To extinguish the Ebola outbreak in the Democratic Republic of the Congo — where it has sickened at least 46 people, killed 26 and has spread to the provincial capital of Mbandaka — the World Health Organization says it's turning to an experimental vaccine.

The big picture: If it proves successful in halting this outbreak, the vaccine deployment could bring doctors and regulators closer to having an approved Ebola vaccine within the next few years.
