The present invention provides methods and compositions to induce neutralizing antibodies in mammals to serotypes of dengue virus, measles virus, mumps virus, rubella and/or VZV virus.

Recombinant paramyxoviruses including a viral genome encoding a heterologous gene are provided. In several embodiments, the recombinant paramyxovirus is a recombinant parainfluenza virus, such as a recombinant PIV3 including a viral genome encoding a heterologous respiratory syncytial virus F ectodomain linked to the transmembrane domain and the cytoplasmic tail of the F protein from the PIV3. Nucleic acid molecules including the genome of a recombinant paramyxoviruses are also provided. The recombinant viruses may advantageously be used in vaccine formulations, such as for vaccines against parainfluenza virus and respiratory syncytial virus.

The present invention aims at providing a mucosal vaccine composition that can be administered to an intraoral mucous membrane, ocular mucous membrane, ear mucous membrane, genital mucous membrane, pharyngeal mucous membrane, respiratory tract mucous membrane, bronchial mucous membrane, pulmonary mucous membrane, gastric mucous membrane, enteric mucous membrane, or rectal mucous membrane, that is useful as a prophylactic or therapeutic agent for infectious diseases or cancers, and is capable of safely and effectively inducing the systemic immune response and mucosal immune response. The present invention provides a mucosal vaccine composition to be administered to at least one mucous membrane selected from the group consisting of a human or animal intraoral mucous membrane, ocular mucous membrane, ear mucous membrane, genital mucous membrane, pharyngeal mucous membrane, respiratory tract mucous membrane, bronchial mucous membrane, pulmonary mucous membrane, gastric mucous membrane, enteric mucous membrane, and rectal mucous membrane, containing: at least one antigen; and as an adjuvant, a lipopolysaccharide derived from at least one gram-negative bacterium selected from the group consisting of Serratia, Leclercia, Rahnella, Acidicaldus, Acidiphilium, Acidisphaera, Acidocella, Acidomonas, Asaia, Belnapia, Craurococcus, Gluconacetobacter, Gluconobacter, Kozakia, Leahibacter, Muricoccus, Neoasaia, Oleomonas, Paracraurococcus, Rhodopila, Roseococcus, Rubritepida, Saccharibacter, Stella, Swaminathania, Teichococcus, Zavarzinia, Pseudomonas, Achromobacter, Bacillus, Methanoculleus, Methanosarcina, Clostridium, Micrococcus, Flavobacterium, Pantoea, Acetobacter, Zymomonas, Xanthomonas, and Enterobacter, or a salt thereof.

The present invention relates to an attenuated mumps virus and a live vaccine comprising the same. The attenuated mumps virus vaccine of the present invention can be effectively used for additional vaccination to control the occurrence of breakthrough infection and the epidemic of mumps due to differences in genotypes of existing vaccine strains and epidemic strains and decreased immunity.

Recombinant paramyxoviruses including a viral genome encoding a heterologous gene are provided. In several embodiments, the recombinant paramyxovirus is a recombinant parainfluenza virus, such as a recombinant PIV3 including a viral genome encoding a heterologous respiratory syncytial virus F ectodomain linked to the transmembrane domain and the cytoplasmic tail of the F protein from the PIV3. Nucleic acid molecules including the genome of a recombinant paramyxoviruses are also provided. The recombinant viruses may advantageously be used in vaccine formulations, such as for vaccines against parainfluenza virus and respiratory syncytial virus.

The present invention provides a nasal mucosal vaccine composition which is safe, useful as a preventive or therapeutic agent for infectious diseases or cancers, and capable of inducing systemic immune responses and mucosal immune responses effectively. The present invention provides a nasal mucosal vaccine composition to be administered to a human or animal nasal mucous membrane, the nasal mucosal vaccine composition containing at least one antigen excluding antigens derived from influenza viruses; and as an adjuvant, a lipopolysaccharide derived from at least one gram-negative bacterium selected from the group consisting of Serratia, Leclercia, Rahnella, Acidicaldus, Acidiphilium, Acidisphaera, Acidocella, Acidomonas, Asaia, Belnapia, Craurococcus, Gluconacetobacter, Gluconobacter, Kozakia, Leahibacter, Muricoccus, Neoasaia, Oleomonas, Paracraurococcus, Rhodopila, Roseococcus, Rubritepida, Saccharibacter, Stella, Swaminathania, Teichococcus, Zavarzinia, Pseudomonas, Achromobacter, Bacillus, Methanoculleus, Methanosarcina, Clostridium, Micrococcus, Flavobacterium, Pantoea, Acetobacter, Zymomonas, Xanthomonas, and Enterobacter, or a salt thereof.

The present disclosure provides inter alia compositions that comprise therapeutic agents (e.g., live attenuated viral antigens, therapeutic proteins, etc.) and a lipid component. The lipid component may comprise or consist of different types of lipid or lipids as described herein. In some embodiments the therapeutic agents are thermolabile. The present disclosure also provides methods for preparing compositions, including the aforementioned compositions (e.g., melt methods and spray injection methods among others).

The present invention relates to methods and compositions for use in inducing tumor-specific antibody mediated complement-dependent cytotoxic response in an animal having a tumor comprising administering to said animal a composition comprising a replication competent oncolytic virus wherein administration of the composition induces in the animal production of antibodies that mediate a CDC response specific to said tumor.

This document relates to methods and materials for virotherapy. For example, this document provides methods and materials for treating cancer using a recombinant mumps virus as an oncolytic agent.
