Wargame the scenarios. You wouldn't want to give one dose on purpose, but reserving a whole bunch of doses to prevent some people from getting only 1 in a worst case scenario is silly. That 20-70% efficacy number includes the entire period between dose 1 and 2. It looks way better 10 days after dose 1, btw-- MLE around 80%. e.g. single dose -- 50% efficacy (to be pessimistic); double dose -- 95% efficacy. 10M doses "…
I wonder if hitting the delivery targets of 20M per month is going to be achieved. That's the first bottleneck before the vaccine supply.
Lowering reserves would still increase administration rate immediately (though not proportionally). Actually, we might even enter phase 1B in some areas and have a mostly parallel administration system start to come up...
It's unclear to me how much of the slowness so far in administration (13.5% of doses allotted are reported as administered so far)... is A) (fixed?) delays in reporting, B) (fixed?) delays in logistics getting doses to administration sites, C) limitations on rate of administration, D) holiday-related slowness. Only C really matters in the long term-- if it is ramping poorly compared to production than that's a problem. But I think it's premature to assume C is limiting when A, B, & D are surely large right now.
