As a fellow at Children's Hospital Boston, Thomas C. Peebles worked with John Franklin Enders. Enders became known as "The Father of Modern vaccines", and Enders shared the Nobel Prize in 1954 for his research on cultivating the polio virus that led to the development of a vaccination for the disease. Switching to study measles, Enders sent Peebles to Fay School in Massachusetts, where an outbreak of the disease was under way, and there Peebles was able to isolate the virus from some of the blood samples and throat swabs he had taken from the students. Even after Enders had taken him off the study team, Peebles was able to cultivate the virus and show that the disease could be passed on to monkeys inoculated with the material he had collected. Enders was able to use the cultivated virus to develop a measles vaccine in 1963 based on the material isolated by Peebles. In the late 1950s and early 1960s, nearly twice as many children died from measles as from polio. The vaccine Enders developed was based on the Edmonston strain of attenuated live measles virus, which was named for the Fay student from whom Peebles had taken the culture that led to the virus's cultivation.
