PRIMARY outcome

Timeframe: Within 1 Month After Vaccination

Population: The safety population included all participants who received any study intervention and had safety data assessed after vaccination.

An AE was any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Local reactions (redness, swelling, and pain at the injection site) and systemic events (fever, headache, fatigue, muscle pain, and joint pain) were not collected as AEs.

PRIMARY outcome

Timeframe: Within 1 Month After Vaccination

Population: The safety population included all participants who received any study intervention and had safety data assessed after vaccination.

An SAE was any untoward medical occurrence at any dose that resulted in death, was life-threatening (immediate risk of death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions), resulted in congenital anomaly/birth defect or considered to be an important medical event.

The same event may appear as both an AE and an SAE. However, what is presented are distinct events. An event may be categorized as serious in one participant and as non-serious in another participant, or one participant may have experienced both a serious and non-serious event during the study. The safety population were participants who received study intervention and had safety data assessed after vaccination.
