I have an older vaxed friend who has multiple symptoms of disorders caused by the vaxes/boosters she got. All are prominently circulatory problems. Her hands turn white due to blood flow issues. Yet she steadfastly denies it is connected to the shots and she defends the utter necessity of getting them. I'm pretty sure she'll die a bit earlier than would have happened. She's having kidney problems; not a good sign.

If the immune system is damaged I expect to see signs of such things as increased fungal infections (more people getting toenail fungus will be a warning, for example. It sounds trivial but it can be a sign of systemic fungal infection, which is much more serious. And there's candida, and more.))
