Contributions to the Field

Jonas Salk was best known for his development of the first polio vaccine. 1943 he developed a formalin-killed-virus vaccine against A and B influenza and were ready to start clinical trials. 1946 he expanded his research from the way that the human body reacts to viruses to their epidemic effect on populations. 1951 Jonas Salk narrowed the polio virus into one of three types from being extremely infectios to barely so and with this information he could then go on to develop his vaccine.

Development of the Vaccine

Development of the Vaccine

He believed that they schould use a killed polio virus as oppsed to a live one to avoid accidently infecting the patient with the virus. He exposed the virus to formaldehyde for 13 days. Eventhough after three days he couldn't detect the virus in the sample, he continued to expose it for 10 more days to assure that it was dead. He then tested it on monkeys
