonucleosides in at least one of their position, pattern, percent and / or population. Such modified nucleotides and nucleosides can be naturally occurring modified nucleotides and nucleosides and / or non-naturally occurring modified nucleotides and nucleosides. Such modifications can include those at the sugar, backbone, and / or nucleobase portion of the nucleotide and / or nucleoside as are recognized in the art. Non-limiting examples of such naturally occurring modified nucleotides and nucleotides can be found, inter alia, in the widely recognized MODOMICS database. Non-limiting examples of such non-naturally occurring modified nucleotides and nucleosides can be found, inter alia, in published US application Nos. PCT / US2012 / 058519; PCT / US2013 / 075177; PCT / US2014 / 058897; PCT / US2014 / 058891; PCT / US2014 / 070413; PCT / US2015 / 36773; PCT / US2015 / 36759; and PCT / US2015 / 36771; or published international application No. PCT / IB2017 / 051367, all of which are incorporated by reference herein. Hence, RNA molecules of the disclosure can comprise standard nucleotides and nucleosides, naturally occurring nucleotides and nucleosides, non-naturally-occurring nucleotides and nucleosides, or any combination thereof. RNA molecules, in some aspects, comprise various (more than one) different types of standard and / or modified nucleotides and nucleosides. In some aspects, a particular region of a nucleic acid contains one, two or more (optionally different) types of standard and / or modified nucleotides and nucleosides. Modifications of RNA molecules include, without limitation, those described herein, and include, but are expressly not limited to, those modifications that comprise chemical modifications. RNA molecules may comprise modifications that are naturally-occurring or non- naturally-occurring, or the RNA molecule may comprise a combination of naturally-occurring and non-naturally-occurring modifications. RNA molecules may comprise non-natural modified nucleotides introduced during synthesis and / or post-synthesis of the RNA molecules to achieve desired functions and / or properties. The modification may be introduced with chemical synthesis or with a polymerase enzyme at the terminal of a chain or anywhere else in the chain. Any of the regions of a polynucleotide may be chemically modified. RNA molecules may include any useful modification, for example, of a sugar, a nucleobase, and / or an inter-nucleoside linkage (e.g., to a linking phosphate, to a phosphodiester linkage and / or to the phosphodiester backbone). The present disclosure provides for modified nucleosides and nucleotides of a nucleic acid (e.g., RNA nucleic acids, such as mRNA nucleic acids). A “nucleoside” refers to a compound containing a sugar molecule (e.g., a pentose or ribose) or a derivative thereof in combination with an organic base (e.g., a purine or pyrimidine) or a derivative thereof (also referred to herein as “nucleobase”). A “nucleotide” refers to a nucleoside, including a phosphate group. Modified nucleotides may by synthesized by any useful method, such as, for example, chemically, enzymatically, and / or recombinantly, to include one or more modified and / or non-natural nucleosides. Nucleic acids can comprise a region or regions of linked nucleosides. Such regions may have variable backbone linkages. The linkages can be standard phosphodiester linkages, in which case the nucleic acids would comprise regions of nucleotides. Modified nucleotide base pairing encompasses not only the standard adenosine- thymine, adenosine-uracil, and / or guanosine-cytosine base pairs, but also base pairs formed between nucleotides and / or modified nucleotides comprising non-standard and / or modified bases, wherein the arrangement of hydrogen bond donors and hydrogen bond acceptors permits hydrogen bonding between a non-standard base and a standard base and / or between two complementary non-standard base structures, such as, for example, in those polynucleotides having at least one chemical modification. One example of such non-standard base pairing is the base pairing between the modified nucleotide inosine and adenine, cytosine or uracil. Any combination of base / sugar and / or linker may be incorporated into RNA molecules of the present disclosure. In some aspects, the RNA molecule may include a modified nucleotide. Non-limiting examples of modified nucleotides that may be included in the RNA molecule include pseudouridine, N1-methylpseudouridine, 5-methyluridine, 3-methyl-uridine, 5-methoxy- uridine, 5-aza-uridine, 6-aza-uridine, 2-thio-5-aza-uridine, 2-thio-uridine, 4-thio-uridine, 4-thio- pseudouridine, 2-thio-pseudouridine, 5-hydroxy-uridine, 5-aminoallyl-uridine, 5-halo-uridine (e.g., 5-iodo-uridine or 5-bromo-uridine), uridine 5-oxyacetic acid, uridine 5-oxyacetic acid methyl ester, 5-carboxymethyl-uridine, 1-carboxymethyl-pseudouridine, 5-carboxy hydroxymethyl-uridine, 5-carboxy hydroxy methyl-uridine methyl ester, 5- methoxycarbonylmethyl-uridine, 5-methoxycarbonylmethyl-2-thio-uridine, 5-aminomethyl-2- thio-uridine, 5-methylaminomethyl-uridine, 1-ethyl-pseudouridine, 5-methylaminomethyl-2- thio-uridine, 5-methylaminomethyl-2-seleno-uridine, 5-carbamoylmethyl-uridine, 5- carboxymethylaminomethyl-uridine, 5-carboxymethylaminomethyl-2-thio-uridine, 5-propynyl- uridine, 1-propynyl-pseudouridine, 5-taurinomethyl-uridine, 1-taurinomethyl-pseudouridine, 5- taurinomethyl-2-thio-uridine, 1-taurinomethyl-4-thio-pseudouridine, 5-methyl-2-thio-uridine, 1- methyl-4-thio-pseudouridine, 4-thio-1-methyl-pseudouridine, 3-methyl-1-pseudouridine, 2- thio-1-methyl-pseudouridine, 1-methyl-1-deaza-pseudouridine, 2-thio-1-methyl-1-deaza- pseudouridine, dihydrouridine, dihydropseudouridine, 5,6-dihydrouridine, 5-methyl- dihydrouridine, 2-thio-dihydrouridine, 2-thio-dihydropseudouridine, 2-methoxy-uridine, 2- methoxy-4-thio-uridine, 4-methoxy-pseudouridine, 4-methoxy-2-thio-pseudouridine, N1- methyl-pseudouridine, 3-(3-amino-3-carboxypropyl)uridine, 1-methyl-3-(3-amino-3- carboxypropyl)pseudouridine, 5-(isopentenylaminomethyl)uridine, 5- (isopentenylaminomethyl)-2-thio-uridine, a-thio-uridine, 2′-O-methyl-uridine, 5,2′-O-dimethyl- uridine, 2′-O-methyl-pseudouridine, 2-thio-2′-O-methyl-uridine, 5-methoxycarbonylmethyl-2′- O-methyl-uridine, 5-carbamoylmethyl-2′-O-methyl-uridine, 5-carboxymethylaminomethyl-2′- O-methyl-uridine, 3,2′-O-dimethyl-uridine, 5-(isopentenylaminomethyl)-2′-O-methyl-uridine, 1- thio-uridine, deoxythymidine, 2′-F-ara-uridine, 2′-F-uridine, 2′-OH-ara-uridine, 5-(2- carbomethoxyvinyl) uridine, 5-[3-(1-E-propenylamino)uridine, any other modified uridine known in the art, or combinations thereof.

In some aspects, the RNA molecule comprises a nucleic acid sequence having at least one uridine replaced by N1-methylpseudouridine and / or pseudouridine. In some aspects, the RNA molecule comprises a nucleic acid sequence having at least, at most, exactly, or between (inclusive or exclusive) any two of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% of uridines replaced by N1-methylpseudouridine and / or pseudouridine. In some aspects, the RNA molecule comprises a nucleic acid sequence having all uridines replaced by N1-methylpseudouridine and / or pseudouridine.

