PBS: Coronavirus Delta variant 'may hit us pretty hard' this fall.

32. While it's clear that the fully vaccinated don't, at this time, get as sick and perhaps don't

get infected at nearly the same rate as unvaccinated...but I believe it's still an open question what the true rate of infection is among the vaccinated. If there are no symptoms among the vaccinated, there's no reason to test. And without testing we don't really know if we carry the virus and transmit at some level above 0%.

So I believe it would have been more accurate to say 'The case rates are going down because the vaccinated people are not getting infected...at the same rate as the unvaccinated'

And we don't know if there are long covid reverberations among the asymptomatic and mildly symptomatic with Delta. Just hasn't been enough time to know, and that's something about covid19 that's been true all along...there's a lot we don't know and we are always playing catchup, weeks behind the trend (to paraphrase Fouci).
