My mother was just diagnosed with an autoimmune disorder after being healthy her whole life. Main difference, she got the vaccine and all the boosters.
Decided to see if anything was linked to the vaccine and found this study proving without a doubt the vaccine caused it.

These people responsible need to pay
My mom just got her second booster today, it sucks but they are choosing this themselves. It feels like every time she gets injected is like playing Russian roulette. So far, so good but I am always bracing for some bad news like you are unfortunately getting, or worse.
