Interesting...
The data set looks to have two different subsets (>75% vaccinated and =< 75% vaccinated). And I think that the latter subset consists of the poorer EU countries. Makes me wonder what other predictor variables (per capita income, median number of comorbidities, median age, etc.) ought to be accounted for.
To put the numbers in perspective, in the US ~34K/yr people die of the flu (average of the estimates for the past 10 years) . With a population of ~330M, that works out to an annual ~103 deaths/M. Divide that by 26 (approx. number of 14-day periods in a year) and you get a 14-day average of 3.9 deaths/M. However, flu season is notionally only in "cold months"; let's assume that it is ~6 months (1/2 year). That puts the 14-day average at 7.8 deaths/M.
For the >75% vaccinated countries, the average of the 14-day average is 10.6 deaths/M, with a median of 9.5 deaths/M.
For the =< 75% vaccinated countries the average of the 14-day average is 127 deaths/M, with a median of 75 deaths/M.
Also, in the US, the average annual number of deaths in automobile accidents is ~35K/yr.
Let me know if you find a conceptual or math error.
