Answer:

Jonas Salk became a national hero when he allayed the fear of polio with his vaccine, approved in 1955. Although it was the first polio vaccine, it was not to be the last; Albert Sabin introduced an oral vaccine in the 1960s that replaced Salk’s.

Polio Season

In the first half of the 20th century, summer was a dreaded time for children. Although they could enjoy the long days of unfettered play, summer was also known as “polio season.” Children were among the most susceptible to paralytic poliomyelitis (also known as infantile paralysis), a disease that affects the central nervous system and can result in paralysis. When exposed to a poliovirus in the first months of life, infants usually manifested only mild symptoms because they were protected from paralysis by maternal antibodies still present in their bodies. However, as hygienic conditions improved and fewer newborns were exposed to the virus (which is present in human sewage), paralytic poliomyelitis began to appear in older children and adults who did not have an infant’s benefit of immunity. President Franklin Delano Roosevelt is perhaps the most famous victim of the poliovirus. In 1921, at the age of 39, he contracted the disease, one of the thousands that were afflicted that year.

The Vaccines

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.
