Recombinant chimeric bovine/human parainfluenza virus 3 (rB/HPIV3) vectors expressing Respiratory Syncytial Virus (RSV) G protein or a recombinant RSV G protein, as well as methods of their use and manufacture, are provided. The rB/HPIV3 vector comprises a genome comprising a heterologous gene encoding the RSV G protein or the recombinant RSV G protein. Nucleic acid molecules comprising the sequence of the genome or antigenome of the disclosed rB/HPIV3 vectors are also provided. The disclosed rB/HPIV3 vectors can be used, for example, to induce an immune response to RSV and HPIV3 in a subject.

The present disclosure provides methods, uses and compositions and kits for use in inducing an antibody immune response in a human subject. The methods and uses involve administering parenterally a low dose volume of a composition comprising an antigen comprising a B-cell epitope, an amphipathic compound, and a hydrophobic carrier, wherein the low dose volume of the composition is less than 100 μl and induces an antibody immune response to the B-cell epitope in the human subject.

Disclosed are peptides comprising a monomeric Fc fragment of an immunoglobulin recognized by a neonatal receptor (FcRn); a modified pre-fusion respiratory syncytia virus (RSV) F protein; and a trimerization domain. Disclosed are nucleic acid sequences capable of encoding peptides comprising a monomeric Fc fragment of an immunoglobulin recognized by a neonatal receptor (FcRn); a modified pre-fusion respiratory syncytia virus (RSV) F protein; and a trimerization domain. Also disclosed are methods for eliciting a protective immune response against RSV comprising administering to a subject an effective amount of a composition comprising a monomeric Fc fragment of an immunoglobulin recognized by FcRn; a modified pre-fusion RSV F protein; and a trimerization domain, wherein the administering is to a mucosal epithelium.

The present invention is generally related to modified or mutated respiratory syncytial virus fusion (F) proteins and methods for making and using them, including immunogenic compositions such as vaccines for the treatment and/or prevention of RSV infection.

The invention provides adenoviral vectors comprising transgenes encoding Lyssaviral antigens. The vectors can be used to produce vaccines for the prophylaxis, amelioration and treatment of diseases caused by Lyssaviral diseases, e.g., rabies.

The present invention provides a respiratory syncytial virus (RSV) recombinant fusion protein (F protein) in which a polymerization domain derived from a foreign protein is bound to the C terminal of a fusion protein (F protein) lacking a transmembrane domain of a wild-type respiratory syncytial virus (RSV) fusion protein (F protein). The recombinant fusion protein of the present invention is soluble and can retain an F protein trimer. Excellent immune-inducing effects can be expected from the recombinant fusion protein of the present invention, and vaccine composition containing same.

The present invention provides mutant RSV F molecules, such as those that can be, or are stabilized, in a pre-fusion conformation by the introduction of one or more DT cross-links. The present invention also provides methods of making such mutant RSV F molecules, compositions comprising such mutant RSV F molecules, and methods of use of such mutant RSV F molecules, for example in vaccination methods, therapeutic methods, and antibody production methods.

The present disclosure provides vaccine compositions and methods for inducing a systemic immune response and a mucosal immune response, wherein the vaccine compositions comprise an antigen and a hepatitis B core virus-like particle (HBc VLP) as adjuvant. The vaccine compositions are suitable for administration to the mucosa surface of subject, and are effective in eliciting a protective immune response against infection.

The invention provides adenoviral vectors comprising transgenes encoding Lyssaviral antigens. The vectors can be used to produce vaccines for the prophylaxis, amelioration and treatment of diseases caused by Lyssaviral diseases, e.g., rabies.
