Salk vaccine
Quick Summary
The Salk vaccine, developed by American physician Jonas Salk, is a polio vaccine that uses inactivated poliovirus to prevent the disease. Polio is a viral infectious disease that can cause paralysis, though most infected individuals show no symptoms. In the mid-20th century, hundreds of thousands of children were affected annually by polio.123
Salk's vaccine, tested in 1952 and released in 1955, was administered by injection and significantly reduced polio incidence. A second vaccine, the Sabin vaccine, which uses live attenuated virus and is given orally, was developed later. Widespread vaccination has led to the elimination of polio from most of the world, with only Afghanistan and Pakistan remaining endemic as of 2022.1453
