Vaccination does reduce the proportion of people that need ICU beds, but there are pretty rapid diminishing returns on just vaccinating more; countries have reached the point where the majority of Covid patients in their ICUs are vaccinated at well below 100% vaccination. Also, vaccinating younger lower-risk people doesn't help because they're at substantially lower risk of needing the ICU even unvaccinated than someone older or higher-risk who is vaccinated and because the vaccines aren't really useful to stop the spread of the disease either. Countries have generally had significantly higher vaccine acceptance amongst older people who need it more. (Though I think one of the big problems Germany has is their vaccine uptake amongst the elderly is somewhat low compared to other countries.)
