Abstract: The invention relates to adjuvanted vaccine formulations, in particular influenza vaccines for intranasal delivery. Provided is an adjuvanted influenza vaccine formulation, comprising (i) peptidoglycan microparticles obtained from a Gram-positive bacterium and (ii) at least one influenza virus antigen or antigenic preparation thereof, which antigen or antigenic preparation is not fused or otherwise covalently attached to a proteinaceous peptidoglycan binding moiety.

Abstract: The invention relates to the field of immunology and vaccine development, in particular to the development of vaccines based on native antigen oligomers. Provided is an immunogenic composition in particulate form, comprising oligomers of a surface exposed polypeptide of pathogenic origin or tumor origin, or antigenic part thereof, said oligomers being bound non-covalently to a particulate carrier, and a pharmaceutically acceptable diluent or excipient.

Abstract: The invention relates to the field of vaccines against microbial infections and especially bacterial vaccines, in particular to pneumococcal vaccines. More in particular, the invention relates to means and methods to identify, select and isolate a vaccine component for passive and/or active immunization against a microorganism that can be killed by opsonophagocytic cells. The invention relates to a method to identify an opsonophagocytosis inducing antigen as a vaccine component for immunization against a microorganism. The invention describes three pneumococcal proteins SlrA, IgA1 proteinase, and PsaA, and their use as a vaccine component with or without PpmA. The invention also discloses the use of antibodies against said proteins for passive immunization and diagnosis.

Abstract: The disclosure relates to the areas of immunology and vaccine delivery. More specifically, it relates to a bacterial vaccine delivery technology with built-in immunostimulatory properties which allow the immobilization of any antigen of interest, without prior antigen modification. Provided is an antigen-loaded immunogenic carrier complex comprising at least one bifunctional polypeptide attached to an immunogenic carrier, the bifunctional polypeptide comprising a peptidoglycan binding domain (PBD) through which the polypeptide is attached to the carrier, fused to an antigen binding domain (ABD) to which at least one antigen of interest is bound. Also described is a pharmaceutical (e.g., vaccine) composition comprising an antigen-loaded immunogenic carrier complex.

Abstract: Methods for improving binding of a proteinaceous substance to cell-wall material of a Gram-positive bacterium are disclosed. The proteinaceous substance includes an AcmA cell-wall binding domain, homolog or functional derivative thereof. The method includes treating the cell-wall material with a solution capable of removing a cell-wall component such as a protein, lipoteichoic acid or carbohydrate from the cell-wall material and contacting the proteinaceous substance with the cell-wall material.
