An improved immune response is achieved in an animal by administering, for example injecting, a cocktail of peptides that are similar to, but different from, a target peptide against which it is desired to create antibodies. The similar peptides preferably have the same peptide sequence as the target peptide, but with one or more amino acids substituted by a chance-selected, random, amino acid from a group of allowable amino acids. The peptides may be present on a multi-branch peptide. |
