Shingles Vaccine Linked to Slower Biological Aging in Older Adults
A recent observational study of nearly 4,000 adults aged 70+ found that shingles vaccination was linked to slower overall biological aging and lower inflammation, suggesting immune-related benefits beyond preventing shingles. However, the study cannot establish causality, and more research—including randomized trials and diverse populations—is needed to confirm these findings and explore health outcomes such as cognitive decline or mortality.
