ALBERT B. SABIN (1906-1993). Polish American medical researcher Albert B. Sabin developed the oral polio vaccine. The Sabin vaccine is an oral vaccine containing weakened forms of strains of polio viruses. Salk's vaccine was effective in preventing most of the complications of polio, but did not prevent the initial intestinal infection.

The Sabin vaccine is easier to give than the earlier vaccine developed by Salk and its effects last longer. It worked in the intestines to block the poliovirus from entering the bloodstream. In the intestines, Sabin had discovered, the poliovirus multiplied and attacked. Thus, the oral vaccine broke the chain of transmission of the virus and allowed for the possibility that polio might one day be eradicated. From 1969-1972, Sabin served as the President of the Weizmann Institute of Science in Israel.
