Ebola crisis: Vaccine 'too late' for outbreak
UK pharmaceuticals firm GlaxoSmithKline says its Ebola vaccine will "come too late" for the current epidemic.
GSK is one of several companies trying to fast-track a vaccine to prevent the spread of Ebola in West Africa.
But Dr Ripley Ballou, head of GSK's Ebola vaccine research, said full data on its safety and efficacy would not be ready until late 2015.
