This invention generally relates to immunogenic compositions that comprise an RNA component and a polypeptide component. Immunogenic compositions that deliver antigens in two different forms—a first antigen from a pathogen, in RNA-coded form; and a second antigen from a different pathogen, in polypeptide form—are effective in inducing immune response to both pathogens.

Immunogenic combination compositions and uses thereof

The present application discloses stability-indicating potency assays for influenza vaccines.

Influenza potency assays

Disclosed herein are influenza vaccine compositions, related preparations and intermediates, formulations, production methods, immunization methods, and use thereof, for achieving improved immune-protection in human subjects. More specifically, non-egg-based influenza vaccines are described, which provide improved antigenic match.

Antigenically matched influenza vaccines

The invention generally relates to recombinant human cytomegalovirus (CMV) gB proteins and immunogenic fragments thereof, which do not comprise a transmembrane (TM) domain; and comprise one or more mutations that reduce the aggregation between the monomeric trimers of gB, and/or adhesion of the monomeric trimer of gB to the host cell.

Cytomegalovirus antigens

The invention relates to chimeric norovirus VP1 proteins containing the S-domain of VP1 of a first norovirus strain and a P-domain that contains at least a portion of the P-domain of VP1 of a second norovirus strain. The invention also relates to nucleic acids that encode the chimeric VP1 proteins, virus-like particles that contain a chimeric norovirus VP1 protein, and to immunogenic compositions.

Norovirus derived immunogenic compositions and methods

The present invention relates to the use of rotavirus particles for displaying a heterologous protein, alone or in complex with another molecule. The invention further relates to methods that employ these modified rotavirus particles to rapidly determine the structure of the heterologous protein or the complex using cryo-electron microscopy (cryo-EM). The invention also relates to a method of immunizing a patient, wherein said method comprises administering to the patient the modified rotavirus particles of the invention.

Rotavirus particles with chimeric surface proteins

The present invention is directed to mutant parvovirus VP1 unique region polypeptides, compositions comprising such polypeptides, methods of making such compositions, as well as methods for identifying the likely presence of parvovirus-neutralizing antibodies, and methods for assessing the functional immunogenicity of parvovirus vaccines and measuring a correlate of efficacy to assess a treatment for parvovirus infection.

Parvovirus Vp1 unique region polypeptides and compositions thereof

The invention provides a process for generating parvovirus VP1/VP2 virus like particles (VLPs). The invention further provides methods for purification of the parvovirus VLPs and immunogenic compositions that contain the VLPs. The invention also includes recombinant nucleic acid molecules that encode parvovirus VP1 and VP2, and host cells that contain the recombinant nucleic acids.
