The purpose of this study is to demonstrate the non-inferiority of a heterologous prime-boost regimen using Ad26.ZEBOV as prime and MVA-BN-Filo as boost administered at different doses at a 56-day interval versus the same regimen with the recently released batches of Ad26.ZEBOV and MVA-BN-Filo in terms of humoral immune response against the Ebola virus (EBOV) GP (glycoprotein) as measured by enzyme-linked immunosorbent assay (ELISA) at 21 days post boost.
