The invention provides a method for rescuing a novel measles recombinant coronavirus. The pGEM3Zf (+)-T7RNAP plasmid constructed by the invention can be subjected to in-vitro reverse transcription processing to obtain T7RNA polymerase mRNA (messenger Ribonucleic Acid). The method comprises the following steps: by taking an MRC-5 cell as a cell matrix, co-transfecting the MRC-5 cell by using a pT7-MVEZ-COV2S.B.1.617.2 plasmid constructed by the invention and a helper plasmid in a physical electric shock manner, and simultaneously transfecting T7RNA polymerase mRNA (messenger ribonucleic acid). T7RNA polymerase mRNA translates and expresses T7RNA polymerase in an MRC-5 cell, the T7RNA polymerase further drives a T7 promoter, transcription of a full-length plasmid containing all genetic information of the virus and expression of N, P and L genes are started, virus packaging and proliferation are completed in a host cell, and the paramyxovirus with infection activity is obtained.

The disclosure provides live attenuated measles vectors encoding in their genome one or more heterologous genes encoding Epstein-Barr Virus (EBV) proteins, e.g., gp350, gH, gL, and gp42, and variants thereof, as well as nucleic acid constructs encoding such measles vectors. The disclosure also relates to immunogenic compositions comprising live attenuated measles vectors encoding EBV proteins, immunogenic compositions comprising such measles vectors, and use of such measles vectors and immunogenic compositions to induce an immune response to EBV in subjects.

The application provides a plurality of new therapeutic peptides, which are designed based on the heptad repeat region of a viral spike fusion protein (such as SARS-Cov2, MERS-CoV, or HCov-OC43) or a heptad repeat region in a paramyxovirus (such as Measles, Nipah, or HPIV3)), new therapeutic conjugates that comprising these therapeutic peptides, and methods of using the therapeutic peptide conjugates for the treatment of a condition or disease associated with a viral infection.

Embodiments of immunogens comprising a recombinant Mumps (MuV) F ectodomain trimer stabilized in a prefusion conformation or a recombinant Measles (MeV) F ectodomain trimer stabilized in a prefusion conformation are provided. Also provided are embodiments of immunogens comprising chimeric proteins comprising the recombinant MuV or MeV F ectodomain trimer and one or more MuV HN or MeV H ectodomains. Also disclosed are nucleic acids encoding the immunogens and methods of their production. Methods for inducing an immune response in a subject by administering a disclosed immunogen to the subject are also provided. In some embodiments, the immune response treats or inhibits MuV and / or MeV infection in a subject.
