Abstract
Multivalent vaccine comprising peptides from vasoactive intestinal peptide, bombesin, Substance P and epidermal growth factor are described. A method of constructing a multivalent gene for use in various expressions vectors and the protein recombinantly expressed in the prokaryotic expression systems are also described.
