Number of Subjects With Solicited Local Adverse Events Primary · During the 7-Day (Days 0-6) post-vaccination period

Assessed solicited local adverse events were pain, redness and swelling. Any = occurrence of any solicited local adverse event regardless of their intensity grade. Grade 3 Pain = significant pain at rest. Prevented normal every day activities. Grade 3 Redness/Swelling = redness/swelling spreading beyond 100 millimeters (mm) from injection site.

Number of Subjects With Solicited General Adverse Events Primary · During the 7-Day (Days 0-6) post-vaccination period

Assessed solicited general adverse events were fatigue, fever \[defined as axillary temperature higher than or equal to (≥) 37.5 degrees Celsius (°C)\], gastrointestinal (gastro) adverse events \[nausea, vomiting, diarrhoea and/or abdominal pain\] and headache. Any = occurrence of any general adverse events regardless of intensity grade or relationship to vaccination. Grade 3 fatigue, gastrointestinal symptoms and headache = adverse event that prevented normal activities. Grade 3 fever = fever ≥ 39.5 °C. Related = adverse event assessed by the investigator as related to the vaccination.

Number of Subjects With Unsolicited Adverse Events (AEs) Primary · During the 30-Day (Days 0-29) post-vaccination period

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset out-side the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

Sponsor's own description

The purpose of this study is to assess the safety and immunogenicity of the investigational ChAd3-EBO-Z vaccine administered to approximately 3 000 adults in Africa as a single IM dose Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all subjects in the study will receive the investigational ChAd3-EBO-Z vaccine. The subjects in the Group EBO-Z will receive the vaccine at Day 0 of the study, whereas the subjects in the Group Placebo/ EBO-Z will receive a placebo at Day 0 (as a control) and will receive the investigational ChAd3-EBO-Z vaccine at Month 6, provided that no safety concerns are raised. In addition, vaccinating all subjects in the study with the investigational ChAd3 EBO Z vaccine will allow an increase of the safety database of the investigational vaccine. In case the geographic range of Ebola virus Zaire (EBOV) transmission expands to encompass any of the regions where this trial is conducted, earlier administration of the investigational ChAd3-EBO-Z vaccine to the subjects in the Group Placebo/ EBO-Z will be considered in that region.
