Flu Vaccine May Slash Alzheimer's Risk
A new study published in Neurology suggests that influenza vaccination, particularly the high-dose formulation given to adults 65 and older, may be associated with a reduced risk of Alzheimer’s disease.
Analysis of health records from approximately 200,000 older adults found a 55% lower Alzheimer’s risk among high-dose vaccine recipients compared with about 40% among standard-dose recipients. Researchers also observed a stronger protective association in women.

While the findings add to emerging evidence linking routine vaccinations with potential cognitive benefits, experts caution that causality is not established and emphasize the need for longer-term and randomized studies to confirm mechanisms and outcomes. Read more from Medical News Today here.
