The invention relates to a recombinant novirhabdovirus expressing a chimeric protein comprising the sequence of an antigen of interest flanked, at the N-terminus, by a signal peptide, and at the C-terminus, by a polypeptide comprising at least one portion of the transmembrane domain of a rhabdovirus G protein. Said recombinant novirhabdovirus can be used especially for inducing an immune response to the antigen of interest.

This document describes a number of different polypeptide sequences, and the nucleic acid sequences encoding such polypeptide sequences, that can be used alone or in combination as universal vaccines against viruses including influenza A or influenza B in humans or influenza in swine.

Respiratory virus vaccine compositions for nasal administration to a mammal comprising a hygroscopic gel-forming material, at least one isolated bioactive respiratory virus immunogen, and an adjuvant, kits, receptacles, uses therefor, and methods of manufacture thereof.

Disclosed are salmon interferon sequences useful as adjuvants in fish vaccines. Also disclosed are fish vaccines utilizing said interferon sequences and methods for prevention of fish infections utilizing these vaccines.

The present invention provides a human dose of an immunogenic composition comprising an antigen or antigenic preparation, in combination with an adjuvant which adjuvant comprises an immunologically active saponin fraction derived from the bark of Quillaja Saponaria Molina presented in the form of a liposome and a lipopolysaccharide wherein said saponin fraction and said lipopolysaccharide are both present in said human dose at a level of below 30 g. The present invention further provides an adjuvant composition in a human dose suitable volume comprising between 1 and 30 g of a lipopolysaccharide and between 1 and 30 g of an immunologically active saponin fraction presented in the form of a liposome.

The present disclosure relates to compositions, methods, mixtures, and kits for detecting the presence of, and for removing, a virus from a product produced in an insect cell. The disclosure also relates to proteins, peptides, polypeptides, drug substances, biological products, vaccine antigens, and virus-like particles that are produced in an insect cell and that are free or substantially free of a virus. The disclosure also relates to compositions, methods, assays, and kits for detecting a rhabdovirus in a sample.

The present disclosure provides methods and compositions for inducing an immune response that confers dual protection against infections by either or both of a rabies virus and a coronavirus, and/or which can be used therapeutically for an existing infection with rabies virus and/or a coronavirus to treat at least one symptom thereof and/or to neutralize or clear the infecting agents. In particular, the present disclosure provides a recombinant rabies virus vector comprising a nucleotide sequence encoding at least one coronavirus immunogenic glycoprotein fragment, as well as pharmaceutical compositions comprising the vaccine vectors.

The present invention relates to the use of the pituitary adenylate cyclase activating peptide (PACAP) as a molecular adjuvant for vaccines. Among other applications, these vaccines may be used in the protection against infectious agents such as viruses, bacteria and ectoparasites affecting mammals, birds and aquatic organisms. The PACAP, combined with a particular antigen, demonstrates its effectiveness as adjuvant increasing the host immune response against that antigen. This type of response can be observed when the vaccine compositions or combinations that include PACAP are administered orally, by injection, or by immersion baths, in case of aquatic organisms.

The present disclosure relates to compositions, methods, mixtures, and kits for detecting the presence of, and for removing, a virus from a product produced in an insect cell. The disclosure also relates to proteins, peptides, polypeptides, drug substances, biological products, vaccine antigens, and virus-like particles that are produced in an insect cell and that are free or substantially free of a virus. The disclosure also relates to compositions, methods, assays, and kits for detecting a rhabdovirus in a sample.

The present application relates to viral sensitizers. More specifically, the present application relates to neddylation-activating enzyme inhibitors, as well as processes for their preparation and methods of using such compounds and compositions as viral sensitizers. The present application includes a method of increasing permissiveness of a cell to a virus or genetic material encoding components of the virus, comprising administering an effective amount of a neddylation-activating enzyme (NAE) inhibitor, or a salt, solvate and/or prodrug thereof, to the cell.
