I become very ill for 2-3 days from flu shots; also was very sick last year from the pneumonia shot, fever and all. Then several months later I got the flu. I’d rather have the flu than what I go through from the shots.
You might need to see an allergist. Your problem is not the flu or pneumonia shots, per say. Dead viruses cannot make you sick. You are allergic to something else that is common to both. If it were me, I would like to know exactly what that is so I can avoid it in my other walks of life.
