I'm a bit unclear what you are seeking. The vaccine was mass produced in 2020 via Operation Warp speed so it bridged 2 Presidents.
Protocols were changed in massive ways
With Warp Speed as originally implemented, the jabs were meant for only the elderly and people with serious health conditions that might make a case of CV-19 lethal.
Everyone else was supposed to get a therapeutic.
CV-19 was remarkably stratified - most people had no worries.
In fact, unvaccinated children being exposed to the virus was a huge lever for herd immunity
The WarpS legal exemptions were specifically conbstructed to make viable therapeutics the first option.
THAT is why the new hive went way out of their way to demonize therapeutics.
If they worked then the vaccine was on the shelf and less $$$
People were suppossed to be treated quickly when symptoms emerged.
Yet hospitals told people to go home and come back if they got worse.
People got worse and became hard cases - ended-up on ventilators when they didn't need to.
I knew a guy in quaratine who after 2 weeks was getting worse
His MD said "no" to HQ.
My said hje wanted the HQ and he was better and home in a few days