In some aspects, 1, 2, 3, 4, 5, or more of the foregoing modified guanines can be excluded from the RNA molecules disclosed herein. In some aspects, RNA molecules are uniformly modified (e.g., fully modified, modified throughout the entire sequence) for a particular modification. In some aspects, the RNA molecules may be partially or fully (e.g., uniformly) modified along the entire length of the molecule. For example, one or more or all or a given type of nucleotide (e.g., purine and / or pyrimidine, or any one or more or all of A, G, U, C) may be uniformly modified in a polynucleotide of the disclosure, or in a given predetermined sequence region thereof. In some aspects, all nucleotides X in a polynucleotide of the present disclosure (or in a given sequence region thereof) are modified nucleotides, wherein X may be any one of nucleotides A, G, U, C, and / or any one of the combinations A+G, A+U, A+C, G+U, G+C, U+C, A+G+U, A+G+C, G+U+C and / or A+G+C. For example, a polynucleotide can be uniformly modified with pseudouridine, meaning that all uridine residues in the RNA sequence are replaced with pseudouridine. Similarly, a polynucleotide can be uniformly modified for any type of nucleoside residue present in the sequence by replacement with a modified residue such as those set forth above. The modified nucleotide can be replaced by a compound having a single unique structure, or can be replaced by a plurality of compounds having different structures (e.g., 2, 3, 4, or more unique structures). The RNA molecules may contain from or from about 1% to 100% modified nucleotides (either in relation to overall nucleotide content, or in relation to one or more types of nucleotide, e.g., any one or more of A, G, U and / or C) (e.g., at least, at most, exactly, or between (inclusive or exclusive) any two of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100%) or any intervening percentage (e.g., from 1% to 20%, from 1% to 25%, from 1% to 50%, from 1% to 60%, from 1% to 70%, from 1% to 80%, from 1% to 90%, from 1% to 95%, from 10% to 20%, from 10% to 25%, from 10% to 50%, from 10% to 60%, from 10% to 70%, from 10% to 80%, from 10% to 90%, from 10% to 95%, from 10% to 100%, from 20% to 25%, from 20% to 50%, from 20% to 60%, from 20% to 70%, from 20% to 80%, from 20% to 90%, from 20% to 95%, from 20% to 100%, from 50% to 60%, from 50% to 70%, from 50% to 80%, from 50% to 90%, from 50% to 95%, from 50% to 100%, from 70% to 80%, from 70% to 90%, from 70% to 95%, from 70% to 100%, from 80% to 90%, from 80% to 95%, from 80% to 100%, from 90% to 95%, from 90%) to 100%), and from 95% to 100%). It will be understood that any remaining percentage is accounted for by the presence of unmodified A, G, U, and / or C. In some aspects, the RNA molecule may include phosphoramidate, phosphorothioate, and / or methylphosphonate linkages. In some aspects, the RNA molecules may include one or more structural and / or chemical modifications and / or alterations which impart useful properties to the polynucleotide including, in some aspects, reduced degradation in the cell or organism and / or lack of a substantial induction of the innate immune response of a cell into which the RNA molecule is introduced. As used herein, a “structural” feature or modification is one in which two or more linked nucleotides are inserted, deleted, duplicated, inverted and / or randomized in an RNA molecule without significant chemical modification to the nucleotides themselves. Because chemical bonds will necessarily be broken and reformed to affect a structural modification, structural modifications are of a chemical nature and hence are chemical modifications. However, structural modifications will result in a different sequence of nucleotides. For example, the polynucleotide “ATCG” may be chemically modified to “AT-5meC-G”. The same polynucleotide may be structurally modified from “ATCG” to “ATCCCG”. Here, the dinucleotide “CC” has been inserted, resulting in a structural modification to the polynucleotide. In some aspects, a modified RNA molecule, introduced to a cell or organism, exhibits reduced degradation in the cell or organism, respectively, relative to an unmodified nucleic acid comprising standard nucleotides and nucleosides. In some aspects, a modified RNA molecule, introduced into a cell or organism, may exhibit reduced immunogenicity in the cell or organism, respectively (e.g., a reduced innate response) relative to an unmodified nucleic acid comprising standard nucleotides and nucleosides. In some aspects, the RNA molecule may include one or more modified nucleotides in addition to any 5′ cap structure. In some aspects, the RNA molecule does not include modified nucleotides, e.g., does not include modified nucleobases, and all of the nucleotides in the RNA molecule are conventional standard ribonucleotides A, U, G and C, with the exception of an optional 5′ cap that may include, for example, 7-methylguanosine, which is further described below. In some aspects, the RNA may include a 5′ cap comprising a 7’-methylguanosine, and the first 1, 2, or 35′ ribonucleotides may be methylated at the 2’ position of the ribose. B.5′ CAP In some aspects, the RNA molecules described herein include a 5′ cap which generally “caps” the 5′ end of the RNA and stabilizes the RNA molecule. In some aspects, the 5′ cap moiety is a natural 5′ cap. A “natural 5′ cap” is defined as a cap that includes 7-methylguanosine connected to the 5′ end of an mRNA molecule through a 5′ to 5′ triphosphate linkage. In some aspects, a guanosine nucleoside included in a 5′ cap may be modified, for example, by methylation at one or more positions (e.g., at the 7-position) on a base (guanine), and / or by methylation at one or more positions of a ribose. In some aspects, a guanosine nucleoside included in a 5′ cap comprises a 3′O methylation at a ribose (3′OMeG). In some aspects, a guanosine nucleoside included in a 5′ cap comprises methylation at the 7-position of guanine (m7G). In some aspects, a guanosine nucleoside included in a 5′ cap comprises methylation at the 7-position of guanine and a 3′O methylation at a ribose (m7(3′OMeG)). The 5′ cap may be incorporated during RNA synthesis (e.g., co- transcriptional capping) or may be enzymatically engineered after RNA transcription (e.g., post-transcriptional capping). In some aspects, co-transcriptional capping with a cap disclosed herein improves the capping efficiency of an RNA compared to co-transcriptional capping with an appropriate reference 5′ cap. In some aspects, improving capping efficiency may increase the translation efficiency and / or translation rate of an RNA and / or increase expression of an encoded polypeptide. In some aspects, capping is performed after purification, e.g., tangential flow filtration, of the RNA molecule. In some aspects, an RNA described herein comprises a 5′ cap or a 5′ cap analog, e.g., a Cap 0, a Cap 1 or a Cap 2. In some aspects, a provided RNA does not have uncapped 5′- triphosphates. In some aspects, the 5′ end of the RNA is capped with a modified ribonucleotide. In some aspects, the 5′ cap moiety is a 5′ cap analog. In some aspects, an RNA may be capped with a 5′ cap analog. Cap structures include, but are not limited to,7mG(5′)ppp(5′)N1pN2p (Cap 0),7mG(5′)ppp(5′)N1mpNp (Cap 1), and7mG(5′)ppp(5′)N1mpN2mp (Cap 2). In some aspects, 1, 2, 3, 4, 5, or more of the foregoing cap structures can be excluded from the RNA molecules disclosed herein. In some aspects, an RNA described herein comprises a Cap 0. In some aspects, Cap 0 is a N7-methyl guanosine, and a Cap 0 structure comprises a guanosine nucleoside methylated at the 7-position of guanine (m7G). In some aspects, a Cap 0 structure is connected to an RNA via a 5′ to 5′-triphosphate linkage and is also referred to herein as m7G, m7Gppp, and / or m7G(5′)ppp(5′).