Vaccines May Lower Dementia Risk: New Data on Flu, Shingles, and Heart Health
Recent research indicates that routine vaccinations, particularly for flu and shingles, may significantly reduce the risk of developing dementia and cardiovascular diseases. A 2022 study found that older adults receiving the flu vaccine had a 40% lower risk of Alzheimer's, while a 2025 meta-analysis suggested that multiple doses could reduce dementia risk by up to 57% in high-risk groups. Shingles vaccination has also been linked to a 20% reduction in dementia risk, with some studies showing additional benefits for heart health. While these findings are observational and do not prove causation, experts suggest that vaccines may protect the brain by reducing inflammation and preventing infections that contribute to cognitive decline.
