Interventions

NameTypeDescription
MV-LASVBIOLOGICALThe MV-LASV vaccine candidate is a recombinant live attenuated viral vectored vaccine, based on the backbone of the measles Schwarz virus strain for prophylaxis of Lassa infection and will be administered in two different dose levels by intra muscular (i.m.) injection.
PlaceboOTHERA sterile physiological saline solution will be used as placebo to ensure blinding of the treatment with low dose MV-LASV and placebo within treatment group A. Additionally, the Placebo will be used as a control arm to enable comparison of treatment reactions within treatment groups B and C.