·A 5′ cap may be methylated with the structure7mG(5′)ppp(5′)N1pN2p (Cap 0) or a derivative thereof, wherein N is the terminal 5′ nucleotide of the nucleic acid carrying the 5′ cap, typically the 5′-end of an mRNA. An exemplary enzymatic reaction for capping may include use of Vaccinia Virus Capping Enzyme (VCE) that includes mRNA triphosphatase, guanylyl-transferase and guanine-7-methytransferase, which catalyzes the construction of N7-monomethylated Cap 0 structures. Cap 0 structures play an important role in maintaining the stability and translational efficacy of the RNA molecule. In the cell, the Cap 0 structure is essential for efficient translation of the mRNA that carries the cap. In some aspects, an RNA described herein comprises a Cap 1, e.g., as described herein. The 5′ cap of the RNA molecule may be further modified on the 2′O position by a 2′- O-methyltransferase, which results in the generation of a Cap 1 structure (m7Gppp [m2′-Ο] N), which may further increase translation efficacy. In some aspects, a Cap 1 structure comprises a guanosine nucleoside methylated at the 7-position of guanine (m7G) and a 2′O methylated first nucleotide in an RNA (2′OMeN1). In some aspects, a Cap 1 structure is connected to an RNA via a 5′- to 5′-triphosphate linkage and is also referred to herein as m7GpppNm, wherein Nmdenotes any nucleotide with a 2′O methylation,7mG(5′)ppp(5′)N1mpNp, m7Gppp(2′OMeN1), and / or m7G(5′)ppp(5′)(2′OMeN1). In some aspects, N1is chosen from A, C, G, or U. In some aspects, N1is A. In some aspects, N1is C. In some aspects, N1is G. In some aspects, N1is U. In some aspects, a m7G(5′)ppp(5′)(2′OMeN1) Cap 1 structure comprises a second nucleotide, N2, which is a cap proximal nucleotide at position 2 and is chosen from A, G, C, or U (m7G(5′)ppp(5′)(2′OMeN1)N2). In some aspects, N2is A. In some aspects, N2is C. In some aspects, N2is G. In some aspects, N2is U. In some aspects, a Cap 1 structure comprises a guanosine nucleoside methylated at the 7-position of guanine (m7G) and one or more additional modifications, e.g., methylation on a ribose, and a 2′O methylated first nucleotide in an RNA. In some aspects, a Cap 1 structure comprises a guanosine nucleoside methylated at the 7-position of guanine, a 3′O methylation at a ribose (m7(3′OMeG)), and a 2′O methylated first nucleotide in an RNA (2′OMeN1). In some aspects, a Cap 1 structure is connected to an RNA via a 5′- to 5′- triphosphate linkage and is also referred to herein as m7(3′OMeG)ppp(2′OMeN1) and / or m7(3′OMeG)(5′)ppp(5′)(2′OMeN1). In some aspects, N1is chosen from A, C, G, or U. In some aspects, N1is A. In some aspects, N1is C. In some aspects, N1is G. In some aspects, N1is U. In some aspects, a m7(3′OMeG)(5′)ppp(5′)(2′OMeN1) Cap 1 structure comprises a second nucleotide, N2, which is a cap proximal nucleotide at position 2 and is chosen from A, G, C, or U (m7(3′OMeG)(5′)ppp(5′)(2′OmeN1)N2). In some aspects, N2is A. In some aspects, N2is C. In some aspects, N2is G. In some aspects, N2is U. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing Cap 1 structures can be excluded from the RNA molecules disclosed herein. In some aspects, a second nucleotide in a Cap 1 structure may comprise one or more modifications, e.g., methylation. In some aspects, an RNA described herein comprises a Cap 2. In some aspects, a Cap 1 structure comprising a second nucleotide comprising a 2′O methylation is a Cap 2 structure. In some aspects, the RNA molecule may be enzymatically capped at the 5′ end using Vaccinia guanylyltransferase, guanosine triphosphate, and S-adenosyl-L-methionine to yield Cap 0 structure. An inverted 7-methylguanosine cap is added via a 5′ to 5′ triphosphate bridge. Alternatively, use of a 2′O-methyltransferase with Vaccinia guanylyltransferase yields the Cap 1 structure where, in addition to the Cap 0 structure, the 2′OH group is methylated on the penultimate nucleotide. S-adenosyl-L-methionine (SAM) is a cofactor utilized as a methyl transfer reagent. Non-limiting examples of 5′ cap structures are those which, among other things, have enhanced binding of cap-binding polypeptides, increased half-life, reduced susceptibility to 5′ endonucleases and / or reduced 5′ decapping, as compared to synthetic 5′ cap structures known in the art (or to a wild type, natural or physiological 5′ cap structure). For example, recombinant Vaccinia Virus Capping Enzyme and recombinant 2′ O- methyltransferase enzyme may create a canonical 5′-5′-triphosphate linkage between the 5′- terminal nucleotide of an mRNA and a guanine cap nucleotide wherein the cap guanine includes an N7 methylation and the 5′-terminal nucleotide of the mRNA includes a 2′-O-methyl. Such a structure is termed the Cap 1 structure. This cap results in a higher translational- competency and cellular stability and a reduced activation of cellular pro-inflammatory cytokines, as compared, e.g., to other 5′ cap analog structures known in the art. A cap species may include one or more modified nucleosides and / or linker moieties. For example, a cap may include a guanine nucleotide and a guanine (G) nucleotide methylated at the 7 position joined by a triphosphate linkage at their 5′ positions, e.g., m7G(5′)ppp(5′)G, commonly written as m7GpppG. A cap species may also be an anti-reverse cap analog. A non-limiting list of possible cap species includes m7GpppG, m7Gpppm7G, m73′dGpppG, m27,O3′GpppG, m27,O3′GppppG, m27,O2′GppppG, m7Gpppm7G, m73′dGpppG, m27,O3′GpppG, m27,O3′GppppG, and m27,O2′GppppG. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing cap species can be excluded from the RNA molecules disclosed herein. In some aspects, the 5′ terminal cap includes a cap analog, for example, a 5′ terminal cap may include a guanine analog. Exemplary guanine analogs include, but are not limited to, inosine, N1-methyl-guanosine, 2′-fluoro-guanosine, 7-deaza-guanosine, 8-oxo-guanosine, 2- amino-guanosine, LNA-guanosine, and 2-azido-guanosine. