Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part A: Number of Participants With Any Solicited Adverse Events (AEs) (Local and Systemic Reactogenicity Events)	Solicited AEs, including local and systemic AEs were recorded by participants daily using the memory aid. Solicited local AEs include injection site induration/swelling, injection site tenderness, injection site erythema/redness, and injection site pain. Solicited systemic AEs include body temperature (oral), generalized myalgia (muscle ache or pain), generalized arthralgia (joint ache or pain), headache, fatigue/malaise (unusual tiredness), nausea/vomiting, and diarrhea. A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.	7 days following each vaccination
Primary	Part A: Number of Participants With Unsolicited AEs	An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A treatment-emergent AE (TEAE) was defined as any event not present before exposure to vaccine or any event already present that worsens in intensity or frequency after exposure. A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.	28 days following each vaccination
Primary	Part A: Number of Participants With Serious AEs (SAEs), Medically-Attended AEs, and AEs of Special Interest	An MAAE is an AE that leads to an unscheduled visit to a healthcare practitioner (HCP). An SAE was defined as any AE that resulted in death, is life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/permanent damage, was a congenital anomaly/birth defect, or was an important medical event. AEs of special interest were evaluated as defined in the protocol. A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.	28 days following each vaccination
Primary	Part B: Number of Participants With SAEs and AEs of Special Interest	An SAE was defined as any AE that resulted in death, is life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/permanent damage, was a congenital anomaly/birth defect, or was an important medical event. AEs of special interest were evaluated as defined in the protocol. A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.	Through 1 year following the last vaccination
