See comment 47.
The article says that 97% of those treated were partially or unvaxxed.
It doesn't tell us if they were hospitalized, unless it goes into detail behind the pay wall.
Treated could be as little as going to the ER for a test.
We know from the TX demonrat fleebaggers and the Cape Cod outbreak, that the vax will not prevent infection, hospitalization or transmission.
Article posted on FR the other day claimed that 60% of hospitalizations in the UK are vaxxed.
