I don't know if this is the answer Gracie. It is interesting though.
I have never had a flu shot. I had the flu once in my life. I believe it was just about one of the worst illnesses I've ever encountered.
Doctors told us otherwise; but I know with all of my heart and soul that my Mom got pneumonia after receiving her pneumonia shot. She had acute diabetes and ended up in ICU in a coma. She'd never had the flu or pneumonia before in her life. She got pneumonia about three days after getting her shot.
