1 January 2017 - Scientists battling the deadly Ebola virus are poised for a breakthrough in the new year after an experimental vaccine shot proved to be 100-percent effective during a trial in West Africa and received fast-track status from the FDA.
Among the 5,800-plus people who received the vaccine in 2015 in Guinea — one of three countries devastated by the epidemic that was only fully contained in 2016 — not one of them caught the disease 10 or more days after vaccination.
Yet there were 23 cases of Ebola among those who participated in the study but did not get vaccinated, according to newly published results in The Lancet.
