So that's interesting about holding back the shipment itself. To my knowledge that hadn't been mentioned before. Just that the amount sent would be for X number of people when considering 2 doses.
Like the wording from my state, which is still assuming EUA is granted, was "Kansas’ 23,750 doses from Pfizer won’t cover the 40,000 people in the top priority group. Each person needs two doses, so only about 16,875 people in the state will get immunized. Missouri’s 50,000 will take care of about 25,000 people." Both of those numbers are from the first shipment and don't include the numbers mentioned for by the end of the month. But that wasn't official communication from either state saying that's what they will do either depleting the full supply they get and then circling back or if they will only vaccinate about 16,875 and 50,000 people respectively despite the wording saying "will get immunized".
There was a discussion on the other thread where Dr. Gottleib I guess was saying basically to deplete the shipment even with a small risk of a subsequent shipment with doses (that would give the first people their second dose) not making it in time, but another article mentioned experts saying it was critical people get the second dosage due to effectiveness (which would cast doubts on the depleting supply) but now Pfizer has come out discussing the effectiveness based on 1 dose. Seriously it's a bit like whiplash here!
This seems like something that could vary all over not only in the U.S. but also throughout the world how they will handle multiple doses. I'm actually intrigued now how different places will do this. One of my biggest concerns is consistent shipments that arrive in time for the second dose (21 days for Pfizer, 28 days for Moderna) and of course hearing about the U.S.'s issues with the amount they purchased from Pfizer is putting doubt on that, that's why your mention of holding doses in reserve would actually work out. The concern of people only getting 1 dose and unable to get the 2nd dose because there aren't any supplies available at that time wouldn't be there so long as the doses meant for the second shot stay specifically in reserve for the people who got it the first time.
Sorry..I know kinda rambling here hope I'm making sense

On a random note apparently my state will have 5 to 6 distribution centers located throughout the state though locations of such have not been disclosed. I will automatically assume one will be in my area simply because we are right by the major airport in a very populated area with easy access to the main highway that feeds east to west of the state and we are a big rail and trucking hub but of course I can't confirm that.
