All of these are issues that have been around, though SADS is a new term. I would say SADS is just sudden cardiac death, which is also nothing new. Question is, are the rates going up in the vaccinated population? Going to be hard to pin down concrete stats because the gov lies, there are no clear lines between the vaxxed and nonvaxxed population, and I would guess all of the above are most certainly being underreported. Well, with the sole exception of monkey-pox, but that seems to be a rump-humper issue.
