Given the size of the trial, it's really unlikely that it prevents less than 90% of the cases of Ebola that would otherwise develop. So while I agree that 100% continuing is all that likely, especially if you start including immune suppressed people such as the HIV positive, those with cancer, transplants, young children, the elderly, etc... Still, if you vaccinate 100% of those eligible for it and it provides 95% immunity to Ebola, odds are the vulnerable won't be exposed at all, because you'll have something like 5% of the flare-ups from a wild source, and such flareups should mostly be individual, not thousands.
On the other hand, thinking about Ebola and vaccines reminded me that vaccines have made an even deadlier disease less problematic - Rabies. It wasn't until a relatively short time ago that we had any survivors from the symptomatic stage, and even then getting those requires putting them into a medical coma for a while.
But with the vaccine we realistically save thousands of human lives every year in the USA alone, and that's with mostly vaccinating animals, not people, and only vaccinating humans who we suspect have been exposed or work in a higher exposure risk area.
