Hilary Kaprowski was a pioneer in polio vaccines. In fact, that's not widely known for reasons that I'm unaware of, but he was the first actually to produce and test a live virus vaccine, contrary to the popular belief that it was Albert Sabin, it was not Albert Sabin, it was Hilary Kaprowski.

Leonard Hayflick (b. 1928), the recipient of several research prizes and awards, including the 1991 Sandoz Prize for Gerontological Research, is known for his research in cell biology, virus vaccine development, and mycoplasmology. He also has studied the ageing process for more than thirty years. Hayflick is known for discovering that human cells divide for a limited number of times in vitro (refuting the contention by Alexis Carrel that normal body cells are immortal), which is known as the Hayflick limit, as well as developing the first normal human diploid cell strains for studies on human ageing and for research use throughout the world. He also made the first oral polio vaccine produced in a continuously propogated cell strain - work which contributed to significant virus vaccine development.
