Ebolavirus Zaire Vaccine
“A Trial to Evaluate the Safety and Systems Biology Response of Ebolavirus Zaire Vaccine (ChAd3-EBO-Z)”
This initial, proof of concept study will focus on identifying significant differences in response to the Ebolavirus Zaire vaccine (ChAd3-EBO-Z) when administered with placebo, MVA-BN(R)-Filo, or ChAd3-EBO-Z boosters after 8 days. All 60 participants will receive the ChAd3-EBO-Z vaccine and then randomized into each booster group (20 receiving each type of booster). Subjects will be followed-up for 6 months to monitor for safety outcomes and efficacy measures. There is no formal hypothesis for this study. The primary objective of this study is to assess the safety and reactogenicity of study products by study group when administered IM to healthy adults.
Biological - ChAd3-EBO-Z
Zaire ebolavirus vaccine administered by an IM injection into the deltoid as a single dose of 2 x 10^11 virus particles (vp)).
Biological - MVA Multi-Filo Ebola Vaccine
A booster vaccination of replication defective MVA-BN-Filo administered by an IM injection into the deltoid as a single dose of 1 x 10^8 Infectious Units (IU).
0.5 mL normal saline administered via IM injection into the deltoid.
