You can sometimes even see this effect in one country, if all the old people are vaccinated and none of the young people are, you'll still probably get more COVID deaths per old person. If you just look at mortality by vaccination status you'll see lots more COVID deaths in the vaccinated cohort, but that's because the vaccinated cohort is just old.

East has low vaccination rates and high excess mortality, north has high vaccination rate and low excess deaths.

Africa and South America could be different effects. I don't know how thoroughly they do, can or want to track excess deaths.
