Ebola vaccine trial. Man receiving a dose of the investigational NIAID/GSK ebola vaccine. This 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 segments of genetic material from two ebola viruses. 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 NIH Clinical Center, Bethesda, Maryland, USA, on 4th September 2014.
