Ebola vaccine trial shows 100 percent effectiveness

A vaccine developed by Merck is the first shown to be highly effective in preventing human infection with Ebola, according to final results from a clinical trial. Among 5,837 people who received the rVSV-EBOV vaccine in the trial in Guinea in 2015, no Ebola cases were recorded 10 days or more after vaccination, signaling 100 percent protection.
