The >65 population in Scandinavia is largely vaccinated already, and incidence of new cases is low. So it's a decision that might be questioned, but which would have small real-world consequences even if it turned out to be incorrect in isolation.

That part of the decision might just be the combination of uncertainty combined with the public's skepticism towards this particular vaccine. Giving an impression of listening to the public might have been considered a better overall choice than making a big communication effort for little real-world benefit. Other vaccines will be available very shortly for the few >65 people not yet vaccinated.
