As polio epidemics hit US cities, President Roosevelt helps create the private National Foundation for Infantile Paralysis. The Foundation's drive to help find a vaccine becomes the highly publicized 'March of Dimes' campaign, largely funded by individual contributions by Americans. These donations would also pay for a large part of the country's immunization campaigns after the introduction of polio vaccines in the mid-1950s.
