Summary

The goal of this randomized controlled trial is to investigate whether individuals in DRC previously vaccinated with Zabdeno/Mvabea® or Ervebo® vaccine schedules against Ebola virus can be safely and adequately boosted with homologous or heterologous vaccine schedules. Participants will be randomized to receive either a homologous or heterologous vaccine schedule and will be asked to come to the clinic at prespecified timepoints over a period of 6 months to collect blood samples for comparison of immunological responses against Ebola virus between both schedules. Safety and tolerability of the vaccines will be evaluated by recording Adverse Events (AE's) and grading physical and vital signs evaluations.
