Jonas Edward Salk (; born Jonas Salk; October 28, 1914 – June 23, 1995) was an American virologist and medical researcher who developed one of the first successful polio vaccines. He was born in New York City and attended the City College of New York and New York University School of Medicine.[2]
In 1947, Salk accepted a professorship at the University of Pittsburgh School of Medicine, where he undertook a project beginning in 1948 to determine the number of different types of poliovirus. For the next seven years, Salk devoted himself to developing a vaccine against polio.
Salk was immediately hailed as a "miracle worker" when the vaccine's success was first made public in April 1955, and chose to not patent the vaccine or seek any profit from it in order to maximize its global distribution.[2] The National Foundation for Infantile Paralysis and the University of Pittsburgh looked into patenting the vaccine, but since Salk's techniques were not novel, their patent attorney said, "If there were any patentable novelty to be found in this phase it would lie within an extremely narrow scope and would be of do

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.
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 chi
