Medical experts say the best indicator of how effective the vaccines are is the correlation between vaccinated and unvaccinated in ICUs. In Germany the ICU ratio is 1 vaccinated/10 unvaccinated with the above-mentioned 70% of the population partially vaccinated. That is to say, German unvaccinated individuals have a risk of ending up in an ICU that is 21 times as high as their vaccinated counterparts. Vaccine uptake is lowest in the conservative and rural south and the former East Germany, the latter attributed by some to a long-lasting distrust of government going back to its days as a Soviet satellite.
