Did you have any side affects other that a sore arm? My wife didn't with her first jab, and is due for the second next week. She is early 60's, but I'm 71 and take zinc and vitamin D and other than medicine for high blood pressure I have no underlying conditions. BTW, since I have been getting flu shots, I haven't had the flu in years. Watching closely.
1st shot - sore arm for a couple days
2nd shot - mild fever/chills for one day
