I'm not a doctor or scientist but I suspect adding adjuvants within the vaccine to promote a bigger immune response confuses the immune system. The immune system reacts to the vaccine components and fights them off, then remembers the response. But when the body finds more of that particular item again in the body, but in an innocent situation, it fights "the enemy" off. But perhaps that was just a protein that the natural body uses or needs. For instance, peanut oil was used in childhood vaccines in the 70's (and later??). Then peanut allergies went thru the roof. I suspect that the immune system found peanut protein as enemy material and went overboard in response to it. There are so, so, so many auto-immune system diseases now, I hardly know anyone who doesn't have a couple. It's the real pandemic, in my opinion.

This is a list of autoimmune diseases, comorbidities, and syndromes
