Shingles Vaccine May Prevent Dementia: Evidence Continues to Strengthen
A growing body of research suggests that the shingles vaccine does more than prevent a painful rash — it may significantly reduce the risk of dementia, including Alzheimer's disease, and even slow biological aging. The latest studies add to evidence that has been accumulating for years.
Key Takeaways
- Multiple studies link shingles vaccination to significantly lower dementia risk
- Latest research shows the vaccine may slow biological aging and reduce inflammation
- Leading theory: vaccine prevents subclinical viral reactivation that damages neural tissue
- Randomized controlled trials needed to confirm causation, but evidence is growing
- If confirmed, an existing vaccine could become a major dementia prevention tool
