The Polio Vaccine

The discovery of the polio vaccine was an important medical and scientific breakthrough because it saved many lives since the 1950s. In the summer of 1916 the great polio epidemic struck the United states. By the 1950s hundreds of thousands of people had been struck by the poliomyelitis. The highest number of cases occurred in 1953 with over 50,000 people infected with the virus. When hygienic conditions were poor polio attacked infants.

One was to continue the work he was doing on influenza, second was to begin working with the polio virus. A few months after arriving in Pittsburgh, Salk was visited by the director of research at the National Foundation for Infantile Paralysis.

Salk's previous work gave him the idea that a killed virus could in fact work when others thought it couldn't. To type the polio virus Salk infected monkeys with polio by injecting it into them or feeding it to them. If a monkey survived it built up antibodies to protect against the virus. The monkeys that survived were then given another type of virus to see if the same antibodies protected against the second type. If it did, it told Salk and his assistants that the two types were related. If it did not, that told Salk that they were not related. Eventually
