Worldwide production of vaccines using the WI-38 cell strain
Leonard Hayflick Scientist

The proceedings were subsequently published in book form and it contained an array of papers, including many from the laboratory of Drago Ikić in which he described the preparation of vaccines against several virus diseases; not only polio. So, it sets the stage now for worldwide production of vaccines on WI-38 and eventually other cell populations.

The other important cell populations I may have mentioned earlier, but I'll now link it to these events was MRC-5. That strain was developed by Frank Perkins seven years after I published on WI-38, and it is identical to WI-38 in all respects other than it, of course, came from a different embryo. Several countries, but Frank was first, wanted their own strain for purposes of national pride, which was... is understandable, of course. They're very easy to make, following my recipe. And MRC-5 was used in later years for polio vaccine production and other vaccines, and it's used even to this day along with WI-38. MRC stands, of course, for... for Medical Research Council in Hampstead. There... and Frank laid down, of course, many hundreds of ampoules for this subsequent distribution.

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.
