Stronger Flu Vaccine May Shield Seniors From Alzheimer's, Large Study Finds
A UTHealth Houston study of nearly 200,000 adults aged 65+ found that recipients of the high-dose influenza vaccine had about a 55% lower risk of developing Alzheimer’s disease compared with those who received the standard dose, with stronger effects in women. The finding builds on earlier work showing roughly a 40% risk reduction from influenza vaccination and suggests vaccine dosage may influence brain health, though access to high-dose vaccines remains uneven.
