The big discovery was made by Leonard Hayflick of the University of California, San Francisco, and swiftly applied through worldwide vaccination programs. Hayflick, one of the study's coauthors, in a press release. Co-author S. Jay Olshansky, an epidemiologist and biostatistician at the University of Illinois at Chicago School of Public Health, was able to estimate the number of disease cases prevented and lives saved by Hayflick's breakthrough by looking back at prevalence rate data published for the diseases in 1960 (before the introduction of WI-38). Because the vaccines for the diseases came out at different times, Olshansky multiplied the number of years between each vaccine's debut and 2015 by the number of reported cases and deaths in 1960, and calculated the impact of each vaccine from there. But one question remains: Why are some parents playing so fast and loose with their kids' and their community's health and well-being when we have these effective, life saving vaccines? Perhaps, Olshansky suggests, it's because we've forgotten past horrors and may be dooming ourselves to repeat them. Worldwide, an estimated 1.4 million children under the age of 5 still die each year due to lack of access to vaccines.
