As of yesterday AM, ~2.8M people had received their first dose, while ~12.4M doses had been distributed to states. The 12.4M distributed is the Feds' side of the effort; the 2.8M is the states' side of the effort. The MSM and Prog punditocracy are blurring that distinction, Because Trump.
As of January 4, 2021, 9:00 AM ET:
* 15,418,500 doses of vaccine have been distributed to states;
* 4,563,260 people have received their first vaccination dose.
As I pointed out above, the original OWS goal of 20M doses distributed by the end of 2020 might have been met but for FDA dawdling. Certainly, given an extra week or 10 days of distribution, reality would have exceeded the ~60% of goal that in fact was accomplished.
What is currently a CF, in most states, is getting the vaccine doses to people. Some states, e.g. the Dakotas and Connecticut, have injected more than half the doses they've received. Other states ... their governors should be inventing invective trying to extract explanations from their "public health" bureaucrats!
