Question: the man who created the polio vaccine?
Answer: Jonas Salk (1914–1995) became a national hero when he allayed the fear of the dreaded disease with his polio vaccine, approved in 1955. Although it was the first polio vaccine, it was not to be the last; Albert Bruce Sabin (1906–1993) introduced an oral vaccine in the United States in the 1960s that replaced Salk's.
