We've seen the Shingles vaccine is linked with reduced risk of Alzheimer's and dementias in 4 large natural experiments.
Today, the potential of high-dose flu vaccines vs standard dose for the same in a large retrospective age 65+ cohort [N>160,000). More pronounced in women (like Shingles vaccine)

With the rise of new tools in molecular biology, it’s becoming clear that viruses and other pathogens can remain in the body or otherwise affect its workings for a surprisingly long time https://t.co/d3VNRILaTA
Multiple lines of evidence are converging on the idea that viruses you picked up decades ago might quietly be driving age-related diseases.
We've known for a few years that EBV raises MS risk 32-fold, and that molecular mimicry between an EBV protein and nerve insulation likely triggers brain autoimmunity. What remained unclear was why some people persistently carry EBV and others don't.
A new paper in @Nature from the @RyanDhindsa (whose lab has been supported by @impetusgrants) and @CalebLareau labs answers that at population scale. They mined ~735,000 human genomes for traces of Epstein-Barr virus, using reads of viral genomes that existing pipelines were throwing out as junk, and found that ~10% of people carry detectable EBV DNA in blood.
Carrying persistent EBV is associated with variable antigen processing, and the broader genetic architecture of viral persistence shares a component with lupus, rheumatoid arthritis, and type 1 diabetes.
Meanwhile, a separate line of very recent evidence is also pointing in that direction. The shingles vaccine, targeting another persistent herpesvirus, is showing ~20% dementia risk reduction in quasi-randomized studies which has been replicated across multiple countries.
There seems to be more at the intersection of immunity and age-related disease than we initially thought.

Came across this summary that pulls together some of the recent findings on the links between commonplace (including ostensibly "harmless") pathogens and long-term harm to human health. The war on infectious diseases is far from over!
So let me get this straight: COVID is a bioweapon that leaked out of a Chinese lab. But it’s also just a cold. But still a bio weapon. But we’re not going to do ANYTHING to mitigate its spread. Like not even filtering the air to keep a supposed bioweapon from spreading?
We know Covid is associated with a higher subsequent rate of autoimmune diseases. A new report from >1.7 million Singaporean adults concludes "Booster vaccination appeared to mitigate the risk of long-term autoimmune sequelae."
