Researchers say they're a step closer to developing an Ebola vaccine, with a Phase 1 trial showing promising results, but it will be months at the earliest before it can be used in the field. The news comes amid the worst ever outbreak of the hemorrhagic fever, which has killed nearly 5,700 people, mostly in West Africa.
