I have had both shots. I was rather surprised to get in email from the major hospital system (Beaumont, for shoes of you in SE Michigan) where I had surgery a couple of years ago, inviting me to make an appointment. I had to activate the MyChart with them, but once I did so, I was easily able to make an appointment, and made the second one right after I got the vaccine. It was all fairly simple.
I have had absolutely no side effects whatsoever, except a sore bicep for about 24-26 hours after, but that's to be expected from a shot.
