I had the J&J last spring and it also kicked my ass for at least a day, with even some mild drowsiness and aching 2 days later.The J&J booster I received Monday afternoon kicked my ass from Monday night through most of Tuesday. No complaints. I'll gladly get in line if and when another round is necessary.
I’m opting to go with the Pfizer for my booster next week. How was your reaction to that one?
