Mutants of the P4 Protein of Nontypable Haemophilus Influenzae with Reduced Enzymatic Activity
A P4 variant protein that has reduced enzymatic activity and that induces antibody to wild-type P4 protein and/or has good bactericidal activity against non-typable H. influenzae (NTHi) is useful as an active component in an immunogenic composition for humans. Methods of using these proteins, and compositions containing them in combination with additional antigens, are also provided.
