Albert Sabin a vaccine to prevent or mitigate the illness. The Sabin vaccine is an oral vaccine containing weakened forms of strains of polio viruses. In 1955, Salk's "killed" vaccine was released for use. It 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 in 1954, and its effects last longer. Sabin first tested his live attenuated oral vaccine at the Chillicothe Ohio Reformatory in late 1954. From 1956–1960, he worked with Russian colleagues to perfect the oral vaccine
Albert Kapikian Albert Kapikian Albert Zaven Kapikian (1930 – 2014) was an Armenian-American virologist who developed the first licensed vaccine against rotavirus, the most common cause of severe diarrhea in infants. He was awarded the Sabin Gold Medal for his pioneering work on the vaccine. He is the 13th recipient of this recognition, awarded annually by the Sabin Vaccine Institute. Called the father of human gastroenteritis virus research, Kapikian identified the first norovirus, initially called Norwalk virus, in 1972; and he and his colleagues at the National Institutes of Health identified the hepatitis A virus in 1973. Kapikian graduated from Cornell Medical
