An immunogenic or vaccine composition to induce an immune response or protective immune response against West Nile virus (WNV) in an animal susceptible to WNV. The composition includes a pharmaceutically or veterinarily acceptable vehicle or excipient, and a vector. The vector contains heterologous nucleic acid molecule(s), expresses in vivo in the animal WNV antigen, immunogen or epitope thereof, e.g., WNV E; WNV prM and E; WNV M and E; WNV prM, WNV M and E, WNV polyprotein prM-E, WNV polyprotein M-E, or WNV polyprotein prM-M-E. The composition can contain an adjuvant, such as carbomer. Methods for making and using such a composition, including prime-boost regimes and including as to differential diagnosis, are also contemplated.

The present invention relates to an immunogenic or vaccine composition to induce an immune response or protective immune response against Orbiviruses, more specifically bluetongue virus (BTV) in an animal susceptible to BTV infection. The composition may include a pharmaceutically or veterinarily acceptable vehicle or excipient, and a vector. The vector may contain heterologous nucleic acid molecule(s), expresses in vivo in the animal BTV antigen, immunogen or epitope thereof, e.g., BTV VP2; BTV VP2 and VP5; BTV VP2 and VP5 and VP3 and/or VP7. The composition can contain an adjuvant, such as carbomer. Methods for making and using such a composition, including prime-boost regimes and including as to differential diagnosis, are also contemplated.

These vaccines target H5N1, H1, H3 and other subtypes of influenza and are designed to elicit neutralizing antibodies, as well as cellular immunity. The DNA vaccines express hemagglutinin (HA) or nucleoprotein (NP) proteins from influenza which are codon optimized and/or contain modifications to protease cleavage sites of HA which affect the normal function of the protein. Adenoviral constructs expressing the same inserts have been engineered for prime boost strategies. Protein-based vaccines based on protein production from insect or mammalian cells using foldon trimerization stabilization domains with or without cleavage sites to assist in purification of such proteins have been developed. Another embodiment of this invention is the work with HA pseudotyped lentiviral vectors which would be used to screen for neutralizing antibodies in patients and to screen for diagnostic and therapeutic antivirals such as monoclonal antibodies.

The invention provides reagents and methods for heterologous prime-boost immunization regimens. In particular, the invention provides reagents and methods for use in a paramyxovirus-based prime and adenovirus-based boost immunization system, wherein the immunization induces an immune response to a foreign antigen.

The present invention encompasses NDV vaccines. The vaccine may be a subunit vaccine based on HN of NDV. The NDV HN may be expressed in plants or algae including microalgae. The invention also encompasses recombinant vectors encoding and expressing NDV antigens, epitopes or immunogens which can be used to protect animals against NDV. It encompasses also a vaccination regime compatible with the DIVA strategy, including a prime-boost scheme using viral vector or inactivated vaccines and subunit vaccines.

The present invention relates to the generation of a T cell response against a target antigen using a polypeptide comprising a polyepitope construct as a priming composition in a prime boostregimen.

The present invention is directed to a method for generating an antigen-specific immune response in a subject in general and in particular to administering a priming dose of an immunogenic composition of a recombinant mumps virus (rMuV) that encodes an antigen followed by administering a boosting dose of recombinant vesicular stomatitis virus (rVSV) encoding an antigen.

The present invention provides vaccine compositions for effective induction of both mucosal and systemic immunity to pathogenic Mycobacterium species. Vaccination protocols are provided in which both parenteral and mucosal vaccine formulations are administered to a host. The parenteral and mucosal formulations comprise live, attenuated Mycobacteria.

Provided herein are prime-boost regimens and materials used therein. The prime-boost regimens enhance the immune response to a target antigen. The vaccines used for boost are comprised of recombinant attenuated metabolically active Listeria that encodes an expressible antigen that is cross-reactive with the target antigen. In some examples, the immune response is a cellular immune response.

Disclosed and claimed are methods and compositions and kits for the vaccination or immunization of an animal, such as a mammal, advantageously a bovine, involving a prime-boost regimen.

Therapeutic compositions in solid dose form that comprise a mixture of first amorphous or non-crystalline microparticles comprising a bioactive agent and second amorphous or non-crystalline microparticles that comprise the same or different bioactive agent. The compositions provide a primary pharmacological response (first microparticles) and a second “boosting” effect (second microparticles) produced by releasing the agent over a linger period.

An efficient means of inducing an immune response against human immunodeficiency virus (“HIV”) utilizing specific prime-boost regimes is disclosed. The specific prime-boost regimes employ a heterologous prime-boost protocol wherein recombinant adenoviral and poxvirus vectors comprising exogenous genetic material encoding a common HIV antigen are administered in that order. Vaccines administered into living vertebrate tissue in accordance with the disclosed regimes, preferably a mammalian host such as a human or a non-human mammal of commercial or domestic veterinary importance, express the HIV-1 antigen (e.g., Gag), inducing a cellular immune response which specifically recognizes HIV-1. It is believed that the disclosed prime/boost regime will offer a prophylactic advantage to previously uninfected individuals and/or provide a therapeutic effect by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV-1 infection.

The present invention relates to an immunogenic or vaccine composition to induce an immune response or protective immune response against vesicular stomatitis virus (VSV) in an animal susceptible to VSV. The composition may include a pharmaceutically or veterinarily acceptable vehicle or excipient, and a vector. The vector may contain at least one heterologous nucleic acid molecule(s), expresses in vivo in the animal VSV antigen(s), immunogen(s) or epitope(s) thereof, e.g., VSV G protein and/or VSV N protein and/or VSV M protein. The heterologous nucleic acid molecule(s) may be adjusted to the vector/mammalian cell system by codon optimization. The composition can contain an adjuvant, such as carbomer. Methods for making and using such a composition, including prime-boost regimes and including as to differential diagnosis, are also contemplated.
