1. A method for preventing or for protecting against Neisserial infection in a mammal comprising administering to the mammal an immunogenic composition comprising a fusion polypeptide, wherein the fusion polypeptide comprises a mutant v2 factor H Binding Protein (fHbp) polypeptide and a mutant v3 factor H Binding Protein (fHbp) polypeptide,
(a) wherein the mutant v2 fHbp polypeptide comprises an amino acid sequence having at least 90% sequence identity to SEQ ID NO: 5 and includes an amino acid residue corresponding to residue 32 of SEQ ID NO: 5, wherein the amino acid sequence of the mutant v2 fHbp polypeptide differs from SEQ ID NO: 5 at residue 32 by the substitution S32V, and/or
(b) wherein the mutant v3 fHbp polypeptide comprises an amino acid sequence having at least 90% sequence identity to SEQ ID NO: 17 and includes an amino acid residue corresponding to residue 32 from SEQ ID NO: 17, wherein the amino acid sequence of the mutant v3 fHbp polypeptide differs from SEQ ID NO: 17 at residue 32 by the substitution S32V.
