“We believe that the world is on the verge of an efficacious Ebola vaccine,” WHO vaccine expert Marie Paule Kieny told to the media in a briefing from Geneva. WHO Director-General Margaret Chan appreciated the result as an “extremely promising development.” The trial is now being continued, with all participants receiving the vaccine immediately, and will be extended to include 13- to 17-year-olds and possibly also 6- to 12-year-old children, the WHO said. This is necessary before a massive use as prevention in the most critical areas on the world. Ebola has killed more than 11,200 people in West Africa since it began in December 2013.
