Well spotted! Always frustrating to see "snapshot" analyses, which often result in "wait 2-3 weeks to flip the results" but by that point, the propaganda has run its course.
If the vaccinated and unvaccinated nations were randomly allocated geographically, it might not be as outlandish - but in this case where Eastern Europe is clearly the unvaxxed category, all you need is to wait for the timely wave, as East mixes a lot more with the East than the West (relatively contained, for the time being)
Even in this snapshot however, if you look closely you can see amusing tales:
- Belgium (89% vax) and Slovakia (54% vax) have equal covid deaths
It's just a coincidence, of course.
