What do you think the percentage breakdown is?
In an area with transmission occurring, what percent is from unvaccinated vs vaccinated?
Is it 90% unvaccinated, 10% vaccinated?
80%-20%?
50%-50%
95%-5%?
30%-70%, mostly from vaccinated?
Clearly there will be something, and it’ll be a percentage of the whole. So, in an area with high transmission, the vaccinated need to take more precautions. Since even if it’s just 5%, 5% of a really big number like FL transmission levels, is still a large raw number.
Which kind of exactly matches the current guidance. At a low transmission level, 5% of a really small number, is super small.
So, what do you think the split is? A 50%-50% split would make them both an issue to worry about at all transmission levels. I think the split is so skewed towards the unvaccinated being the driver, that it dwarfs the vaccinated's impact on spread. To the point that it only matters when spread is very bad. Of course, it’s very bad most places these days, not like FL, but not great.
I prefer the phrase “used lung air”. It matches the mechanics and reminds us of exactly how transmission is occurring.
