MAEs were defined as adverse events with medically-attended visits that were not routine visits for physical examination or vaccination, such as visits for hospitalization, an emergency room visit, or an otherwise unscheduled visit to or from medical personnel (medical doctor) for any reason. Any was defined as any occurrence of MAE(s) regardless of intensity grade or relationship to vaccination. Related was defined as MAE assessed by the investigator to be causally related to the study vaccination.
Time frame: Throughout the study period (Days 0-180)
Number of Subjects Reporting the Occurrence of Potential Immune Mediated Diseases (pIMDs)
Potential immune-mediated diseases (pIMDs) were defined as a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology. Any was defined as any occurrence of pIMD(s) regardless of intensity grade or relationship to vaccination. Related was defined as pIMD assessed by the investigator to be causally related to the study vaccination.
Time frame: During the entire study period (Days 0-180)
Number of Subjects Reporting Any, Grade 3 and Related Unsolicited Adverse Events (AEs).
An unsolicited AE was defined as an 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 and 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.
Time frame: Within the 28-day (Days 0-27) post-vaccination period
Number of Subjects Reporting Serious Adverse Events (SAEs)
SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are 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: Throughout the study period (Days 0-180)
