Shingles vaccine linked to 24% lower dementia risk
Researchers found the association in more than 500,000 older adults, but they said randomized clinical trials are needed to confirm whether it is causal.
- A study published in the Annals of Internal Medicine on Wednesday found that older adults receiving the recombinant zoster vaccine showed a 24% lower risk of dementia over four years.
- Researchers from Brown University analyzed Medicare claims and electronic health records for over 500,000 older adults admitted to skilled nursing facilities between 2017 and 2022.
- Over a four-year follow-up, dementia developed in 18.8% of vaccinated participants versus 24.6% of those who remained unvaccinated, translating to roughly one dementia case prevented for every 17 people vaccinated.
- Lead author Kaley Hayes noted the findings could support both physical and cognitive health, though researchers emphasize clinical trials are required to confirm if the vaccine directly lowers dementia risk.
- This potential preventive measure may point to broader cognitive benefits for high-risk nursing-home populations, pending further investigation into the vaccine's specific mechanisms of action.
