   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).

   Time frame: During the entire study period (Day 0 to Day 180)

   Potential immune-mediated diseases (pIMDs) were defined as a subset of adverse events that included both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which might or might not have an autoimmune aetiology. Any pIMD was defined as at least one pIMD experienced by the study subject.

Any was defined as occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination.
