As demonstrated by Leonard Hayflick a half-century ago, human cells have a limited replicative lifespan, with older cells reaching this limit sooner than younger cells.
Not long ago, the microbiologist Leonard Hayflick was asked what had changed since he began his career 55 years ago.
"Vaccination is a particularly important issue to think about now, given the rise of an anti-vaccine movement that has the potential to reverse the health gains achieved through one of the most powerful interventions in medical history," co-author Leonard Hayflick, from the University of California, San Francisco, said in (https://news.uic.edu/ten-million-lives-saved-by-1962-breakthrough-study-says) a statement from the University of Illinois at Chicago, both institutions that worked on the project.
Biologists Leonard Hayflick and Colin Blakemore appearas skeptical counterpoints.
The Hayflick limit, named after Leonard Hayflick, is the limit on the number of times a given cell can divide.

Leonard Hayflick. Audrey was a Research Fellow and Professor of Biology and Biotechnology at Worcester Polytechnic Institute in Worcester, MA from 1976 to 1983.
This phenomenon is known as the Hayflick limit, after Leonard Hayflick, who with Paul Moorhead described it in 1961 while at the Wistar Institute in Philadelphia.
Por la misma epoca, Alexsei Matveevich Olovnikov, un desconocido cientifico ruso, hallo el eslabon entre el problema de la replicacion terminal -enunciado por Watson-y la senescencia celular, a su vez previamente descrita por Leonard Hayflick. Segun Hayflick y Moorhead (4), la senescencia correspondia a un estado de detencion de la proliferacion, al que ingresaban las celulas somaticas humanas con signos de alteraciones bioquimicas y morfologicas como producto de haber sobrepasado su capacidad limite de division.
