Exerpts:

Government scientists have developed a new vaccine against the dread Ebola virus that works rapidly after a single injection, an unexpected success that means the nation could soon have a defense against one of the most fearsome weapons in the terrorist arsenal.

...

To everyone's surprise, it worked remarkably well. Some monkeys got a single injection of the test vaccine, and some got a fake injection. A month later, they were deliberately infected with Ebola. Those that got the placebo died the usual horrible death, and the ones that got the vaccine didn't get sick at all.

...

"Lo and behold, the results really exceeded our expectations," said Gary J. Nabel, leader of the NIH vaccine center and principal author of the new Nature paper. "The idea that you could give a single shot and within a month get 100 percent protection, that's clearly encouraging."

...

Some unknown proportion of the population already has natural immunity to adenovirus that could be strong enough to prevent the vaccine from working. Scientists are thinking up ways around that problem, but even if they succeed, a given person might be able to receive an adenovirus vaccine only once, because that first shot would create an immune response that might prevent subsequent adenovirus vaccines from working.

...

Scientists said the situation could prompt a debate within the government about which adenovirus vaccine should receive the highest priority, or whether to try to create a combination adenovirus vaccine to protect against multiple terrorist agents.

Wow. Interesting. I do hope, though that they continue to explore all the angles (form the adenovirus POV) before utilizing it in a wdiespread mannr on the African continent.
