The polio vaccine developed by Dr. Salk and colleagues is licensed in the U.S. Before the polio vaccine, the disease had been a major cause of disability in children. About 16,000 cases of polio (paralytic poliomyelitis) occurred each year in the U.S. in the 20th century compared with none in 2020.

18 wrz 2024 · Jonas Salk (October 28, 1914 - June 23, 1995) was an American medical researcher celebrated for his pioneering work in virology, particularly the development of the first successful polio vaccine. This review highlights Salk's multifaceted talent and contributions.
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.
Contrary to the era’s prevailing scientific opinion, Salk believed his vaccine, composed of “killed” polio virus, could immunize without risk of infecting the patient. Salk administered the vaccine to volunteers who had not had polio, including himself, his lab scientist, his wife and their children.
