Well like many medical breakthroughs, there were a succession of findings by many scientists which led to an ultimate polio vaccine.

But it was a scientist by the name of Dr Jonas Salk who, with the help of his colleagues at University of Pittsburgh Medical School, discovered the polio vaccine itself.
Polio Vaccine In 1947, Salk took a position at University of Pittsburgh, where he began conducting research on polio, also known as infantile paralysis. By 1951, Salk had determined that there were three distinct types of polio viruses and was able to develop a killed virus vaccine for the disease. The vaccine used polio viruses that had been grown in a laboratory and then destroyed. Preliminary testing of the polio vaccine began in 1952 - the shot given mostly to children. National testing expanded over the next two years, making it one of the largest clinical trials in medical history. Roughly 1.8 million children were given the vaccine during the test phase.
