Missing mortality reduction after Covid-19 vaccination

In statistics, we have precise methods to measure the effectiveness of the Covid-19 massive vaccination. Vaccinated people should be healthier, and should have a lower death rate than non-vaccinated people. Vaccinated people should have fewer sick days than non-vaccinated people. The expected diminished death rate would be the best proof of the covid vaccination effectiveness. The efficiency of massive covid vaccination should result in a diminished death rate of the fully vaccinated group in comparison to the non-vaccinated groups of the population in a given country. Using official data from UK Health Security Agency to calculate the death rate of the vaccinated infected groups and the death rate of non-vaccinated infected groups has shown that covid-19 vaccination did not diminish the death rate.
