Edouard Mathieu, and Max Roser. "How do death rates from COVID-19 differ between people who are vaccinated and those who are not?". Our World in Data. (1637625600)November 23, 2021. https://ourworldindata.org/...
When headline say “Half of those who died from the virus were vaccinated”, we don't know whether or not the vaccine is protecting people. For this, we need to know how many people were vaccinated and how many were not. Comparisons of the absolute numbers is a "base rate fallacy". If 5 of 10 unvaccinated people died, the death rate among the unvaccinated is 50%. If 5 of 50 vaccinated people died, the death rate among the vaccinated is 10%. This only tells us that the death rate among the vaccinated is 5-times lower than among the unvaccinated.
