You’re killing me.
Not my area, but I looked at it, and it seemed properly applied as best as I can tell.
I would consider 3 things.....
1) Given the political nature of this topic these days, I would want more specifics on their specific data sources.
2) A similar study on the effects of shut down would be interesting to pair with this for overall consideration.
3) while the spread has been slowed successfully, it will nonetheless reach virtually everyone eventually, so the real estimate to look at is lives saved ( high risk people who avoided exposure and got vaccine who would have otherwise died ) rather than simply prevented infections.
When that much smaller cohort is compared to deaths from the shut down consequences, I strongly suspect the cure will be found to be much worse than the disease ever was.
Interesting study. Thanks for posting it.