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing guanine analogs can be excluded from the cap structures disclosed herein. In some aspects, the capping region may include a single cap or a series of nucleotides forming the cap. In this aspect the capping region may be from 1 to 10, e.g., 2-9, 3-8, 4-7, 1- 5, 5-10, or at least 2, or 10 or fewer nucleotides in length. In this aspect, the capping region is at least, at most, exactly, or between (inclusive or exclusive) any two of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides in length. In some aspects, the cap is absent. In some aspects, the first and second operational regions may range from 3 to 40, e.g., 5-30, 10-20, 15, or at least 4, or 30 or fewer nucleotides in length and may comprise, in addition to a Start and / or Stop codon, one or more signal and / or restriction sequences. In some aspects, the first and second operational regions are at least, at most, exactly, or between (inclusive or exclusive) any two of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, or 40 nucleotides in length and may comprise, in addition to a Start and / or Stop codon, one or more signal and / or restriction sequences. Further examples of 5′ cap structures include, but are not limited to, glyceryl, inverted deoxy abasic residue (moiety), 4′, 5′ methylene nucleotide, 1-(beta-D-erythrofuranosyl) nucleotide, 4′-thio nucleotide, carbocyclic nucleotide, 1,5-anhydrohexitol nucleotide, L- nucleotides, alpha-nucleotide, modified base nucleotide, threo-pentofuranosyl nucleotide, acyclic 3′,4′-seco nucleotide, acyclic 3,4-dihydroxybutyl nucleotide, acyclic 3,5 dihydroxypentyl nucleotide, 3′-3′-inverted nucleotide moiety, 3′-3′-inverted abasic moiety, 3′-2′-inverted nucleotide moiety, 3′-2′-inverted abasic moiety, 1,4-butanediol phosphate, 3′- phosphoramidate, hexylphosphate, aminohexyl phosphate, 3′-phosphate, 3′- phosphorothioate, phosphorodithioate, and / or bridging or non-bridging methylphosphonate moiety. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing 5′ cap structures can be excluded from the RNA molecules disclosed herein. In some aspects, the RNA molecule of the present disclosure comprises at least one 5′ cap structure. In some aspects, the RNA molecule of the present disclosure does not comprise a 5′ cap structure. Numerous synthetic 5' cap analogs have been developed and are known in the art to enhance mRNA stability and translatability (see, e.g., Grudzien-Nogalska, E., Kowalska, J., Su, W., Kuhn, A.N., Slepenkov, S.V., Darynkiewicz, E., Sahin, U., Jemielity, J., and Rhoads, R.E., Synthetic mRNAs with superior translation and stability properties in Synthetic Messenger RNA and Cell Metabolism Modulation in Methods in Molecular Biology 69 (Rabinovich, P.H. Ed), 2013). In one aspect, the 5′ capping structure comprises a modified 5′ Cap 1 structure (m7G+m3′-5′-ppp-5′-Am). In one aspect, the 5′ capping structure comprises (3′OMe)-m27,3′-OGppp(m12’-O)ApG (TriLink BioTechnologies). This molecule is identical to the natural RNA cap structure in that it starts with a guanosine methylated at N7 and is linked by a 5′ to 5′ triphosphate linkage to the first coded nucleotide of the transcribed RNA (in this case, an adenosine). This guanosine is also methylated at the 3′ hydroxyl of the ribose to mitigate possible reverse incorporation of the cap molecule. The 2’ hydroxyl of the ribose on the adenosine is methylated, conferring a Cap 1 structure. C. UNTRANSLATED REGIONS (UTRS) The 5′ UTR is a regulatory region situated at the 5′ end of a protein open reading frame that is transcribed into mRNA but not translated into an amino acid sequence and / or to the corresponding region in an RNA polynucleotide, such as an mRNA molecule. An untranslated region (UTR) may be present 5′ (upstream) of an open reading frame (5′ UTR) and / or 3′ (downstream) of an open reading frame (3′ UTR). In some aspects, the UTR is derived from an mRNA that is naturally abundant in a specific tissue (e.g., lymphoid tissue), to which the mRNA expression is targeted. In some aspects, the UTR increases protein synthesis. Without being bound by mechanism or theory, the UTR may increase protein synthesis by increasing the time that the mRNA remains in translating polysomes (message stability) and / or the rate at which ribosomes initiate translation on the message (message translation efficiency). Accordingly, the UTR sequence may prolong protein synthesis in a tissue-specific manner. In some aspects, the regulatory features of a UTR can be incorporated into the RNAs of the present disclosure to, among other things, enhance the stability of the molecule. The specific features can also be incorporated to ensure controlled down-regulation of the transcript in case they are misdirected to undesired organs sites. A variety of 5′ UTR and the 3′ UTR sequences are known and available in the art. It should be understood that any UTR from any gene may be incorporated into the regions of the RNAs of the present disclosure. Furthermore, multiple wild-type UTRs of any known gene may be utilized. It is also within the scope of the present disclosure to provide artificial UTRs which are not variants of wild type regions. These UTRs or portions thereof may be placed in the same orientation as in the transcript from which they were selected or may be altered in orientation and / or location. Hence a 5′ and / or 3′ UTR may be inverted, shortened, lengthened, and / or made with one or more other 5′ UTRs or 3′ UTRs. As used herein, the term “altered” as it relates to a UTR sequence, means that the UTR has been changed in some way in relation to a reference sequence. For example, 5′ UTRs and / or 3′ UTRs may be altered relative to a wild-type or native UTR by the change in orientation and / or location as taught above and / or may be altered by the inclusion of additional nucleotides, deletion of nucleotides, swapping, and / or transposition of nucleotides. Any of these changes produces an “altered” UTR (whether 5′ and / or 3′) including a variant UTR. In some embodiments, a double, triple or quadruple UTR such as a 5′ and / or 3′ UTR may be used. As used herein, a “double” UTR is one in which two copies of the same UTR are encoded either in series or substantially in series. For example, a double beta-globin 3′ UTR may be used. It is also within the scope of the present disclosure to have patterned UTRs. As used herein “patterned UTRs” are those UTRs which reflect a repeating or alternating pattern, such as AB AB AB or AABBAABBAABB or ABCABCABC or variants thereof repeated once, twice, or more than 3 times. In these patterns, each letter, A, B, or C represent a different UTR at the nucleotide level. RNAs may encode polypeptides of interest belonging to a family of proteins that are expressed in a particular cell, tissue and / or at some time during development. In some aspects, the UTRs from any of these genes may be swapped for any other UTR of the same or different family of proteins to create a new RNA molecule. As used herein, a “family of proteins” is used in the broadest sense to refer to a group of two or more polypeptides of interest which share at least one function, structure, feature, localization, origin, and / or expression pattern. In some aspects, the 5′ UTR and the 3′ UTR sequences are computationally derived. In some aspects, the 5′ UTR and the 3′ UTRs are derived from a naturally abundant mRNA in a tissue. The tissue may be, for example, liver, a stem cell and / or lymphoid tissue. The lymphoid tissue may include, for example, any one of a lymphocyte (e.g., a B-lymphocyte, a helper T-lymphocyte, a cytotoxic T-lymphocyte, a regulatory T-lymphocyte, and / or a natural killer cell), a macrophage, a monocyte, a dendritic cell, a neutrophil, an eosinophil and a reticulocyte. In some aspects, the 5′ UTR and the 3′ UTR are derived from an alphavirus. In some aspects, the 5′ UTR and the 3′ UTR are from a wild type alphavirus. In some aspects, untranslated regions may also include translation enhancer elements (TEE).

