Phial of ebola vaccine being drawn into a syringe during a trial. The trial will determine if the vaccine is safe in humans and if it induces an adequate immune response. The vaccine uses a chimpanzee cold virus (chimp adenovirus type 3) to carry the genetic material for an ebola virus protein. The viruses cause ebola virus disease (EVD), a severe and often fatal disease with symptoms including fever, fatigue, muscle aches, vomiting, diarrhoea and haemorrhaging (internal bleeding). It is spread through direct contact with infected bodily fluids. There is no cure for the disease, but three quarters of patients can recover if provided with sufficient medical support. Photographed at the University of Oxford, UK, on 14 November 2014.
