Shingrix vaccination associated with reduced dementia risk in older adults

A study of over 500,000 Medicare beneficiaries aged 66 and older found that those who received the Shingrix shingles vaccine had a 24% lower risk of dementia diagnosis over four years. The analysis, led by Kaley Hayes of Brown University, focused on adults entering skilled nursing facilities and compared vaccinated with unvaccinated individuals. The results add to evidence that shingles vaccination may have neuroprotective benefits.
