Flu (influenza) and pneumonia vaccinations are associated with reduced risk of Alzheimer’s disease, according to new research reported at the Alzheimer’s Association International Conference® (AAIC®) 2020.

Three research studies reported at AAIC 2020 suggest:

• At least one flu vaccination was associated with a 17% reduction in Alzheimer's incidence. More frequent flu vaccination was associated with another 13% reduction in Alzheimer's incidence.
• Vaccination against pneumonia between ages 65 and 75 reduced Alzheimer's risk by up to 40% depending on individual genes.
• Individuals with dementia have a higher risk of dying (6-fold) after infections than those without dementia (3-fold).
