An unsolicited adverse event is any adverse event (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.

Medically significant conditions were defined as: adverse events (AEs) prompting emergency room or physician visits that were not (1) related to common diseases or (2) routine visits for physical examination or vaccination, or SAEs that were not related to common diseases. Common diseases included: upper respiratory infections, sinusitis, pharyngitis, gastroenteritis, urinary tract infections, cervicovaginal yeast infections, menstrual cycle abnormalities and injury.

HPV-16 assay cut-off value was defined as greater than or equal to (≥) 8 ELISA units per millilitre (EL.U/mL) at PRE vaccination, Month 7, 12 and 24 and ≥ 19 EL.U/mL at Month 36, 48 and 72. Seronegative (Sero-) subjects are subjects who had an antibody concentration below 8 EL.U/mL prior to vaccination. Seropositive (Sero+) subjects are subjects who had an antibody concentration ≥ 8 EL.U/mL prior to vaccination.

The analysis was performed on the ATP cohort for analysis of immunogenicity, which included all evaluable subjects in the immunogenicity subset for whom data concerning immunogenicity endpoint measures were available at the specified time points.
