The first human trial of an experimental vaccine against Ebola suggests that it is safe and may help the immune system to combat the virus.

Twenty volunteers were immunised in the United States. Scientists at the US National Institutes of Health (NIH) described the results as "promising".

The research is published in the New England Journal of Medicine (NEJM).

None of those immunised suffered major side-effects and all produced antibodies.

Dr Anthony Fauci of the NIH told the 大象传媒: "On safety and on the ability to produce an appropriate immune response we can call this trial an unqualified success, even though it was an early Phase One trial."
