The first mass inoculation of children against polio with the Salk vaccine begins in Pittsburgh. Salk campaigned for mandatory vaccination, claiming that public health should be considered a “moral commitment.” His sole focus had been to develop a safe and effective vaccine as rapidly as possible, with no interest in personal profit. When asked who owned the patent to it, Salk said, “There is no patent. Could you patent the sun?” Until the Salk vaccine was introduced, polio was considered one of the most frightening public health problems in the world. The 1952 U.S. epidemic was the worst outbreak in the nation’s history. Of nearly 58,000 cases reported that year, 3,145 people died and 21,269 were left with mild to disabling paralysis, with most of its victims being children.