For example, a chain terminating nucleoside may include those nucleosides deoxygenated at the 2’ and / or 3′ positions of their sugar group. Such species may include 3′ deoxyadenosine (cordycepin), 3′ deoxyuridine, 3′ deoxycytosine, 3′ deoxyguanosine, 3′ deoxythymine, and 2',3′ dideoxynucleosides, such as 2',3′ dideoxyadenosine, 2',3′ dideoxyuridine, 2',3′ dideoxycytosine, 2',3′ dideoxyguanosine, and 2',3′ dideoxythymine. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing chain terminating nucleosides may be excluded from the RNA molecules disclosed herein. In some aspects, incorporation of a chain terminating nucleotide into an mRNA, for example at the 3′-terminus, may result in stabilization of the mRNA, as described, for example, in International Patent Publication No. WO 2013 / 103659. In some aspects of the present disclosure, the RNA molecules additionally include a stem loop, such as a histone stem loop. A stem loop may include 2, 3, 4, 5, 6, 7, 8, or more nucleotide base pairs. For example, a stem loop may include 4, 5, 6, 7, or 8 nucleotide base pairs. A stem loop may be located in any region of an mRNA. For example, a stem loop may be located in, before, or after an untranslated region (a 5′ UTR or a 3′ UTR), a coding region, or a poly-A sequence or tail. In some aspects, a stem loop may affect one or more function(s) of an mRNA, such as initiation of translation, translation efficiency, and / or transcriptional termination. Such histone stem-loop sequences may be histone stem-loop sequences disclosed in WO 2012 / 019780, the disclosure of which is incorporated herein by reference in its entirety. Other non-limiting examples of histone stem loop structures and nucleic acid sequences encoding such structures can be found in, e.g., WO 2016 / 091391, the disclosure of which is incorporated by reference herein in its entirety. In some aspects, the combination of a poly-A sequence or polyadenylation signal and at least one histone stem-loop, even though both represent alternative mechanisms in nature, acts synergistically to increase the protein expression beyond the level observed with either of the individual elements. In some aspects, the synergistic effect of the combination of poly- A and at least one histone stem-loop does not depend on the order of the elements and / or the length of the poly-A sequence. In some aspects, the RNA does not comprise a histone downstream element (HDE). An HDE includes a purine-rich polynucleotide stretch of approximately 15 to 20 nucleotides 3′ of naturally occurring stem-loops, representing the binding site for the U7 snRNA, which is involved in processing of histone pre-mRNA into mature histone mRNA. In some aspects, the histone stem-loop is generally derived from histone genes, and includes an intramolecular base pairing of two neighbored partially or entirely reverse complementary sequences separated by a spacer, consisting of a short sequence, which forms the loop of the structure. The unpaired loop region is typically unable to base pair with either of the stem loop elements. Stability of the stem-loop structure generally depends on the length, number of mismatches or bulges, and / or base composition of the paired region. In some aspects, wobble base pairing (non-Watson-Crick base pairing) may result. In some aspects, the at least one histone stem-loop sequence comprises a length of 15 to 45 nucleotides. In some aspects, the RNA molecules include (e.g., within the 3′ UTR) a poly(C) sequence. In some aspects, the poly-C sequences has at least, at most, exactly, or between (inclusive or exclusive) any two of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, or 200 cytidines. In some aspects, the poly-C sequences has or has about 30 cytidines. In some aspects, the RNA molecules include an internal ribosome entry site (IRES) sequence or IRES-motif. In some aspects, an IRES sequence separates ORFs, e.g., if the RNA encodes two or more peptides or proteins. An IRES-sequence may therefore be useful if the RNA molecule is a bi- or multicistronic nucleic acid molecule. In some aspects, the RNA does not comprise an intron. In some aspects, the RNA may instead or additionally include a microRNA binding site. Representative RNA molecules including a combination of the elements disclosed herein can include, without limitation, in 5′-to-3′-direction, the following: ORF - poly-A sequence; ORF - IRES - ORF - poly-A sequence; ORF - 3′ UTR - poly-A sequence; ORF - poly-A sequence - 3′ UTR; ORF - 3′ UTR - poly-A sequence - poly(C) sequence - histone stem-loop; ORF - 3′ UTR - poly-A sequence - poly(C) sequence - poly-A sequence; ORF - 3′ UTR - poly-A sequence - histone stem-loop - poly-A sequence; 5′ UTR - ORF - 3′ UTR; 5′ UTR - ORF - poly-A sequence; 5′ UTR - ORF - poly-A sequence - poly(C) sequence - histone stem-loop; 5′ UTR - ORF - poly-A sequence - poly(C) sequence - poly-A sequence; 5′ UTR - ORF - poly-A sequence - histone stem-loop - poly-A sequence; 5′ UTR - ORF - 3′ UTR - poly-A sequence; 5′ UTR - ORF - 3′ UTR - poly-A sequence - poly(C) sequence 5′ UTR - ORF - 3′ UTR - poly-A sequence - poly(C) sequence - histone stem- loop; 5′-cap - 5′ UTR - ORF - 3′ UTR; 5′-cap - 5′ UTR - ORF - poly-A sequence; 5′-cap - 5′ UTR - ORF - 3′ UTR - poly-A sequence; 5′-cap - 5′ UTR - ORF - 3′ UTR - poly-A sequence - poly(C) sequence; or 5′-cap - 5′ UTR - ORF - 3′ UTR - poly-A sequence - poly(C) sequence - histone stem- loop. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing elements may be excluded from the RNA molecules disclosed herein. H. SELF-AMPLIFYING RNA (saRNA) In some aspects, the RNA molecule may be an saRNA. “Self-amplifying RNA,” “saRNA,” and “replicon” refer to RNA with the ability to replicate itself. Self-amplifying RNA molecules may be produced by using replication elements derived from, e.g., alphaviruses, and substituting the structural viral polypeptides with a nucleotide sequence encoding a polypeptide of interest. A self-amplifying RNA molecule is typically a positive-strand molecule that may be directly translated after delivery to a cell, and this translation provides an RNA- dependent RNA polymerase that then produces both antisense and sense transcripts from the delivered RNA. The delivered RNA leads to the production of multiple daughter RNA molecules. These daughter RNA molecules, as well as collinear subgenomic transcripts, may be translated themselves to provide in situ expression of an encoded gene of interest, e.g., a viral antigen, and / or may be transcribed to provide further transcripts with the same sense as the delivered RNA that are translated to provide in situ expression of the antigen. The overall result of this sequence of transcriptions is an amplification in the number of the introduced saRNA molecules, and consequently, the encoded gene of interest, e.g., a viral antigen, becomes a major polypeptide product of the cells. In some aspects, the self-amplifying RNA includes at least one or more genes including any one of viral replicases, viral proteases, viral helicases and other nonstructural viral proteins, or combination thereof. In some aspects, 1, 2, 3, or more of the foregoing genes may be excluded from the self-amplifying RNA molecules disclosed