The announcement on 12 April 1955 that Dr. Jonas Salk’s polio vaccine was safe, effective, and potent showed that polio eradication was a possibility and cemented Salk’s legacy. His son, Dr. Peter Salk, is the president and director of the Jonas Salk Legacy Foundation as well as a professor of infectious diseases and microbiology at the University of Pittsburgh School of Public Health. Rotary magazine recently spoke with him to discuss immunizations and polio eradication.
