Study Arms:
- Group 1: AD26.Filo/MVA-BN-Filo or Placebo (Type: EXPERIMENTAL): Participants will receive Ad26.Filo or placebo on Day 1 followed by MVA-BN-Filo or placebo on Day 57.
- Group 2: MVA-BN-Filo/AD26.Filo or Placebo (Type: EXPERIMENTAL): Participants will receive MVA-BN-Filo or placebo on Day 1 followed by Ad26.Filo or placebo on Day 57.
- Group 3: MVA-BN-Filo/AD26.Filo or Placebo (Type: EXPERIMENTAL): Participants will receive MVA-BN-Filo or placebo on Day 1 followed by Ad26.Filo or placebo on Day 15.
- Subset of Group 3: AD26.Filo or Placebo (Type: EXPERIMENTAL): The first 8 participants in Group 3 who are willing to enroll in the subset for third vaccination, will receive a third vaccination at Day 92. Participants who previously received placebo will receive placebo a third time and participants who previously received MVA-BN-Filo/Ad26.Filo vaccination will receive Ad26.Filo as third vaccination. After enrollment of the 8 participants, the unblinded monitor and unblinded pharmacist will assess whether 7 participants who previously received MVA-BN-Filo/Ad26.Filo vaccination have been enrolled. If less than 7 participants of the active vaccine regimen have been enrolled, 2 additional participants will be enrolled. If at least 7 participants of the active vaccine regimen have been enrolled, no further will be enrolled. The aim is to enroll 7 or 8 participants who will receive Ad26.Filo as third vaccination.
- Group 4: Ad26.ZEBOV/MVA-BN-Filo or placebo (Type: EXPERIMENTAL): Participants will receive Ad26.ZEBOV or placebo on Day 1 followed by MVA-BN-Filo or placebo on Day 57.

Based on this trial design, predict the completion outcome and termination type (if applicable).
