The first batch of GlaxoSmithKline's experimental Ebola vaccine has been dispatched to West Africa and is expected to arrive in Liberia later on Friday, the British drugmaker said.
The World Health Organization said on Thursday the Ebola outbreak in West Africa, the worst in history, appears to be waning but cautioned against complacency. The epidemic has seen 21,724 cases reported in nine countries since it started in Guinea a year ago. Some 8,641 people have died.
