I don't think that's true, and I can't really find numbers that say it's true. all I see is
> Dec 31, 2020 — Only about 2.8 million Americans had received a COVID-19 vaccine going ... of December, putting the United States far short of the government's target
So for the first 17 days of having a vaccine at hospitals getting shoved into peoples arms, that's 164000 per day if it was averaged out. But it most likely was a buildup increasing each day.
Still there's this from January 5th:
> The U.S. could soon be giving at least a million COVID-19 vaccinations a day despite the sluggish start, Dr. Anthony Fauci said Tuesday
and
> According to the Centers for Disease Control and Prevention, roughly 4.8 million doses of more than 17 million delivered had been used by Tuesday morning
Tuesday, January 5th I believe. So from Dec 14th to Dec 31, 2.8 million
Dec 31 to January 5th = 2 million
Biden may not have needed to do much to get to 1M/day, but for whatever that arbitrary milestone is worth, it seems like it was his to achieve. Trump couldn't even admit 400,000+ people died in one year from it. He can't claim some fake award for vaccinating 1M/day.
