High-Dose Flu Vaccines: Reducing Alzheimer's Risk

Created using ChatSlide

This presentation examines whether high-dose influenza vaccination is associated with reduced Alzheimer’s disease risk among adults aged 65 and older. Using IQVIA PharMetrics data from 2014–2019, it compares standard and high-dose vaccines in individuals without prior cognitive impairment over a three-year follow-up. Key findings suggest lower AD risk with high-dose vaccination, especially among women, while noting study limitations and the need for further research.
