'Positive signs' from Ebola vaccine trial

The first human trial of an experimental Ebola vaccine suggests it is safe and it may well protect people from the deadly virus.

Twenty volunteers received the jab in the United States with no major side effects.

The results of the independent trials have just been reported in the New England Journal of Medicine, but the head of the pharmaceutical giant GSK has told the BBC that companies manufacturing the vaccine should not have to shoulder all the financial risk.
