Patent ID: 7309494

Claim:
An immunogenic peptide derived from the G protein of respiratory syncytial virus (RSV) subgroup A comprising: a first peptide comprising amino acids 140-192, of the G protein of the human RSV subgroup A, wherein the residue at positions 173, 176, 182 and 186 are cysteine, and wherein the C-terminus extending at most to the amino acid residue at position 192 is coupled with the N-terminus of a second peptide comprising amino acids 144-159 of the G protein of RSV subgroup A, wherein the immunogenic peptide exhibits a disulfide bridge connecting cysteine residues 173 and 186 and a second disulfide bridge connecting cysteine residues 176 and 182, and wherein said immunogenic peptide comprises a sequence selected from the group consisting of the sequences set forth in SEQ ID NO:1, SEQ ID NO:2, and SEQ ID NO:3.
