Evaluation of the Safety and Immunogenicity of Three Consistency Lots and a High-Dose Lot of rVSV-ZEBOV-GP (V920 Ebola Vaccine) in Healthy Adults (V920-012)

Summary

The study evaluated the safety and immunogenicity of 3 consistency lots and a high-dose lot of rVSV-ZEBOV-GP (V920 Ebola Vaccine) in healthy adults. The primary purpose of this study was to demonstrate consistency in the immune responses of participants receiving 3 separate lots of V920 through 28 days postvaccination. In addition to the 3 lot groups, a high-dose group and a placebo group were studied. A subset of participants representative of all treatment groups continued through 24 months postvaccination in the extension study for the evaluation of long-term safety. The primary hypothesis states that the geometric mean titer of anti-Zaire ebolavirus envelope (ZEBOV) glycoprotein antibody at 28 days postvaccination is equivalent across the three consistency lots.
