- A University of Texas study covering 9,000 patients over 60 found a 17% reduction in Alzheimer’s incidence associated with having just one flu vaccination.
- Those who were vaccinated more than once had a further 13% incidence reduction.
- While the biological reason for this decline remains unknown, one theory is that vaccination helps keep the immune system “in shape” as people age.
- Another study found that getting the pneumococcal vaccine between the ages of 65-75 reduced Alzheimer’s risk by 25-30%.
