Scientists worldwide are hard at work on vaccines against the virus. A recent US trial of a new vaccine looks positive, with volunteers showing a strong immune response. The vaccine is made from a genetically engineered chimpanzee cold virus.
Though this 'phase 1' trial was small, it showed the vaccine is safe - and the next step is to move ahead with a larger trial in west Africa.
