Researchers here note a sizable reduction in Alzheimer’s disease risk in that part of the aged population that receives influenza vaccines. There is the usual question as to whether vaccination is a proxy for conscientiousness in health matters throughout later life, but here the focus is on biological mechanisms that might explain the effect. The most plausible to my eyes is the phenomenon of trained immunity, in which vaccination for a specific pathogen can provoke a general improvement in all functions of the innate immune system. This improvement includes reduced inflammation, and the <a href="https://www.fightaging…
