https://abs.twimg.com/emoji/v2/... draggable="false" alt="👓" title="Brille" aria-label="Emoji: Brille">I& #39;ve been watching the U.S. vaccine rollout every day for the last four months. It started slow, gained momentum, took off like a rocket and has likely now peaked.

https://abs.twimg.com/emoji/v2/... draggable="false" alt="⚠️" title="Warnsignal" aria-label="Emoji: Warnsignal">Success going forward is going to look very different. The metrics from March are not the metrics for May.
In March, we saw many states with 90%+ of delivered supply used. That was very efficient vaccine usage, but also tight supply.

Those % figures are now falling, as they probably should. Tight supply is not what you want when you& #39;re targeting harder-to-reach/convince populations.
The Biden admin says they& #39;re pursuing a policy of "overwhelm the problem". That means:

https://abs.twimg.com/emoji/v2/... draggable="false" alt="💉" title="Spritze" aria-label="Emoji: Spritze">Lots of vaccine sitting around, ready
https://abs.twimg.com/emoji/v2/... draggable="false" alt="🏪" title="Gemischtwarenladen" aria-label="Emoji: Gemischtwarenladen">At lots of locations
https://abs.twimg.com/emoji/v2/... draggable="false" alt="📆" title="Abreißkalender" aria-label="Emoji: Abreißkalender">Many open appointments

If you saw that in March, you& #39;d say "this is a failure." This is a different point in the rollout.
The Biden team was very happy, as were lots of people, about big dose numbers a month ago. Here& #39;s how they& #39;re talking about it now, which more or less matches w/ my read:
“Going forward, we expect daily vaccination rates will moderate and fluctuate.”

“We’ve gotten vaccinations to the most at-risk and those most eager to get vaccinated as quickly as possible."

“It’s OK if there’s not a long line of 1,000 people... That’s good, that was the plan.”
I think that& #39;s correct. It doesn& #39;t mean there& #39;s not a lot of work to do! It just means that work, and the numbers, look different.

"Mass" vaccination is useful when you have a huge mass of people who all need and want to be vaccinated at once.

What& #39;s next is more boutique.

There is some very good news here. There are a LOT of people who have gotten their first shots. Almost all of them seem likely to complete their second. (I know there& #39;s a sort of doomsy piece in the Times today, but... it& #39;s still 92% completion)
Right now, the U.S. is about where Israel was in mid-Feb. (This uses our apples to apples "enough for X% metric, which helps create good comparisons).

They kept vaccinating after that point to about 50% of their pop. (and are now at ~60%).

Look at the case curve.
(The usual caveats: The U.S. isn& #39;t Israel, etc etc etc)
I hope this helps people as they think about how to read the numbers going forward. In short:
