Jonas Salk

Medical researcher who developed the first successful polio vaccine, saving millions of lives.

Dr. Jonas Salk (1914–1995) transformed global health by creating the first effective polio vaccine in 1955, a breakthrough that eradicated one of the 20th century’s most feared diseases. Unlike contemporaries, Salk rejected patenting his vaccine, stating, 'Could you patent the sun?'

Polio paralyzed over 15,000 Americans annually before Salk’s vaccine. His innovative use of inactivated virus technology ensured safety and efficacy, validated by a 1954 trial involving 1.8 million children. By 1961, U.S. cases dropped by 96%. The World Health Organization later used his model to nearly eliminate polio worldwide.

Salk’s approach prioritized collaboration over profit. He founded the Salk Institute in 1963 to blend science and humanism, attracting Nobel laureates like Francis Crick. His work inspired future vaccines, including COVID-19 mRNA technologies.

Beyond polio, Salk researched AIDS and advocated for equitable healthcare. His legacy exemplifies how altruistic science can reshape society.
