New CDC report format (ongoing, currently from 16 jurisdictions - states or big cities)
Rates of COVID-19 Cases and Deaths by Vaccination Status
April to Sep 4 (One month behind to allow for correct coding)
Overall : Unvaxed 6.1 * chance of positive test 11.3 * chance of death
By vaccine : All better than unvaxed, but Moderna the best
By age: Very curious : 12-17 unvaxed has double the case rate of 80+ unvaxed.
If small sample given 80+ unvaxxed is small proportion maybe quantisation leads to downward error. Still unless down to 0 (and then there is no proper rate) i'd not expect this to be enough
