Convincing a third of a billion civilians to take an unproven vaccine is orders of magnitude more difficult.

But it was an epidemic that involved immunizing only 300,000 people, and even so it took two years. And another epidemic of Ebola has already broken out on the other side of the country. And - despite the problems they had with vaccine acceptance, people are a lot more willing to be vaccinated against something with a 50% mortality than they are against something with a 0.5% (or less for the young) mortality.
I’m not against immunizations and certainly hope that we come up with an effective, safe, and cheap vaccine. But I don’t think it will be the panacea everyone seems to assume it will be.
Public acceptance and the sheer logistics of any mass immunization process are serious issues that will need to be overcome, even with a perfect vaccine.

Logistics can be solved, we have people for that... and it's already being done. They're not waiting for vaccine approval. Best vs. worst case logistics probably changes the timeline by 6-12 months. Remember, there has never before in history been this much motivation, technology, and money thrown at a medical problem.
Remember, with ebola few people actually cared that much about it, it's an isolated problem that's been proven time and again to be self-limiting in the developed world. Similar with SARS, they actually developed a vaccine but then put it on the shelf and didn't test/certify it because it wasn't worth the cost given the relatively tiny number of actual cases.

Decades-long political/social unrest doesn't have anything to do with the clinical efficacy of a vaccine.
I would agree that attempting 327M+ vaccines in the US would be a monumental undertaking facing a substantial amount of refusal. While that's a very real obstacle, SARS-CoV-2's IFR is orders of magnitude lower than Ebola Zaire and this ain't the virus from Contagion.
An approved SARS-CoV-2 vaccine would most likely first be deployed to medical professionals and first responders, then various critical essential infrastructure employees, then demographics at high risk of poor outcomes, then everybody else who hasn't already tested positive with possible ring vaccination around confirmed positive cases mixed in there.
And yeah some people would refuse, and that'd be their prerogative...but we're not eliminating this thing like smallpox in one or two or even ten years anyway.

Unless, of course, it simply burns itself out like the Spanish Flu did after a couple of years and 13 years before the first primitive flu vaccine was even developed. It is after all a NOVEL human pathogen and we simply don’t know for sure what it’s natural course may be.

A couple of teenagers with no more resources than the backseat of a parked car can produce a viable human life in nine months, maybe even twins or triplets, but that doesn’t mean that nine pairs of teenagers in the backseats of nine parked cars can produce a viable human life in a month.
The math may work but the biology doesn’t.

I am not unaware of the resources being thrown at the problem, but this is biology and queuing theory - not chemistry - and many aspects are simply not amenable to the law of mass action.

It is not all about the mortality. It is about preventing injury from the disease and it’s about reducing the number of people needing fifteen nights average in the hospital. Yes COVID is gonna circulate but if a vaccine makes it truly just the flu then we have solved a whole lot of problems with it.

Given the well-known challenges, long development periods, pitfalls, and wildly variable results of a new vaccine, wouldn’t those billions be better spent on developing promising treatments that could turn a positive case into nothing more than a garden-variety cold?
