The Impact of Jonas Salk's Polio Vaccine: A Turning Point in Medical History

The video discusses the development and impact of the polio vaccine by Dr. Jonas Salk and his team at the University of Pittsburgh. It highlights the severe impact of polio in the US during the late 1800s, particularly on children, and shares a personal story of Jerry Carroll, a polio survivor. The approval of the vaccine led to a significant decline in polio cases in the US from 1955 to 1961. Although polio was eradicated in the Americas by 1994, it still persists in parts of Asia and Africa. The last US case of polio from the wild virus was in 1979.
