A question I'm not an antivaxxer , I've just had my booster today. I have the flu jab every year , Hep B , every jab I've been given I take it and not had any ill effects but the COVID jab is something else. My first one I got a big red rash and the skin went all leathery , my second one I felt like death warmed up and this one my arm feels so sore and I have a massive head ache . Can anyone with knowledge tell me why the jab makes me feel so poorly compared to any other vaccine I've had ?
