My wife was wiped out with the flu symptoms and sore arm for almost a week and I had large hives occur from the beltline up my back to about my shoulders that lasted for almost two weeks after the first shot. The doctor said it would behoove us both to skip the second one. This was only a few months ago.So it seems the shingles vax reactions are sorta like the Taco Bell dinner plate...........your either OK with it or it tears you a new azz.
