The invention relates to methods and compositions for causing the selective targeting and killing of tumor cells. The present invention describes prophylactic or therapeutic cancer vaccines based on purified TAA proteins or TAA-derived synthetic peptides altered by chemical, enzymatic or chemo-enzymatic methods to introduce αGal epitopes or αGal glycomimetic epitopes, in order to allow for enhanced opsonization of the antigen by natural anti-αGal antibodies to stimulate TAA capture and presentation, thereby inducing a humoral and cellular immune response to the TAA expressed by a tumor. The animal's immune system thus is stimulated to produce tumor specific cytotoxic cells and antibodies which will attack and kill tumor cells present in the animal.
