| The first effective vaccine used as a preventative against poliomyelitis was developed in 1952 by Jonas Salk. Salk’s earlier work on an anti-influenza vaccine during the 1940s led to his discovery. By the mid-1950s, the vaccine had been widely distributed in the United States, greatly reducing the domestic incidence of polio. | ||||||
