- Healthy Volunteers: t

Study Arms:
- Cervarix Group (Type: ACTIVE_COMPARATOR): Healthy female subjects who received 3 doses of Cervarix at Months 0, 1 and 6, administered intramuscularly into the deltoid region of the non-dominant arm. For some analyses the group was stratified by age into a 10-14 years of age group and a 15-25 years of age group.
- Placebo Group (Type: PLACEBO_COMPARATOR): Healthy female subjects who received 3 doses of placebo at Months 0, 1 and 6, administered intramuscularly into the deltoid region of the non-dominant arm. For some analyses the group was stratified by age into a 10-14 years of age group and a 15-25 years of age group.
