The most advanced vaccines in the US and Europe include Ervebo (rVSV-EBOV), Zabdeno/Mvabea (Ad26-ZEBOV/MVA-BN-Filo), and cAd3-EBOZ (with or without MVA-BN-Filo). These platforms use a viral vector to provoke an immune response, but, as illustrated, there are several distinctions among these 3 vaccines including vector virus, dose, efficacy, cell targets, and inclusion of a booster.
