Serum was collected for determination of geometric mean titer (GMT) of anti-Zaire ebolavirus envelope (ZEBOV) glycoprotein antibodies using an enzyme-linked immunosorbent assay (GP-ELISA). The unit of measure is ELISA units/mL (EU/mL). The lower limit of quantification for the assay was 36.11 EU/mL.

An adverse event (AE) is defined as any untoward medical occurrence in a participant which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the study vaccine or protocol-specified procedure is also an adverse event. A serious AE (SAE) is an AE that results in death, is life threatening, results in persistent or significant disability or incapacity, results in or prolongs a hospitalization, is a congenital anomaly or birth defect, is any other important medical event, is a cancer, or is associated with an overdose.

Injection-site AEs prompted on the Vaccination Report Card (VRC) were erythema, pain, and swelling.

Participants were instructed on the VRC to take and record their oral (or oral equivalent) temperature daily from the day of vaccination through Day 42. Elevated temperature was defined as ≥38.0° C (≥100.4° F).

Rash AEs prompted on the VRC were petechial rash, purpuric rash, and vesicular-type rash.
