The number of subjects completing the 3-dose vaccination schedule was defined as the number of subjects who received the 3 active doses (placebo administrations are not reflected).

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site. All solicited local symptoms were assessed as related to study vaccination.

Analyses were performed on subjects with available data within the Total Vaccinated cohort, which included subjects with at least one vaccine administration.

Assessed solicited general symptoms were arthralgia, fatigue, fever [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], gastrointestinal, headache, myalgia, rash and urticaria. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.

Analyses were performed on subjects with available data within the Total Vaccinated cohort, which included subjects with at least one vaccine administration.
