The purpose of this study is to provide the needed safety and immunogenicity data to support rapid deployment of the SEBOV vaccine against an ongoing or future outbreak.~The intervention will be a single dose and will either be study vaccine named rVSVΔG-SEBOV-GP Vaccine, or placebo (a placebo is an inactive substance or other intervention that looks the same as and is given the same way as study vaccine or treatment being tested)~There are 3 group in this study, each group has different vaccine doses. Group 1 starts with the lowest dose of the study vaccine and each subsequent group Groups 2 and Group 3 gets a higher dose of the study vaccine.~Approximately 36 participants will be included in the study.~The participant will be unaware of the treatment given between placebo and study vaccine.~Participants will be screened up to 14 days before IP administration and will be followed for 6 months after IP administration. The anticipated study duration for each participant in Groups 1 through 3 is approximately 6.5 months from screening through last study visit.
A Phase 1, Single-blind, Placebo-controlled, Dose-escalation Clinical Trial to Evaluate the Safety and Immunogenicity of rVSVΔG-SEBOV-GP Vaccine at 3 Dose Levels in Adults in Good General Health
