heres how I know; vietnam & australia didn't need the vaccine to do it, so whatever it is that caused the US to not be able to deal with the pandemic without the vaccine is also gonna make the US be unable to deal with the pandemic with the vaccine.
The lack of the vaccine isn't the problem, corruption is. It isn't a tech problem, it's a governance problem. The US is gonna have COVID for ever.
PS, the exact same thing applies for climate change. Ppl be like "oh climate change will be fixed once we invent the right tech". The thing is, we already have the tech to end climate change, we're just ruled by ppl who don't want to. We're fucked, and we're fucked forever, stop waiting for the ghost of albert einstein to solve your problems for you with a glass vial & recognize that anyone who tells you to is the enemy
It's not so simple, even if that percentage of the population doesn't get vaccinated, the rest have either contracted the virus already, will contract the virus anyways after a short period of time, or spread will just completely stop due to herd immunity combined with measures. It's hard to tell for sure what will happen but diseases have been eradicated due to vaccination in the past, it may not happen immediately but it may still happen eventually. Then again, maybe it won't happen at all, but if vaccines improve to the point where distribution isn't as hard as it's been so far (and they probably will), it won't really be an issue any more. Measles is an extremely contagious disease, far more so than covid, but it was eradicated in many countries due to vaccinations. Of course one complication is that immunity from measles lasts pretty much for a lifetime, whereas it's probably not the same for covid. But we shall see.
