A brief history and inventory of immunizations

Abstract

This article attempts to summarize succinctly the origins, past history, present armamentarium, and possible future directions of immunizing agents. Individual discoveries and governmental initiatives have led to large-scale immunization programs that have proven the success of this primary preventive tool. Examples of missed opportunities have been noted. Like previous vaccines, the newer vaccines will require scientific proof of efficacy and public acceptance. Unlike other primary preventive tools (chlorination of water, pasteurization of milk), future successful immunization programs will require active participation, of the public and continuous governmental education in order to protect its citizens.
