Flu and pneumonia shots may lower risk for Alzheimer’s, studies find

CNN (07/27/2020)
  • 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%.
