Second, it went under the radar because it's probably not attributable to the vaccine. The people who died were over 80 and already extremely frail with pre-existing conditions. They either died from those conditions or from their inability to cope with the mild side-effects of the vaccine, which everyone already knows about. Death rates in Norway are well within the historical range, so it's fairly likely that there were no excess deaths caused by the vaccine at all.

Their dying after having the vaccine does not mean they died because of the vaccine.

But anyway, “frail elderly patients” have a tendency to have a short life expectancy whether there is a pandemic on or not. The thing they will have to sort out is whether those 23 are coincidental or not. Ie what number would we have expected to die, had we not vaccinated them. This is pretty elementary statistics and I expect that they’ll sort it out shortly.
