Polio vaccine [SEP] Introduction
This compares with 5,000 cases per million who are paralysed following a polio infection. Both are generally safe to give during pregnancy and in those who have HIV/AIDS but are otherwise well. The first successful demonstration of a polio vaccine was by Hilary Koprowski in 1950, with a live attenuated virus which people drank. The vaccine was not approved for use in the United States, but was used successfully elsewhere. An inactivated polio vaccine, developed a few years later by Jonas Salk, came into use in 1955. A different, oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961.
