Aging and infectious diseases picked up years or decades ago are far more related than previously thought.

First was the Epstein-Barr virus and MS (multiple sclerosis):
"Longitudinal analysis reveals high prevalence of Epstein-Barr virus associated with multiple sclerosis", Bjornevik et al. 2022

Now the shingles vaccine and its effect on dementia:
"The effect of shingles vaccination at different stages of the dementia disease course", Xie et al. 2025

One wonders what else, and why aren't we vaccinating against many more illnesses, in this age of potentially rapid development of mRNA vaccines.
