Just got my Moderna Booster shot. I feel pretty good so far. I don't expect to have any side effects as I didn't have any with the first two shots. During the process of giving the shot, I yelled for no apparent reason just to mess with my friends over at the Lee University Health Clinic. I did learn that the booster shot is only a half dose of the others previously taken. That news further solidified my thoughts around not having any side effects, but we will see.
