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.
That's your reason for refusing the vaxx, and it's a good one, but it is not persuasive to those who don't care. You're making a moral argument to those who have none.
The argument also fails if the vaxx can be made with no fetus cells. But really, you do not have to justify your choice, because in the end it is yours, and only yours.
