Emphasis on current phase in our state that is targeting people 65+
A catch-up

1/15
We're now over 1.4 million people vaccinated, almost 8% of the vaccine-eligible population (16+ years).
Almost 158,000 have received both doses (0.9% of vaccine-eligible population)
There is big variation in vaccination rates by county, but WHY?

Well, the primary determinant of different vaccination rates by county is:
(1) counties have diff population age distributions
(2) since the most impactful phase (in terms of volume) thus far is the focus on those 65+ years
We have vaccinated >21% of 65+ statewide.

When we look at statewide trends over time, by age group, we can see when the 65+ phase kicked in

But, when we take today's # (based on data as of yesterday), & sort counties by the % of the 65+ pop they have vaccinated, there is big variation, from 8.8% to 44.3%.
I know population estimates don't account for snowbirds, but that's not driving these diffs.
Again, why?

Well, some things make perfect sense, like:
The more people a county has that is 65+ years, the more people in that age group that will be vaccinated (strong positive correlation)
Both axes are on log (base 2) scale due to skewed pop data across counties...

It also makes sense that counties with a higher % of their population that is 65+ will have a higher % of its vaccinated people who are 65+.

BUT, we see that counties with more people 65+ who need to be vaccinated (bigger populations) have proportionately fewer people 65+ who end up getting vaccinated.
But a county should get more doses if their populations are bigger (which they do)

But is a county's dose allocation by the state dictated by:
(1) their overall population size (all ages)
(2) their population of vaccine-eligible people (16+)
(3) their population of 65+ since most doses will go there

It's important because there seems to be a strong inverse (negative) correlation between the % of a county's population that is 65+ and the vaccination rate in those 65+
In general, higher % of 65+ pop, lower % of people 65+ who have currently received 1+ doses.

I thought this might be impacted by counties with large nursing home staff and frontline healthcare workers since they were part of the first phase and would have included many people <65 who "consumed" allocated doses (not as much left for the 65+ phase)...

But, O do not see a strong county-level correlation between the % of the 16-64 population who is vaccinated and the % of the 65+ population who is vaccinated.
If the previous tweet were true, I might have expected a slight inverse association.

I don't have (or haven't taken the time to track down) population estimates for healthcare workers by county or I would've compared that to 65+ vaccination rates (instead of % of the entire 16-64 population vaccinated).
13/15

Clearly, right now, everyone in these counties is trying to get as many doses in the arms of people 65+
But whether these county-level diffs in 65+ vaccination rates are due to distribution issues, logistics, vaccine hesitancy, reporting delays, etc., etc., I do not know.

Last, I oddly still feel like crud, but tomorrow's a new day. I can't remember the last time I felt this bad for this long (obviously been blessed with excellent health).
Yes, I did get a COVID PCR test (my wife, too).
Both negative.
