As I write this, it has been nearly 30 hours since we each got our shot. So far, so good. Scott's arm is hurting a bit at the injection site, but not too bad. I have not had any arm pain. We both have had a headache today.
The big thing has been that we both have been very tired today. Neither one of us slept very much last night. So, how much is the lack of sleep and how much is the shot, we do not know.
If this is the worst of it, we are very happy.
