Shingles Shot May Slow the Body's Aging Clock, USC Study Finds
A USC Leonard Davis School of Gerontology study analyzing the Health and Retirement Study (about 3,800 people aged 70+ in 2016) found that those who received the shingles vaccine had slower biological aging on several measures—lower inflammation and slower epigenetic and transcriptomic aging—than unvaccinated peers, suggesting vaccines may influence aging beyond preventing shingles, with effects lasting at least four years after vaccination; the results show an association, not causation.
