Number of Subjects Reporting Any Unsolicited Adverse Events (AEs).Secondary· During the 21-day (Days 0-20) post-vaccination period.
An unsolicited AE was defined as any AE (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination.

A serious adverse event was any untoward medical occurrence that resulted in death, was life threatening, required hospitalization or prolongation of hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination and related was an event assessed by the investigator as causally related to the study vaccination.

Time frame: Serious Adverse Events: During the entire study period (Days 0 - 20 after vaccination); Solicited local and general symptoms: During the 4-day (Days 0-3) post-vaccination period; Unsolicited symptoms: During the 21-day (Days 0-20) post-vaccination period..
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of this study is to evaluate the immunogenicity and the safety of GlaxoSmithKline (GSK) Biologicals' investigational quadrivalent split virion influenza vaccine FLU-Q-QIV in adults 18 years of age and older.
