I got my 2nd booster (Moderna) earlier today. It was at a city run site. The same place I got my first three shots. It was by appointment only. When I arrived, other than the staff, I was the only person there. While I wss waiting the 15 minutes after the shot an older woman arrived to get vaxxed. I was surprised it wasn't more crowded, since the age has dropped to 50+.
