Just a footnote, I had the tetanus shot one week ago, since then I've developed a bad case of bronchitis (I think I had the beginning of a cough before the shot.) Also at the point of injection by my shoulder, my muscle is hot and has swollen and I've been having pains in the shoulder, elbow and especially the wrist of that arm. Personally, I feel like crap. I am suppose to have three Hep B shots yet and any others that might come up negative immunity in blood work. I live in Canada and don't think I can fight this.
