he says there's a 13% test-positivity rate. that's high. and he said, 90% of hospitalizations are unvaccinated people. but that means 10% of covid hospitalizations are among the vaccinated. he thinks that comorbidities are a factor, here. but that's got to worry you, no? >> sure, absolutely. you know, the breakthrough rate for most vaccinations, when you have the flu every year, it's not uncommon for people to -- to come into the hospital after vax -- after they have been vaccinated. a lot of it has to do with age and comorbidities. but that number of -- of admissions, you know, 80 to 90% of unvaccinated patients. that's really astounding. there's not much in medicine that's 80 and 90% and that's telling us something. this fourth wave has told us what we need to know about the pandemic. um, the first couple of waves, maybe, we could get away with not paying attention to this. this is a serious statistic. anything above 80% is -- is very telling.
