Hereby, we disclose and claim, the concept, designs, enabling technologies, and utility for therapy of patients suffering from cancer, of a novel class of biomolecularly engineered, synthetic molecules: antibody-vaccine engineered constructs (AVEC). They comprise the main functional domains (antibodies and vaccines) and the supporting domains (linkers and reporters). Their mechanisms of actions rely upon antibody dependent redirecting, accelerating, and amplifying of the prophylactic or natural vaccination induced immune response (ADRAAVIR) from the initially elicited by vaccination towards the finally aimed by therapies. The routes of administration to the patients, pharmacokinetics, pharmacodynamics, pharmacogenomics, and therapeutic efficacies are resultant of those of the pertinent antibodies and vaccines assembled within AVEC.
