Scientists Find Shingles Vaccine Lowers Dementia Risk and Impacts Inflammation

Recent research indicates that the shingles vaccine may offer benefits beyond preventing shingles, including a potential reduction in dementia risk. An analysis of over 100 million U.S. patients found that recipients of the shingles vaccine had up to a 33% lower risk of developing dementia compared with those receiving other recommended vaccines.

Experts suggest the vaccine may reduce brain inflammation linked to dementia by preventing reactivation of the varicella zoster virus. While further clinical trials are needed, these findings reinforce public health guidance encouraging vaccination for older adults, highlighting its broader implications for long-term health.
