The correlation between COVID-19 deaths per million of population and 65+ year olds that have received influenza vaccines is real. Dr. Allan S. Cunningham presented the challenge and here are the results.
One source for vaccine data: OECD (2020), Influenza vaccination rates (indicator) doi:10.1787/e452582-e (Accessed on 21 May 2020). This lists, by country, the % of the population aged 65+ for 2018 or the latest available year. For Covid-19 death rates by country as of 21 May 2020: www.worldometers.info/coronavirus.
% INFLUENZA VACCINATIONS IN THE ELDERLY (x) /COVID-19 DEATH RATES PER MILLION (y)
Czech Republic 20.3/28 Lithuania 13.4/22
Denmark 52.0/97 Luxembourg 37.6/174
Estonia 4.8/48 Netherlands 64.0/337
Finland 48.4/55 Norway 34.4/43
France 49.7/431 Portugal 60.8/125
Germany 34.8/99 Slovak Republic 13.0/5
Hungary 26.8/49 Slovenia 11.8/51
Ireland 57.6/319 Spain 53.7/596
Italy 52.7/535 Sweden 49.4/384
Latvia 7.7/12 United Kingdom 72.6/531
The x and y values shown above were used to determine the Correlation Coefficient (link for calculator below) between the two.
