Respiratory syncytial virus protein g expressed on bacterial membrane

• A method for preparing a peptide or protein, wherein (a) a DNA sequence coding for a heterologous polypeptide on a peptide sequence between amino acid residues 130 and 230 of respiratory syncytial virus protein G, sub-groups A and B, or a peptide sequence at least 80 % homologous thereto, and (b) means enabling the expression of the polypeptide on the bacterial membrane surface, are inserted into a bacterium which is not pathogenic for mammals. The resulting conjugate polypeptide and a live bacterium expressing same, pharmaceutical compositions containing them and their use for preparing a vaccine, as well as a DNA sequence coding for said polypeptide, are also disclosed.
