Pueblo Q: Some individuals are avoiding getting the flu shots claiming the vaccine causes early onset of Alzheimers disease. Is there and what is the basis of this concern?
I (JJC) can find no scientific data that even hints at a connection between the two. But that doesn’t mean there aren’t dozens of Web sites that claim a connection. Most are what I would call “quack” sites, and come from conspiracy theorists. In many cases people are making what’s called the “post-hoc fallacy;” if one thing happens after another, it must be that the first thing caused it. Mother gets a flu shot and two years later is diagnosed with Alzheimer’s; the shots must have caused it.
