My gut feeling is that it would take strong and probably obnoxious enforcement to get us to one 9, we probably can’t even get two 9s (as in 99%, since some people think that means 99.99%) due to the number of people medically ineligible. And all that’s after approving any vaccine for kids, which we haven’t done yet.

I mean you think that 30+ million people in the US will be medically ineligible? Every single vaccine in my state is being administered as fast as they can ship them out. And after a while kids will have to be vaccinated to go to school same as we do with other vaccines. There is no current prediction that the vaccine won't be safe for kids.

The biggest groups that are ineligible are people with vaccine allergies and people with some autoimmune diseases which is vanishingly small.
