The American microbiologist Albert Bruce Sabin (b.1906). In the 40s other microbiologists such as the American Enders had developed new techniques to produce cultures of polio virus in quantities adequate for experimentation. This enabled Sabin in 1957 to improve the first vaccine for poliomyelitis obtained in 1953 by another American microbiologist, Jonas Salk. Sabin, working with the living virus, was able to obtain a vaccine which had a longer-lasting immunity and the capability of being given orally.
