Population is growing at a rapid pace in many economically developing countries and there is a continuing need of an alternate method for regulation of fertility. We proposed several years back a birth control vaccine which induces the formation of antibodies against the human pregnancy hormone, the human chorionic gonadotropin (hCG). These inventions are described in patents issued in India, U.S.A. and several other countries. (Ref. EP 204566, JP 62286928, CA 1239346, U.S. Pat. No. 4,780,312, CN 8603854). We describe now another invention which generates antibody response of a long duration against hCG after a single or a limited number of injections.
