Well, they both experienced waves immediately after being the highest vaccinated in the waves. Why do you assume the unvaxxed have spread covid in the NL (with all venues closed since mid December this has kept most tourists away) rather than the planes from SA that were still landing well into early December and the short ban, ca 10 days, was lifted on 22/12?
The figures have been going down in hospitalization now that Delta is coming to an end (serious covid cases are usually about 3 weeks in hospital).
