> Far more people are getting infected but our hospitals are not (yet) being overwhelmed.

That makes sense. I think it's clear that vaccination makes the infection less severe and reduces hospitalization rates. But there's also a hope, which is the basis for a lot of policy decisions, that vaccination will reduce the chance of being infected, perhaps even eliminate the illness, and Iceland's data doesn't support that.

> If you read further down in the statistics data there is a breakdown by population age.

Only for isolation and for cumulative cases, not for current cases.

> You need to take into account the COVID is less infectious for the young.

Source please. I haven't heard that before; though it is less severe for the young.
