High-Dose Flu Vaccine Linked to Lower Alzheimer's Risk in Older Adults
A recent study published in Neurology has found that receiving a high-dose flu vaccine is associated with a significantly lower risk of developing Alzheimer's disease in adults aged 65 and older. Conducted by researchers at the McGovern Medical School at UTHealth in Houston, the study analyzed health data from approximately 165,000 older adults who received either a high-dose or standard-dose influenza vaccine. The findings revealed that the high-dose flu vaccine reduced the risk of Alzheimer's by nearly 55% over a two-year period. This study builds on previous research by the same team, which found that the standard-dose vaccine was linked to a 40% reduced risk of Alzheimer's over four years. The high-dose vaccine contains four times the antigen of standard-dose vaccines, which is believed to enhance immune response and reduce inflammation, a factor thought to contribute to Alzheimer's development.
