I got the flu/pneumonia shot until four years ago because of the hype. Two years ago, I got the flu, then bronchitis, then I got sick as heck from pneumonia. I went back on the shots, and haven't been sick. However, one of the shots in my right arm, caused it to turn red and swell from my shoulder to elbow, and hurt. It lasted about three or so days. I didn't like that, but I guess it happens from time to time.
