Research and development of unconventional systems for immunization.
The problems raised by the ever expanding world population justify the work of USAID (U.S. Agency for International Development). Continual efforts must be made to develop and efficiently operate methods of control of the microbial and parasitic infections which menace our sources of protein. This programme includes immunization, technical methods in bacterial and viral genetics to obtain attenuated strains, and improvements in production, preservation and distribution of preparations. An example of  an unconventional but promising system of application is the pilot study recently begun in the Missouri-Mississippi River region.
