Longevity & AgingThe Shingles Vaccine May Protect Your Heart and Brain Too
The shingles vaccine, best known for preventing painful nerve infections, is showing surprising cardiovascular and cognitive benefits. Multiple large studies — including a Stanford Medicine analysis and a major Korean cardiovascular cohort — suggest that vaccinated individuals have significantly lower rates of stroke, heart attack, and dementia. A natural experiment in Wales confirmed a causal reduction in dementia risk. The likely mechanism involves the herpes zoster virus triggering chronic vascular inflammation, which the vaccine may prevent. For health-conscious adults over 50, this adds compelling new reasons to get vaccinated beyond shingles prevention alone. Dr. Brad Stanfield reviews the growing body of peer-reviewed evidence, drawing on sources from Nature, the European Heart Journal, and ACC 2026 conference data.