herein. In some aspects, the self-amplifying RNA may also include 5′- and 3′-end tractive replication sequences, and optionally a heterologous sequence that encodes a desired amino acid sequence (e.g., an antigen of interest). A subgenomic promoter that directs expression of the heterologous sequence may be included in the self-amplifying RNA. Optionally, the heterologous sequence (e.g., an antigen of interest) may be fused in frame to other coding regions in the self- amplifying RNA and / or may be under the control of an internal ribosome entry site (IRES). In some aspects, a self-amplifying RNA molecule described herein encodes (i) an RNA-dependent RNA polymerase that may transcribe RNA from the self-amplifying RNA molecule and (ii) a polypeptide of interest, e.g., an EBV antigen as disclosed herein. In some aspects, the polymerase may be an alphavirus replicase, e.g., including any one of alphavirus proteins nsP1, nsP2, nsP3, nsP4, or any combination thereof. In some aspects, 1, 2, 3, or more of the foregoing alphavirus proteins may be excluded from the RNA molecules disclosed herein. In some aspects, the self-amplifying RNA molecule may have two open reading frames. The first (5′) open reading frame may encode a replicase; the second (3′) open reading frame may encode a polypeptide comprising an antigen of interest. In some aspects the RNA may have additional (e.g., downstream) open reading frames, e.g., to encode further antigens or to encode accessory polypeptides. In some aspects, the saRNA molecule further includes (1) an alphavirus 5′ replication recognition sequence, and (2) an alphavirus 3′ replication recognition sequence. In some aspects, the 5′ sequence of the self-amplifying RNA molecule is selected to ensure compatibility with the encoded replicase. In some aspects, the self-amplifying RNA molecule may encode a single polypeptide antigen or, optionally, two or more polypeptide antigens linked together in a way that each of the sequences retains its identity (e.g., linked in series) when expressed as an amino acid sequence. The polypeptides generated from the self-amplifying RNA may then be produced as a fusion polypeptide or engineered in such a manner to result in separate polypeptide or peptide sequences. In some aspects, the self-amplifying RNA described herein may encode one or more polypeptide antigens that include a range of epitopes. In some aspects, the self-amplifying RNA described herein may encode epitopes capable of eliciting either a helper T cell response or a cytotoxic T cell response or both. IV. RNA TRANSCRIPTION In some aspects, the RNA disclosed herein is produced by in vitro transcription or chemical synthesis. In the context of the present disclosure, the term “transcription” relates to a process, wherein the genetic code in a DNA sequence is transcribed into RNA. Subsequently, the RNA may be translated into peptide or protein. According to the present disclosure, “transcription” comprises “in vitro transcription” or “IVT,” which refers to the process whereby transcription occurs in vitro in a non-cellular system to produce a synthetic RNA product for use in various applications, including, e.g., production of protein or polypeptides. The methodology for in vitro transcription of mRNA is well known in the art. (see, e.g., Losick, R. 1972. In vitro transcription, Ann Rev Biochem, 41409-46; Kamakaka, R. T. and Kraus, W. L. 2001. In vitro Transcription, Current Protocols in Cell Biology, 2:11.6:11.6.1-11.6.17; Beckert, B. And Masquida, B.2010. Synthesis of RNA by In vitro Transcription in RNA, Methods in Molecular Biology, 703 (Neilson, H. Ed), New York, N.Y. Humana Press, 2010; Brunelle, J.L. and Green, R., 2013, Chapter Five – In vitro transcription from plasmid or PCR-amplified DNA, Methods in Enzymology 530:101-114; all of which are incorporated herein by reference). Cloning vectors may be applied for the generation of transcripts. These cloning vectors are generally designated as transcription vectors and are according to the present invention encompassed by the term “vector.” According to specific aspects, the RNA used is in vitro transcribed RNA (IVT-RNA) and may be obtained by in vitro transcription of an appropriate DNA template. Template DNA can be prepared for in vitro transcription from a number of sources with appropriate techniques which are well known in the art including, but not limited to, plasmid DNA and polymerase chain reaction amplification (see Linpinsel, J.L and Conn, G.L., General protocols for preparation of plasmid DNA template, and Bowman, J.C., Azizi, B., Lenz, T.K., Ray, P., and Williams, L.D. in RNA in vitro transcription and RNA purification by denaturing PAGE in Recombinant and in vitro RNA syntheses, Methods 941 Conn G.L. (ed), New York, N.Y. Humana Press, 2012, each incorporated herein by reference). The promoter for controlling transcription may be any promoter for any RNA polymerase. Particular examples of RNA polymerases are the T7, T3, and SP6 RNA polymerases. Preferably, the in vitro transcription according to the invention is controlled by a T7 or SP6 promoter. A DNA template for in vitro transcription may be obtained by cloning of a nucleic acid, in particular cDNA, and introducing it into an appropriate vector for in vitro transcription. The cDNA may be obtained by reverse transcription of RNA. Synthetic IVT RNA products may be translated in vitro or introduced directly into cells, where they may be translated. With respect to RNA, the term “expression” or “translation” relates to the process in the ribosomes of a cell by which a strand of mRNA directs the assembly of a sequence of amino acids to make a peptide or protein. Such synthetic RNA products include but are not limited to, e.g., mRNA molecules, saRNA molecules, antisense RNA molecules, shRNA molecules, long non-coding RNA molecules, ribozymes, aptamers, guide RNA molecules (e.g., for CRISPR), ribosomal RNA molecules, small nuclear RNA molecules, small nucleolar RNA molecules, and the like. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing synthetic RNA products may be excluded. An IVT reaction typically utilizes a DNA template (e.g., a linear DNA template) as described and / or utilized herein, ribonucleotides (e.g., non-modified ribonucleotide triphosphates or modified ribonucleotide triphosphates), and an appropriate RNA polymerase. In some aspects, an mRNA is produced by in vitro transcription using a DNA template where DNA refers to a nucleic acid that contains deoxyribonucleotides. In some aspects, an RNA disclosed herein is in vitro transcribed RNA (IVT-RNA) and may be obtained by in vitro transcription of an appropriate DNA template. The promoter for controlling transcription may be any promoter for any RNA polymerase. A DNA template for in vitro transcription may be obtained by cloning of a nucleic acid, in particular cDNA, and introducing it into an appropriate vector for in vitro transcription. The cDNA may be obtained by reverse transcription of RNA. In some aspects, starting material for IVT may include linearized DNA template, nucleotides, Rnase inhibitor, pyrophosphatase, and / or a polymerase (e.g., a T7 RNA polymerase). The nucleotides may be manufactured in house, may be obtained from a supplier, or may be synthesized. The nucleotides may be, but are not limited to, those described herein including natural and unnatural (modified) nucleotides. Any number of RNA polymerases or variants may be used, including, but not limited to, a phage RNA polymerase, e.g., a T7 RNA polymerase, a T3 RNA polymerase, a SP6 RNA polymerase, and / or mutant polymerases such as, but not limited to, polymerases able to incorporate modified nucleic acids and / or modified nucleotides, including chemically modified nucleic acids and / or nucleotides. