WASHINGTON (AP) - The Polish-born medical pioneer Albert Sabin, who developed the oral vaccine that helped to end the threat of polio, died yesterday of congestive heart failure at Georgetown University Medical Center in Washington. He was 86. He was admitted to the hospital on 22 February. The oral vaccine that Sabin developed, together with an injectable type found earlier by Jonas Salk, helped to eliminate the paralysing disease. Sabin tested his vaccine on himself and prison volunteers before it gained wide acceptance. He was born in 1906 in Bialystok, Poland and came to the US in 1920.
