Abstract

The present invention is directed to a method of protecting an animal against a chronic disease, the disease being caused by an infectious organism which undergoes more than one stage in its life cycle or undergoes more than one infectious cycle. The method comprises: a) administering to the animal a live vaccine containing sufficient organisms to develop an immunological response in the animal; b) maintaining the animal free from chemotherapeutic agents effective against the infectious organism for a period of time corresponding to about one life or infectious cycle of the organism; and c) thereafter administering to the animal a chemotherapeutic agent effective against the infectious organism for a period of time corresponding to at least one life or infectious cycle of the infectious organism.

       2 . A method as claimed in  claim 1  wherein the animal is maintained free from chemotherapeutic agents effective against the infectious organism for a period of time corresponding to about two to five days beyond one life cycle or infectious cycle of the organism.
