Albert Bruce Sabin (b.1906), US microbiologist. In the 1940s 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 to improve the first vaccine for poliomyelitis, obtained in 1953 by another American microbiologist, Jonas Salk. Sabin, working with the living virus in 1957, was able to obtain a vaccine which had a longer-lasting immunity and the capability of being given orally.
