Teachers unions demanded closures and masks long after it had been crystal clear COVID risk to kids was near zero. Because they could (though seldom did) infect adults.
Now all the adults have been offered vaccination! Enough!
And "the CDC says" from the same entity that corrupted the February schools guidance, overruling science with politics. I mean, really???
Every age from 1 to 17 had an observed population fatality ratio of less than 1 in 100,000.
If we assume (based on latest UK estimate) that full mRNA vaccination lowers mortality 97%, unvaccinated children have mortality risk similar to vaccinated 30 year olds -- and far, far less than vaccinated older adults. 100 times lower than vaccinated 75+.
Should probably roll this back to an end date before the vaccine was available, but that would only make the point more strongly.
The original (much worse than reality) Ferg model that shut down the world estimated R0 at 2.4.
Classic SIR formula of HIT = 1 - (1/R0) at 2.4 yield HIT of 58.3%.
Israel first dose as of today (58.15%) is still short of that and positivity rate went under 1% on April 4. If we look two weeks earlier than that on March 21 Israel was at 55.72% first dose and 49.16% fully vaxed. And decline was steep earlier.
It is likely that very soon, perhaps today, Massachusetts and Vermont will be the first states to have a higher percent of total pop first dosed than Israel. And we likely have much more natural immunity than Israel from larger past waves. ~125 million Americans.
