I’ll admit that I didn’t understand the difference either.
However how do they go about estimating how many would get COVID with no vaccine?
Over a year and there have been 32 million cases (I should have stopped the clock before the vaccines were released).
Ca. 330 million population in the USA, so 10% would be absolute maximum. Surely people have more interactions over the course of a year than they do over the course of a plane ride.
However it could be a lot less than 10%.
Also do they look for antibodies, rather than actual infection? Are they able to find natural resistance?
I realize it would be a lot harder to find volunteers to take the vaccine AND be deliberately exposed to COVID.

————simple really, everybody is going to get Covid, and everybody is going to die, and the masks will help you only a little, so wear your masks forever, even when you have been ‘vaccinated’, because Science. And Math. /s
How?
The same way they get all their other numbers.
They pull them out of their a$$es.
