Abstract
Immunogenic compositions are provided herein that are useful for inducing an immune response specific against group A streptococcus (GAS). Immunogenic compositions provided herein are multivalent and comprise a plurality of immunogenic peptides or fusion polypeptides comprising the immunogenic peptides that induce an immune response against GAS. The immunogenic compositions provided herein induce an immune response against the GAS serotypes represented by an immunogenic peptide (derived from an M protein or Spa protein) comprised within the immunogenic composition and also induce an immune response against serotypes that are unrepresented by any immunogenic peptide included in the immunogenic composition. Methods for using the compositions for inducing an immune response against GAS and for treating or reducing the likelihood of occurrence of a GAS infection are also provided.
