Salk Polio Vaccine
Pioneering research here at the University of Pittsburgh's Virus Research Laboratory from 1948 to 1955 produced the world's first polio vaccine. Led by Dr. Jonas Salk, researchers' innovations resulted in a breakthrough that was announced on April 12, 1955. Subsequent inoculations of school children virtually eradicated polio in the United States by 1962.
