You can quibble over details all you want but those numbers clearly show that on average two thirds of the daily new cases and three quarters of the people in hospitals aren't protected by vaccines. Way less than half of the population - the unvaccinateded and the not-fully-vaccinated - is providing way more than half of the patients.

Using the fact that it takes a some time for the vaccines to work properly is your way of closing your eyes and putting your hands over your ears.