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing RNA polymerases may be excluded from. Some embodiments exclude the use of Dnase. In some aspects, the IVT process is conducted in a bioreactor. The bioreactor may comprise a mixer. In some aspects, nucleotides may be added into the bioreactor throughout the IVT process. In some aspects, one or more post-IVT agents are added into the IVT mixture comprising RNA in the bioreactor after the IVT process. Exemplary post-IVT agents may include DNAse I configured to digest the linearized DNA template and / or proteinase K configured to digest DNAse I and T7 RNA polymerase. In some aspects, the post-IVT agents are incubated with the mixture in the bioreactor after IVT. In some aspects, the bioreactor may contain at least, at most, exactly, or between (inclusive or exclusive) any two of 60, 70, 80, 90, 100, 110, 120, 130, 140, 150 ,160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, and 500 or more liters IVT mixture. The IVT mixture may have an RNA concentration that is or is not at least, at most, exactly, or between (inclusive or exclusive) any two of 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 7.0, 8.0, 9.0, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mg / mL or more RNA. In some aspects, the IVT mixture may include residual spermidine, residual DNA, residual proteins, peptides, HEPES, EDTA, ammonium sulfate, cations (e.g., Mg2+, Na+, Ca2+), RNA fragments, residual nucleotides, free phosphates, or any combinations thereof. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing can be excluded from the IVT mixture. Isolation and / or purification of the nucleic acids described herein may include, but is not limited to, phenol / chloroform extraction and / or precipitation with either alcohol (ethanol, isopropanol) in the presence of monovalent cations or lithium chloride for nucleic acid clean- up, quality assurance and quality control. Additional, non-limiting examples of purification procedures include AGENCOURT® beads (Beckman Coulter Genomics, Danvers, MA), poly- T beads, LNATM oligo-T capture probes (EXIQON® Inc, Vedbaek, Denmark), HPLC based purification methods such as, but not limited to, strong anion exchange HPLC, weak anion exchange HPLC, reverse phase HPLC (RP-HPLC), and hydrophobic interaction HPLC (HIC- HPLC), size exclusion chromatography, and silica-based affinity chromatography and polyacrylamide gel electrophoresis. Purification can be performed using a variety of commercially available kits including, but not limited to SV Total Isolation System (Promega) and In vitro Transcription Cleanup and Concentration Kit (Norgen Biotek). In some aspects, 1, 2, 3, 4, 5, or more of the foregoing purification may be excluded. The term “purified” when used in relation to a nucleic acid such as a “purified nucleic acid” refers to one that is separated from at least one contaminant. A “contaminant” is any substance that makes another unfit, impure or inferior. Thus, a purified nucleic acid (e.g., DNA and RNA) is present in a form or setting different from that in which it is found in nature, or a form or setting different from that which existed prior to subjecting it to a treatment and / or purification method. In some aspects, at least a portion of the IVT mixture is filtered. The IVT mixture may be filtered via ultrafiltration and / or diafiltration to remove at least some impurities from the IVT mixture and / or to change buffer solution for the at least a portion of IVT mixture to produce a concentrated RNA solution as a retentate. In some aspects, both “ultrafiltration” and “diafiltration” refer to a membrane filtration process. Ultrafiltration typically uses membranes having pore sizes of at least, at most, exactly, or between (inclusive or exclusive) any two of 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, and 0.1 µm. In some aspects, ultrafiltration membranes are typically classified by molecular weight cutoff (MWCO) rather than pore size. For example, the MWCO may be at least, at most, exactly, or between (inclusive or exclusive) any two of 30 kDa, 40 kDa, 50 kDa, 60 kDa, 70 kDa, 80 kDa, 90 kDa, 100 kDa, 110 kDa, 120 kDa, 130 kDa, 140 kDa, 150 kDa, 160 kDa, 170 kDa, 180 kDa, 190 kDa, 200 kDa, 210 kDa, 220 kDa, 230 kDa, 240 kDa, 250 kDa, 260 kDa, 270 kDa, 280 kDa, 290 kDa, 300 kDa, 310 kDa, 320 kDa, 330 kDa, 340 kDa, 350 kDa, 360 kDa, 370 kDa, 380 kDa, 390 kDa, 400 kDa, 500 kDa, 600 kDa, 700 kDa, 800 kDa, 900 kDa, 1000 kDa, 2000 kDa, 3000 kDa, 4000 kDa, 5000 kDa, 6000 kDa, 7000 kDa, 8000 kDa, 9000 kDa, and 10000 kDa. A skilled artisan will understand that filtration membranes may comprise different suitable materials, including, e.g., polymers, cellulose, ceramic, etc., depending upon the application. In some aspects, membrane filtration may be more desirable for large volume purification process. In some aspects, ultrafiltration and diafiltration of the IVT mixture for purifying RNA may include (1) Direct Flow Filtration (DFF), also known as “dead-end” filtration, that applies a feed stream perpendicular to the membrane face and attempts to pass 100% of the fluid through the membrane, and / or (2) Tangential Flow Filtration (TFF), also known as crossflow filtration, where a feed stream passes parallel to the membrane face as one portion passes through the membrane (permeate) while the remainder (retentate) is retained and / or recirculated back to the feed tank. In some aspects, the filtering of the IVT mixture is conducted via TFF comprising an ultrafiltration step, a first diafiltration step, and a second diafiltration step. In some aspects, the first diafiltration step is conducted in the presence of ammonium sulfate. The first diafiltration step may be configured to remove a majority of impurities from the IVT mixture. In some aspects, the second diafiltration step is conducted without ammonium sulfate. The second diafiltration step may be configured to transfer the RNA into a DS buffer formulation. A filtration membrane with an appropriate MWCO may be selected for ultrafiltration in the TFF process. The MWCO of a TFF membrane determines which solutes may pass through the membrane into the filtrate and which are retained in the retentate. The MWCO of a TFF membrane may be selected such that substantially all of the solutes of interest (e.g., desired synthesized RNA species) remain in the retentate, whereas undesired components (e.g., excess ribonucleotides, small nucleic acid fragments such as digested or hydrolyzed DNA template, peptide fragments such as digested proteins and / or other impurities) pass into the filtrate. In some aspects, the retentate comprising desired synthesized RNA species may be re-circulated to a feed reservoir