Peptide fragment of respiratory syncytial virus protein G, immunogenic agent, pharmaceutical composition containing it and preparation method

摘要

A polypeptide useful as an immunogen element and characterised in that it is carried on the peptide sequence between amino acid residues 130-230 of the G protein sequence of the human respiratory syncytial virus of sub-groups A and B, or of the bovine respiratory syncytial virus, or on a sequence at least 80% homologous thereto. An immunogenic agent or pharmaceutical composition containing said polypeptide, and a method for preparing same, are also disclosed.
