Oh, right! Thank you.No, it's not that interesting, because that isn't a report of all cases of breakthrough infection. It's a report of all cases of breakthrough infection that involved hospitalization or death.
What is interesting is that of the 6000 reported fatal or hospitalized "breakthrough" cases reported to the CDC, 74% of them were people >= 65 years old.
The stat that doesn't make a lot of sense then is how are 20% of people hospitalized, but asymptomatic?
