But, we can probably reduce the number of cases per year to near 0 in the US, if all eligible people get vaccinated. Wiki told me there were under 500 confirmed cases in the US in 2018, and Google told me that r_0 for measles is between 12 and 18. COVID is nowhere near that transmissible.

I don't see that ever happening, at least for another generation or two.

There's also natural immunity for the ones who'd rather have that than the scary scientist-designed shot. The most irresponsible ones have the best chance of getting nature's vaccine. Depending on how long immunity lasts, that might drive it very low.

And as far as I know, the vaccines are highly effective and very few people are actually medically unable to get this vaccine. Honestly, if only people who chose not to be protected from it die... too bad for them.
