Detailed explanation-1: -Salk tested his experimental killed-virus vaccine on himself and his family in 1953, and a year later on 1.6 million children in Canada, Finland and the USA. The results were announced on 12 April 1955, and Salk’s inactivated polio vaccine (IPV) was licensed on the same day.
Detailed explanation-2: -On March 26, 1953, American medical researcher Dr. Jonas Salk announces on a national radio show that he has successfully tested a vaccine against poliomyelitis, the virus that causes the crippling disease of polio.
Detailed explanation-3: -For the next seven years, Salk devoted himself towards 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.
