Abstract:
The present embodiments provide for an S. aureus (SA) Multiple Antigen Presenting System (MAPS) immunogenic composition comprising an immunogenic polysaccharide which induces an immune response, where at least one S. aureus (SA) peptide or polypeptide antigen is associated to the immunogenic polysaccharide by complementary affinity molecules. In some embodiments, the immunogenic polysaccharide can be an antigenic capsular polysaccharide of a Type 5 or Type 8 from S. aureus, or alternatively, a different immunogenic capsular or noncapsular polysaccharide, and where the protein or peptide SA antigens are indirectly linked via an affinity binding pair. The present SA-MAPS immunogenic compositions can elicit both humoral and cellular immune responses to the immunogenic polysaccharide and one or multiple SA antigens at the same time.
