To ask the obvious question, why was this not a thing at the start of 2021 after a year of lockdowns but only a thing at start of 2022 after the first year of jabs?
The same question might be asked why the militarty DMED medical reporting system for the active duty showed triple digit percentage increases in 2021 in serious issues but the numbers were steady from 2015 on to include Covid year 2021.
What changed in 2021? I think we all know. It's the elephant in the room.
