Two experimental Ebola vaccines pass safety test in African trial

The two vaccines, each given in a single injection, are being tested for safety and efficacy on more than 600 people in Liberia in a mid-stage clinical trial sponsored by the National Institute of Allergy and Infectious Diseases, a branch of NIH.

The Ebola epidemic that began in West Africa one year ago has killed more than 10,200 people, but a decline in new cases in the most affected countries, Liberia, Guinea and Sierra Leone, has led to hopes that it may be ending.