to be re-filtered in additional cycles. In some aspects, a TFF membrane may have a MWCO of at least, at most, exactly, or between (inclusive or exclusive) any two of 30 kDa, 40 kDa, 50 kDa, 60 kDa, 70 kDa, 80 kDa, 90 kDa, or more. In some aspects, a TFF membrane may have a MWCO of at least, at most, exactly, or between (inclusive or exclusive) any two of 100 kDa, 150 kDa, 200 kDa, 250 kDa, 300 kDa, 350 kDa, 400 kDa, or more. In some aspects, a TFF membrane may have a MWCO of or of about 250- 350 kDa. In some aspects, a TFF membrane (e.g., a cellulose-based membrane) may have a MWCO of or of about 30-300 kDa; 50-300 kDa, 100-300 kDa, or 200-300 kDa. Diafiltration may be performed either discontinuously, or alternatively, continuously. For example, in continuous diafiltration, a diafiltration solution may be added to a sample feed reservoir at the same rate as filtrate is generated. In this way, the volume in the sample reservoir remains constant but small molecules (e.g., salts, solvents, etc.) that may freely permeate through a membrane are removed. Using solvent removal as an example, each additional diafiltration volume (DV) reduces the solvent concentration further. In discontinuous diafiltration, a solution is first diluted and then concentrated back to the starting volume. This process is then repeated until the desired concentration of small molecules (e.g., salts, solvents, etc.) remaining in the reservoir is reached. Each additional diafiltration volume (DV) reduces the small molecule (e.g., solvent) concentration further. Continuous diafiltration typically requires a minimum volume for a given reduction of molecules to be filtered. Discontinuous diafiltration, on the other hand, permits fast changes of the retentate condition, such as pH, salt content, and the like. In some aspects, the first diafiltration step is conducted with at least, at most, exactly, or between (inclusive or exclusive) any two of 2, 3, 4, 5, 6, 7, 8, 9, 10, or more diavolumes. In some aspects, the second diafiltration step is conducted with at least, at most, exactly, or between (inclusive or exclusive) any two of 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or more diavolumes. In some aspects, the first diafiltration step is conducted with 5 diavolumes, and second diafiltration step is conducted with 10 diavolumes. In some aspects, for ultrafiltration and / or diafiltration, the IVT mixture is filtered at a rate of at least, at most, exactly, or between (inclusive or exclusive) any two of 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 500, 600, 700, 800, 900, or 1000 L / m2of filter area per hour, or more. The concentrated RNA solution may comprise at least, at most, exactly, or between (inclusive or exclusive) any two of 2.0, 2.1, 2.2, 2.3, 2.4, or 2.5 mg / mL single stranded RNA. The bioburden of the concentrated RNA solution via filtration to obtain an RNA product solution may also be reduced, in some aspects. The filtration for reducing bioburden may be conducted using one or more filters. The one or more filters may include a filter with a pore size that is or is not at least, at most, exactly, or between (inclusive or exclusive) any two of 0.2 µm, 0.45 µm, 0.65 µm, 0.8 µm, or any other pore size configured to remove bioburdens. As one example, reducing the bioburden may include draining a retentate tank containing retentate obtained from the ultrafiltration and / or diafiltration to obtain the retentate. Reducing the bioburden may include flushing a filtration system for ultrafiltration and / or diafiltration using a wash buffer solution to obtain a wash pool solution comprising residue RNA remaining in the filtration system. The retentate may be filtered to obtain a filtered retentate. The wash pool solution may be filtered using a first 0.2 µm filter to obtain a filtered wash pool solution. The retentate may be filtered using the first 0.2 µm filter or another 0.2 µm filter. The filtered wash pool solution and the filtered retentate may be combined to form a combined pool solution. The combined pool solution may be filtered using a second 0.2 µm filter to obtain a filtered combined pool solution, which is further filtered using a third 0.2 µm filter to produce an RNA product solution. A quality assurance and / or quality control check may be conducted using methods such as, but not limited to, gel electrophoresis, UV absorbance, and / or analytical HPLC. In some aspects, the nucleic acids may be sequenced by methods including, but not limited to reverse-transcriptase-PCR. In some aspects, the nucleic acid may be quantified using methods such as, but not limited to, ultraviolet visible spectroscopy (UV / Vis). A non-limiting example of a UV / Vis spectrometer is a NANODROP® spectrometer (ThermoFisher, Waltham, MA). The quantified nucleic acid may be analyzed in order to determine if the nucleic acid may be of proper size and / or to assess degradation. Degradation of the nucleic acid may be assessed by methods such as, but not limited to, agarose gel electrophoresis, HPLC based purification methods such as, but not limited to, strong anion exchange HPLC, weak anion exchange HPLC, reverse phase HPLC (RP-HPLC), and hydrophobic interaction HPLC (HIC- HPLC), liquid chromatography-mass spectrometry (LCMS), capillary electrophoresis (CE) and capillary gel electrophoresis (CGE). In some aspects, 1, 2, 3, 4, 5, or more of the foregoing assessment methods may be excluded. V. RNA ENCAPSULATION The RNA in an RNA product solution may be encapsulated, and the RNA solution may further comprise at least one encapsulating agent. In one aspect, the encapsulating agent comprises a lipid, a lipid nanoparticle (LNP), lipoplexes, polymeric particles, polyplexes, monolithic delivery systems, or a combination thereof. In some aspects, 1, 2, 3, 4, 5, or more of the foregoing elements may be excluded as an encapsulating agent. In one aspect, the encapsulating agent is a lipid, and produced is lipid nanoparticle (LNP)-encapsulated RNA. Without intending to be bound by any theory, it is believed that the cationic or cationically ionizable lipid or lipid-like material and / or the cationic polymer combine together with the nucleic acid to form aggregates, and this aggregation results in colloidally stable particles. A lipid may be a naturally occurring lipid or a synthetic lipid. However, a lipid is usually a biological substance. Biological lipids are well known in the art, and include for example, neutral fats, phospholipids, phosphoglycerides, steroids, terpenes, lysolipids, glycosphingolipids, glucolipids, sulphatides, lipids with ether and ester-linked fatty acids and polymerizable lipids, and combinations thereof. A lipid is a substance that is insoluble in water and extractable with an organic solvent. Compounds other than those specifically described herein are understood by one of skill in the art as lipids and are encompassed by the compositions and methods of the present disclosure. A lipid component and a non-lipid may be attached to one another, either covalently or non-covalently. In some aspects, LNPs may be designed to protect RNA molecules (e.g., saRNA, mRNA) from extracellular Rnases and / or may be engineered for systemic delivery of the RNA to target cells.
