💉VACCINE DATA UPDATE (March 13)💉

🚨Record day of reported vaccinations, with 4.6M. 50% higher than past 2.9M record. Looking into why (data dump/lag, +capacity, etc.)

📊4.6M doses today; 7-day avg=2.54M/day
🇺🇸US: 106M doses total

⚠️This is a huge number that's 50% bigger than we've ever seen. it's possible there's some sort of data/methodological reason for this. We are investigating and will post a blog/more tweets if we find out something more.

In the meantime, <sportscenter voice> THAT'S A BIG ONE
There are some states here that are all having record days: Take a look at Cali, NY, Mississippi, North Carolina:
Whereas some states are essentially flat -- DE, WA
So, obviously, *something* is going on here. But it's still a very big report. Whether it's data lag or something else, it pushes the 7-day U.S. average (a far more important measure) up substantially.

We'll see if this is a trend or a blip.
Some possibilities:
-Timing of CDC data pull (they were later than usual today)
-FEMA/mass vacc centers bump (operational or data)
-State-specific backlog of data coming in all at once
-Something else....

Ideas/guesses welcome while we try and find out more.
And keep in mind, whatever is happening is happening *on top of* what's usually one of the biggest reporting days of the week.

☝️Regular reminder: These are counts of when vaccines are REPORTED, not when they happen.
Also, FWIW, it's not a J&J dump (at least not according to the vaccine breakdown CDC has up). That's only about +315k reported today.
WE HAVE AN ANSWER: Here's why today's number was so much bigger than usual (short answer: it's a one-time methodological thing)

Here's why the U.S. reported an absolutely massive 4.6M doses on Saturday (more than 50% higher than any prior report).

The boring answer: It's a one-time methodological bump from a later-than-usual CDC data pull that sucked in more data than usual.

bloomberg.com/news/live-blog…
This means (assuming CDC reverts back to it's normal data pull time) that Sunday's number will probably be smaller than it would be otherwise.

Here's my earlier thread taking some guesses at what's going on.

Our methodology blog post also has (from CDC) what the number today *would* have been with a normal pull time. You can find it here (it's still a lot):

⚠️Data note: We made a chance to our NYC methodology that brings it in line with the rest of the U.S. The % of people vaccinated now reflects residents, not place of vaccination. The resulted in a change to our NYC %s.
💉J&J doses continue to creep upwards.

💉VACCINE DATA UPDATE (March 6)💉

⭐️One-day record, almost 3M doses reported in the U.S. Mass vaccination sites like FEMA-run centers + stadiums may be boosting numbers.

📊2.9M doses today; 7-day avg=2.16M/day
🇺🇸US: 87.9M doses total

We'll be adding more granular data on J&J doses as we get it. We are hoping that will be on Monday.
For those looking for how many *people* have gotten first/second doses, that information updates with every mini-update here, just above the table:

💉VACCINE DATA UPDATE (March 3)💉

⭐️Our U.S. 7-day average is now 2.01M doses/day, the first time above 2M. This appears to be driven by a combo of winter-storm make-up doses + increasing supply.

📊1.91M doses today; 7-day 2.01M
🇺🇸US: 80.5M doses total

bloomberg.com/graphics/covid… Image
If there's a significant pull-back after the storm make-up bump, this could slip back down. But between J&J doses going into arms this week + rising shipments of about 15M doses/week, that seems unlikely/short-lived.

2M+ averages may be the new normal.

Also, uh, this happened and we still don't know what it is...
