## Hilary KoprowskiBorn 5 Dec 1916; died 11 Apr 2013 at age 96.Polish virologist and immunologist who discovered the first vaccine against poliomyelitis which was based on oral administration of attenuated polio virus. In researching a polio vaccine, he decided to focus on the use of live viruses that were attenuated (rendered non-virulent) instead of the killed viruses that became the basis for the injections created by Jonas Salk. Koprowski viewed the live vaccine as more powerful since it entered the intestinal tract directly and could provide lifelong immunity, whereas the Salk vaccine required boosters. Also, taking a vaccine by mouth is easy, whereas an injection is more expensive and needs medical facilities. It was taken by the first child on 27 Feb 1950 and within 10 years was used for immunization on four continents. |
