As an aside, I feel better this morning. I got my second shot of Pfizer vaccine on Monday morning, felt fine all day Monday, but began feeling bad on Tuesday evening, which was a surprise. I had flu-like symptoms of aches and pains all over, being very low energy, and lots of GI symptoms, which have all improved, but the GI symptoms seem to be hanging on. I still feel lucky to have received the vaccine, and the side effects that I have had are much better than getting Covid. So there's that. I wish you could talk your mother into getting the shot. She is someone who would certainly benefit from having it, and the side effects in people her age seem to be greatly reduced since the elderly have a less robust immune system reaction. I am 70 (so elderly!), so I was a bit surprised at my side effects. I thought they would be less than they were. My 74 y.o. husband only had a sore arm. Good luck! I hope you don't have any side effects and a great experience.
