Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Solicited symptoms were collected for 3730 and 3740 subjects instead of the 3727 and 3739 subjects who were randomized in the study in the Cervarix and the Havrix groups, respectively. These 4 sujects received both vaccines and were included in the denominator of both arm based on the actual vaccine type administered.

Reporting Groups
  Description
Cervarix Group Subjects received 3 doses of Cervarix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.
Havrix Group Subjects received 3 doses of Havrix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.

Measure Type Secondary
Measure Title Number of Subjects Reporting Unsolicited Adverse Events (AEs).
Measure Description 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.
