People who get yearly flu vaccines probably go to the doctor more regularly than those who do not. I would expect that people who more regularly go to the doctor are also more concerned about their health. I'd expect people who are concerned with their health to behave in ways that limit disease.

Without a proposed method of action, I suspect this is just noise.

There’s a section in https://content.iospress.com/articles/journal-of-alzheimers-... called Hypothesized Mechanism(s), which contains (amongst supporting details) the following:

> 1) influenza-specific mechanisms, including mitigation of damage secondary to influenza infection and/or epitopic similarity between influenza proteins and AD pathology; 2) non–influenza-specific training of the innate immune system; and 3) non–influenza-specific changes in adaptive immunity via lymphocyte-mediated cross-reactivity.
