Shingles vaccine may reduce dementia risk by 20% in older adults, study suggests.

A new study in Nature suggests that the shingles vaccine may cut the risk of dementia by 20% in older adults over seven years. Researchers analyzed over 280,000 medical records from Wales, finding that those vaccinated against shingles were less likely to develop dementia than those who were not vaccinated. The study focused on the older vaccine version, and further research is needed to confirm if the newer vaccine, Shingrix, offers similar protection. The findings add to the understanding of how vaccines might benefit brain health.
