[FRIAM] vax v unvax

Wonderful.

The Morris article checks pretty much every box I would have thought to ask for.  The Conclusion section is like the last 15 pages of the musical score to Oklahoma.  As my first-cellist student friend once commented, half in despair: “Then you get to the finale ultimo and there’s still more!”

You know what caught my eye, though, was the efficacy numbers in Morris’s 6th and final table.  

There is a thing we know about Gompertz distributions of morbidity and mortality.  These are the distributions that say (originally for mortality, but there are similar patterns in morbidity) that the frequency (and, from sampling that, to some extent the diversity) of things you get sick or die of increases exponentially with age through the lifecourse, esp. if you can correct for things like violent death among the young that tend to add a constant component.

But, for humans somewhere in the 80-90 year age frame, that exponential increase seems to stop.  It’s not that people’s morbidity and mortality drop off, as if the survivors are somehow supermen: they continue to get sick at the full diversity and rate of the top of the exponential curve; it’s just that that rate levels off and remains roughly constant.  I think I have heard numbers like 1/3 die per year in that late plateau stage.  That seems a little high, but not wildly off: for every 10^5 people at age 90, there might be only one surviving to 100.  

Anyway, it is at that termination of the Gompertz exponential that we see this sudden increase in survivorship among the old and vaccinated.  I wonder if the two are somehow related, and if, within what we already know, the correct statistical model is defined, or if there is some other variable we would need to measure.

I claimed that the majority of hospitalizations are the unvaxxed. She claimed that down near her (I think closer to Centralia, WA), it was flipped, that the majority of hospitalizations were vaccinated. We had the usual conversation where she ended with "you believe your data and I believe my data" blather. So I decided to see if I could find news articles claiming the majority of hospitalized covid cases are the vaccinated. And I found this:
