If 100% of the population was vaccinated, 100% of the hospitalization and deaths would be of vaccinated people. Can you see how your argument is so very stupid?
Edit: post limited, so I’m going to dump this here and not further engage in refuting such inane idiocy:
> Full dose vaccination reduced the need for ICU admission by 49.7% (95% CI = 17-70) and mortality by 56.5% (95% CI = 20-77).

EVERY study shows that vaccination is extremely effective in reducing hospitalization and mortality.
