Seems to me it depends on location and how well they can staff it as to how many vaccines can be given in one day. Here is tiny Culpeper, they use a college auditorium and give 600 per day. I see they opened a facility at a ballpark in NYC that can do 5,000 a day at that one location -- but they only have vaccine enough for 200 per day. They just opened 3 sites in Dallas which can do a combined 10,000 shots per day, but again, no vaccines. And we have thousands of Walgreen's and CVS all over the country that want to give vaccines, but no supply. So it seems we are getting the delivery down pretty good -- and could do probably several million a day in all the US jurisdictions -- we just don't have adequate vaccine at present.
