It would be nice to have good info ...
Hospitalized due to Covid, but ...
Percent not vaccinated at all ... 60%, got it.
Percent not fully vaxxed (with appropriate immunity build period) ... ???
Percent fully vaxxed, but got Covid anyway when they were expected to have immunity ... ???
But in the scheme of things, none of this probably matters much. They watch the not vaccinated, because they want everyone vaccinated. They probably don't worry about watching the fully vaccinated group, because they can't do anything about the effectiveness of the vaccine. That group is only important to them if they want to know if one vaccine is better than another.
