Shingles Vaccine Associated with Reduced Risk of Dementia, Major Nature Study Finds

A large-scale study published in Nature Communications has found that the recombinant zoster (shingles) vaccine is associated with a significantly reduced risk of developing dementia. The findings add to growing evidence that viral infections and the immune system play a role in neurodegenerative diseases, and suggest that a widely available vaccine could have unexpected benefits for brain health in aging populations.
