_Are_ there unvaccinated over-65s in Denmark? AIUI it's generally a bit ahead of the EU curve, and over-70s are generally done in most European countries.
What can differ is which groups are vaccinated, e.g. Sweden has 19% vaccinated with at least 1 dose but the coverage by age group is e.g 85% in 80-89 and just 35% in 70-79 and 60-69 is only 10%.
