First, it was 33 people out of around 50,000 elderly and vulnerable people who were vaccinated. Your source is outdated.
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.
To reinforce this, one of the statistics that the beeb have wheeled out is that in the most vulnerable group being vaccinated (in the UK), aged 80+, one in ten of them will die regardless of covid in the next year. Quoted from "How to vaccinate the world -- Vaccine Hesitancy" [0] from 12 minutes in to 15 minutes. (And because it's BBC sounds, for some reason it randomly skips episodes when I load the page).
The entire series is well worth a listen, data driven and statistics heavy.
