Can getting a flu or pneumonia vaccination prevent Alzheimer’s Disease?
A study performed in 2020 shows that receiving a flu vaccination is associated with a 17% reduction in Alzheimer’s Disease. More frequent flu vaccinations reduce the risk by another 13%.
The study also found that receiving a pneumonia vaccination reduced the risk of Alzheimer’s Disease by up to 40%.
The reason for the reduction is not clear. One researcher stated that it may simply be that individuals who take care of their own health by getting immunized also take care of themselves better in other ways, such as eating healthier and getting more exercise, which are also known to reduce the risk of Alzheimer’s.
The 2020 study is remarkable in that it showed a marked reduction in Alzheimer’s in those individuals who were immunized. More studies are needed to find out the exact mechanism of how the vaccinations reduced the risk of Alzheimer’s Disease.
