An immunization regimen using two Ebola vaccine candidates was safe and well-tolerated and induced an immune response in healthy adult volunteers in a Phase 1 clinical trial. Results from the study are described in the April 19th issue of the Journal of the American Medical Association. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), has supported the development and testing of the two investigational vaccines: Ad26.ZEBOV, developed by Crucell Holland B.V., and MVA-BN-Filo, developed by Bavarian Nordic.
