"In 1982 Barry visited Taiwan, where the director of the blood bank at a major hospital in Taipei showed him large refrigerators full of blood from people infected with hepatitis B. What should they do with all these contaminated bottles of blood, the director asked? Barry’s answer: they should make hepatitis B vaccine. The Taiwanese hospital adopted his recommendation, which led by 1984 to Taiwan establishing the world’s first program of universal hepatitis B vaccination."
