The 2nd dose needs to be in inventory tho.
I think they actually are making sure this is the case, since that is required by the FDA, but it is debatable whether it needs to be. The strategy here depends entirely on your confidence in the picture of future supply. (I am not suggesting a deviation from dosing schedule!)
In any case it’s easy enough to schedule people for a first dose, with an expectation of future supply, and if it doesn’t come through, just boot them and give to people who need their second dose.
What! Denise and I are something like 89K in line and they have only received 3000 doses. If that's not a shortage, I don't know what is. And this is just the wait for up to 1B.
That’s a shortage of people to inject your vaccine, or local non-homogeneity of supply, not a shortage of doses. Texas has about 1 million doses available, so there is no shortage of vaccine.
In general, the exact picture here is unclear, and that is not a surprise. But as far as I can tell:
Moderna and Pfizer will be delivering 10-11 million doses each week right now. With a ramp up leading to 200 million delivered by the end of March (that is the contract terms I have heard). Right now we are injecting less than 1 million doses each day.
So there is no shortage of vaccine, and no reason to hold back second doses (though I suspect they are actually doing that in many states, due to lack of clarity on future supply). This is non optimal.
We should inject as many people as possible ASAP, and strictly comply with the dosing schedule. These two things are not incompatible. In parallel perhaps they can do a study of alternative vaccine dosing schedules. But right now there is no reason to deviate from it, since there is no shortage of vaccine.
Again: note “no shortage of vaccine” does NOT mean that demand for a vaccine does not exceed supply! Demand for the vaccine most definitely exceeds supply, yet there is no shortage of the vaccine. Strange but true!
It’s an important distinction, because it informs how to proceed with dosing, who to schedule, what to focus on, etc.
