I am unvaxed. I won’t get the vaccination either. Call me a coward but why take a shot for something I am almost 100% going to survive?
The risk reward is not there. You get the vax and you can still get sick. You don’t get the vax and you can get sick. Maybe the symptoms will be worse if I don’t get it. But stats are showing that not to be the case.
But who knows since science is no longer a priority for this adim when it comes to anything.
Now that you've had it, you've got the antibodies.
Should be good to go. I'm not a doctor, nor do I play one on the Internet.
I ain't vaxxed, either. And if I get it, I'm sticking with my antibodies if I survive.
Was your coworker vaxxed? Is that why he didn't show symptoms?
BTW, congrats for riding it out! 
When you were fasting, were you hydrating? Saw something today where they said hydrating helps move your immune system cells to the battle.
Dehydration apparently slows them down (no lubrication?).
