Summary
Ebola virus has infected and killed people, mostly in Africa. In 2014, the Ebola virus has affected several thousand people. There is no approved effective way to treat or prevent Ebola. Researchers are trying to develop a vaccine for it. This is a study of the anti-Ebola vaccine BPSC-1001 to see if it is safe and to see how it affects people's immune system.
