At this point, the vaccination numbers are a mixture of phase 1A and phase 1B Tier 1 (65+), so it is hard to tease out the numbers. We didn't have clear numbers (that I know, anyway) for the first vaccinations at the end of phase 1A. It is also hard to understand delays in rolling the shots out.
It is clear that although the vaccines were in short supply, there were a lot of first doses that sat at vaccine administration sites (hospitals, etc.) in December.Â
The best I can say is that California originally predicted 2.5M people in phase 1A, but now estimate 3M.  We are now seeing phase 1A second doses being given (3 or 4 weeks after early January). Just under 500K people have gotten 2nd doses in CA. That's just 25% of the originally estimated phase 1A. (I believe very few of the 300K LTCF people in phase 1A have gotten their 2nd shots -- not because they refused them but that CA didn't get them to them.)
The US
originally predicted 21M in phase 1A. 4.7M have received 2nd doses (meaning 1 doses by about Jan. 1). Again about 25%.Â
These are totals, not per week. Remember, Pfizer 2nd dose is 3 weeks later; Moderna, 4 weeks later.
So, today's numbers (Jan 28) of 2nd doses represent Pfizer doses given through about Jan 6 and Moderna through Dec. 31.
Total 1st dose distributions by Dec. 21: Pfizer: 5M ;Â Moderna 6M
Total 1st dose distributions by Dec. 28: Pfizer: 7.6M; Moderna 8M
Total 1st dose distributions by Jan. 4:Â Pfizer: 9.7M; Moderna 10.1M
Someone probably has done surveys of phase 1A vaccination rates but I haven't seen it. I expect, for instance, Stanford Hospital knows how many of its staff has taken a first dose. That may be a different percentage than, say, healthcare staff at some skilled nursing facility.
It is an entirely different question about the rate of vaccination demand in the general population, and among them, the demand by different age groups.
And, of course, the anti-vaxxers in Marin County (CA) and in rural Louisiana may be very different.
Stanford hospital might be a good example for which I have data. There was
early data on their distribution. Their current information is
available .
The early posting indicated about 15K healthcare workers. Current posting indicates about 15K (Santa Clara + Alameda counties) have gotten both vaccinations.
The early posting indicated about 30K total population. Current posting indicates about 25K have gotten at least one dose (of 29K doses received).
The 15K of healthcare workers were in phase 1A. But I don't know the justification for the other 30K. It may have been improper for the state or county to give them enough doses to cover everyone at Stanford Medicine. (Maybe things like this is why the state raised the estimated Phase 1A from 2.5M to 3M.)
