Ad26.ZEBOV-Batch #3
Ad26.ZEBOV-Batch #3 is a Viral vector vaccine Biologic drug developed by Crucell Holland BV. It is currently in Phase 3 development for Ebola virus disease prevention.
Ad26.ZEBOV is a replication-incompetent adenovirus serotype 26 vector expressing the Ebola virus glycoprotein, designed to elicit immune responses against Ebola virus.
Ad26.ZEBOV-Batch #3 is an intervention being studied in a clinical trial for its immunogenicity, safety, and tolerability in healthy adult participants. The mechanism of Ad26.ZEBOV-Batch #3 is unknown.

Baseline phase 3 → approval rate
+58.3pp
Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas). -
Immunology slight uplift
+1.0pp
Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.

Mechanism of action
This vaccine uses a non-replicating adenoviral vector to deliver the gene encoding the Ebola virus surface glycoprotein, triggering both cellular and humoral immune responses. The Ad26 vector is engineered to be safe and immunogenic while the expressed glycoprotein serves as the antigen target. This approach is part of a heterologous prime-boost vaccination strategy, often paired with MVA-EBOV as a booster dose.
