Lack of FDA approval was just a convenience. I see many asking for links and other info on FDA shortcuts and other talking points to justify still not wanting the jab.
It was never about FDA approval (or lack thereof). It was always about a >98% survival rate - for a cough.
The argument is 1) you have an immune system, 2) you believe in natural immunity, 3) the substantial list of documented side-effects doesn't outweigh a 2% chance of dying from covid.
My only qualm ever was and has been that we don’t know the long term effects of modifying your RNA.
Unless they have a time machine, that’s not changing any time soon
