The methods comprise administering to a mammal an effective amount of at least one immunogen selected from the group consisting of: (i) a peptide based on a CDR of the heavy or light chain of an anti-p53 mAb, which peptide is capable of eliciting antibodies to p53; and (ii) a DNA molecule coding for the variable (V) region of an anti-p53 mAb in a suitable gene delivery vehicle. Preferably the immunogen is administered in the form of a pharmaceutical composition. Preferably the peptide is 7 to 30 amino acid residues in length and contains a sequence of the CDR2 or CDR3 of the heavy chain, or of the CDR3 of the light chain of an anti-p53 mAb.
