“It took a major Ebola epidemic that led to more than 11,000 deaths, but we now finally have a successful Ebola vaccine candidate in development. If approved, the vaccine would vastly reduce the likelihood of ever seeing another major Ebola outbreak.

They showed that everyone who got the shot immediately after contact with an Ebola victim didn’t get the virus.”
