Re: How did 8 fully vaccinated NY Yankees catch covid?
"Kind of makes you wonder if there is some under reporting of breakthrough cases."
Well, CDC have said they are not going to report most breakthrough cases. So I don't think you have to wonder if they are under-reported. They are, for sure, systematically and institutionally underreported! ;-)
On the other hand...don't let yourself get fooled into thinking that all breakthrough cases require hospitalization. That's just a quirk of CDC reporting.
