The first mass distribution in the United States of Dr. Albert Sabin's oral polio vaccine begins, with thousands of schoolchildren in Cincinnati the first recipients. (The year before, millions of children in the Soviet Union had been given the vaccine.) It was often given in the form of a sugar cube laced with the vaccine. Sabin's method of oral immunization came 5 years later after Dr. Jonas Salk's polio vaccine, which was administered by inoculation.
