Dr Hilary Koprowski, the Polish-American researcher who developed the first successful oral vaccine for polio, has passed away. He was 96.
Unlike HIS more well-known co-researchers Jonas Salk and Albert Sabin, Koprowski’s 1950 clinical trial was the first one to prove that it was possible to have an anti- polio vaccine for the crippling disease. Hilary Koprowski consumed the live-virus oral vaccine before the 1950 trial — about two years before Salk’s injectable version using a dead form of the virus began testing. He also led the team which developed a rubella vaccine that helped eradicate the disease.
