Study to Evaluate the Immunogenicity and Safety of a Heterologous Vaccine Regimen Against Ebola

Summary

This Phase 2 study aims to improve preparedness for future Ebola outbreaks by vaccination of a well-known population at risk, ie, a cohort of health care providers (HCP) (such as primary, emergency, and community health care workers) who may be exposed to Ebola in the event of a future outbreak in the Democratic Republic of the Congo (DRC). This study will enhance the immunogenicity database by investigating the kinetics of the humoral immune response. The study will contribute to the safety database (serious adverse events) for VAC52150 following a heterologous vaccine regimen with Ad26.ZEBOV as first vaccine followed by second dose with MVA-BN-Filo administered 56 days later (Day 57). Additionally, after randomization (1:1), a booster vaccination with Ad26.ZEBOV will be executed at 1 year post first dose or 2 years post first dose.
