Had first Moderna shot 5 days ago, have not had COVID. Local arm soreness about 50% of tetanus shot for about 48 hours, nothing to worry about. Slept a bit more than usual for a couple of days. The day after, I had just a bit of that "hit by a truck" feel you can get when you have actual influenza, but maybe only at 25% of typical flu levels. No other symptoms. Easy.
Aurora, big Milwaukee area medical syatem, had hundreds of available appointments daily across their system. They had two appointments sscheduled every 15 minutes and had sis, yes SIX, nurses there to make it happen. Two at the greeting table. And two at each of the two tables set up to serve individual patients. All were actual nurses as all had badges saying so. Oh, almost forget, they also had an RN in a supervisory role. So, they staffed it up with 7 nurses to do 8 shots per hour. I will say all were professional, knew what they were doing, and the atmosphere was calm and mellow.
