In Plymouth they scheduled my 2nd Pfizer dose exactly 4 weeks after the 1st dose, even though there are earlier appointments available. Walgreens was chastised by the CDC for the same practice and they stopped doing it. I wonder why the Plymouth site is doing this. I'm not saying any harm was done, I'm just wondering why they wouldn't follow the recommended interval.
My bet it that it is purely logistics. When they give people either Pfizer or Moderna, they schedule the 2nd shot 4 weeks out. If they didn't do this, Pfizer 2nd doses at 3 weeks would start happening at the same time as Moderna 2nd doses at 4 week intervals. They don't have the facility space or staff to do double duty. Since it doesn't seem that the time window is critical at 3 weeks, it's just a lot easier to do it this way.
