Option D

Correct Option

Option C

Explanation

In the early 1950s, 25,000 to 50,000 new cases of polio occurred each year. 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. Although the disease was finally brought under control because of these vaccines, the science behind them fired debate that continues to this day.
