An altered G protein or portion thereof of RSV which retains immunogenicity and which, when incorporated into an immunogenic composition or vaccine and administered to a vertebrate, does not induce enhanced disease (e.g., atypical pulmonary inflammation such as pulmonary eosinophilia) upon subsequent infection with RSV, is disclosed. In a particular embodiment, the altered G protein comprises an alteration in the region from amino acid 184 to amino acid 198. Immunogenic compositions and vaccines comprising the altered RSV G protein, and optionally comprising RSV F protein, are also disclosed. |
