• ‘adverse reaction’ (AR)
• Solicited injection site reaction: any AR associated with the site of injection that is pre-listed in the protocol (pain, erythema, swelling)
• Solicited systemic reaction: any AR not associated with the site of injection that is pre-listed in the protocol (fever, headache, malaise, myalgia, asthenia)
• Unsolicited AE: any observed AE that is not a solicited injection site or solicited systemic reaction
• Unsolicited AR: any unsolicited AE that is considered to be vaccine-related
SAE: any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event
