He became a professor at University of Pittsburgh, where he worked with Jonas Salk on a vaccine for polio. While at Pittsburgh, he also isolated ECHO 16, the virus responsible for Boston exanthem disease. This was the first description of that disease. Together with Thomas Weller, he isolated the Rubella virus in 1962. In 1964 he moved back to Harvard to head the Department of Tropical Public Health. In 1969 he joined the National Institutes

And so, by carefully designed experiments, we found it was possible to do so."
