One third of the US population is considered at risk due to comorbidities. With over 328M people in the US, that's roughly 100M.

If you look worldwide, there are 7.8B people. If herd immunity takes 60% of the population becoming infected, that's 4.6B infections. With an IFR of 1%, that's 46.8M deaths. 460M hospitalizations (where possible).

Even say the IFR is overstated as some like. Say it's a magnitude less, comparable to the flu at .1% Now you are down to 4.7M deaths, but still the 460M hospitalizations. Still one of the most serious crises in the last 100 years.
