IMMUNOGENIC COMPOSITIONS COMPRISING AN ANTIGEN AND A PURIFIED M PROTEIN FROM RESPIRATORY SYNCYTIAL VIRUS

摘要

Methods and compositions for enhancing an immune response to an antigen in a host are provided. Immunogenic composition comprising an antigen and an amount of purified M protein from respiratory syncytial virus are provided in a pre-selected amount to provide an enhanced immune response to said antigen in a host having a pre-existing respiratory syncytial virus M-specific immune response. The antigen can be an antigen from Respiratory syncytial virus.
