JAIHole- FYI- Got 2nd Pfizer shot Tues. in left arm this time because of rotator cuff problems in the right. Just a little soreness at the injection site today and a little increase in sinus congestion but that's it! But my wife had a severe headache all night. So much for side effects, some good and some bad. Still a hell of a lot better than the alternative! Wish all would go for it so we can get out of this mess!
