here is another graphic derived from CDC weekly covid datasheets links below

this perhaps also helps to show as more folks get vaccinated, in proportion to the unvaccinated (top panel), the greater the numbers appear in the lower panel.(but the total will always be fewer than if more folks remain unvaccinated)

it's a difficult concept as more of us are now vaccinated and yet hospitalisations contain more vaccinated

here are some more useful graphics (thx SpookyHead!)

Simpson's paradox

and "absolute numbers [make] a mistake that’s known in statistics as a ‘base rate fallacy’: it ignores the fact that one group is much larger than the other" How do death rates from COVID-19 differ between people who are vaccinated and those who are not? "
