Earlier quoted context omitted.
I am so sorry for your terrible sickness! It's probably impossible to say whether "the vaccine has kept this relatively mild", especially since you got it despite being vaccinated twice. At least earlier strains showed no or very mild symptoms in 80% of the infected, and yours doesn't sound very mild. Maybe you'd be dead if not for the vaccine? or perhaps the vaccine allowed your body to contain it to just your nose,…
> yours doesn't sound very mild. Yes his symptoms sound mild. There's a good chance that whatever you think of as severe cold/flu is all clinically mild (unless you've actually had complications and wound up in the hospital). Actual unvaccinated severe COVID-19 is an order of magnitude worse than what you can imagine as severe.
“Order of magnitude worse” of disease severity isn’t defined super clearly, but if I heard that description compared to the worst cold/flu I’ve had that didn’t hospitalize me, my feeling would be that the result would be fatal.
