Key feature of the Delta variant is everyone needs both shots of the mRNA vaccines to be protected

But national vaccination data suggests about 10% of people have missed their 2nd shot

That's about 18 million people

And those 18M aren't spread evenly across the US

thread

So some math

As of today, there are 29M people with 1 shot

Based on daily vaccination rates, about 11M of those 29M are in window between 1st and 2nd shot

Leaving about 18M people who missed 2nd shot.
That's 10% of folks who started getting vaccinated

But....

People missing 2nd shot varies widely by state

In Hawaii, nearly 1 in 4 people who got their first shot missed their 2nd shot

Utah is at 20% of people missing their 2nd shot

IL (18%), PA (16%), and Arkansas (15%) round out worst 5

So who's good?

3/5

Iowa best with only 5% missing 2nd shot

Next are Ohio (5.3%), Louisiana (5.7%), Maine (5.7%), Nebraska (6%)

Interestingly, no correlation between underlying vax rates and missing 2nd shot

That is, high vaccination states have comparable proportion of people missing 2nd shot

So what does this all mean?

First, a lot of people (18 million) have missed their 2nd dose

That's bad when Delta variant is around

Second, some states have far fewer folks missing 2nd shot

Iowa, Ohio, LA are among the best

We should learn what they are doing

5/6

Third, we must focus more on helping people get their 2nd shot

Explain why its important
Make it easier (give people day off!)

And have a clear message to those who missed their appointment:

Don't worry why you missed it

Better late than never.

Go get the 2nd shot
