Baltimore—As a young student, Walter Orenstein, MD, head of the US National Immunization Program, idolized Jonas Salk, MD. Orenstein's favorite story about the discoverer of one polio vaccine takes place at a meeting where the well-known friction between Salk (who died in 1995) and the other polio vaccine discoverer, Albert Sabin, MD (who died in 1993), came to a head. As participants debated the merits of the Salk and Sabin vaccines, Salk stood up and said, "There is something we can agree on. The world needs just one vaccine."
