Studies on Covid-19 vaccine effectiveness against hospitalization/death


Most stories on vaccine effectiveness against hospitalization/death look like this:

Nearly all COVID deaths in US are now among unvaccinated - https://apnews.com/article/coronavirus-pandemic-health-941fcf43d9731c76c16e7354f5d5e187

Unvaccinated people were 11 times more likely to die of covid-19, CDC report finds - https://www.washingtonpost.com/health/2021/09/10/moderna-most-effective-covid-vaccine-studies/

CDC study shows unvaccinated people are 29 times more likely to be hospitalized with Covid - https://www.cnbc.com/2021/08/24/cdc-study-shows-unvaccinated-people-are-29-times-more-likely-to-be-hospitalized-with-covid.html

All of them refer to heavily confounded data (e.g. no medical history) and I'm having difficulties finding more thorough studies.

Are better analyses available/underway? Thank you!

Another example of "extensive unassailable and striking evidence": A death rate comparison between Romania, Bulgaria (low vax rate: 30.5% & 20%) and other EU countries (high vax rate >65%) [1].

The evidence looks "striking", but when you start to cherry pick other EU countries, the evidence becomes ambiguous [2]. Germany's vax rate is 66.2%. Poland's 52.3%. Slovakia's 42%. Yet, they all share a similar death rate.

Does that mean that there's no difference between 42% and 66.2%? Or does it mean that it's pointless to compare death rates between countries with different demographics, health care, etc..?
