Hello, I have autoimmune disorder and had the COVID vaccine. The first one left me with only a sore arm. The second one made me feel like I was 200 years old. I hurt so bad and was severely fatigued. I did not run a fever or notice anything else. This only lasted about 24 hours. Not sure if this was normal for the vaccine or if it exacerbated my current condition. I lived through it. I can't say what others would feel. We all know everyone is different.
