Fauci cautions that a Covid-19 vaccine won't eliminate the need for masks

Something about this doesn't make much sense to me. "Fauci said he's being 'practical' when he says, 'I think if we can get 75 to 80% of the population vaccinated, I think that would be a really good accomplishment.'"

If 75% of the population is vaccinated and the effectiveness is 90%, that ought to drop R0 below one pretty quick.

There seems to be a lot of "mental fatigue" with all these virus measures. Eventually, people are just going to stop complying. At some point, hitting people over the head with regulations is just going to be ineffective. It's already hitting that point even without any vaccinations at all.

Plus, with so many people surviving the virus while asymptomatic, people are going to think it is all overkill. My parents who are in their late 70's were tested positive and didn't even get a fever. They aren't wearing masks anymore, and I doubt you could force them to do so at gunpoint now.

https://wwwnc.cdc.gov/eid/article/26/7/20-0282_article estimates R₀ ≈ 5.7. If that's accurate, the vaccine would reduce the rate to ~1.9, which is still bad.
