Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* Study participants who the investigator or delegate believes that they and/or their parents/legally acceptable representative can and will comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits) should be enrolled in the study.~* A male or female between, and including, 12 and 15 years of age at the time of the first vaccination.~A written informed assent must be obtained from all study participants prior to enrolment. In addition, a written informed consent must be obtained from the study participants' parent or legally acceptable representative.~Note: As according to the Finnish law legal age of consent is 15 years, a written informed consent form can be obtained from study participants aged 15 years old and their parent(s)/legally acceptable representative(s) will receive a letter informing them of their child participation to the study.~* Healthy male and female study participants as established by medical history before entering into the study. If needed, a history-directed clinical examination will be performed by the investigator or delegate (e.g. study nurse).~* Study participants must not be pregnant. Absence of pregnancy should be verified (e.g. urine pregnancy test) as per investigator's or delegate's clinical judgement.~* If the study participant is female, she must be of non-childbearing potential, i.e. be abstinent, have a current tubal ligation, hysterectomy, ovariectomy or be post-menopausal or pre-menarcheal, or if she is of childbearing potential, she must use adequate contraception for 30 days prior to vaccination and continue for 2 months after completion of the vaccination series.~Exclusion Criteria:~* Previous vaccination against HPV or Hepatitis B virus.~* History of allergic disease or reactions likely to be exacerbated by any component of the vaccines.~* Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhoea, mild upper respiratory infection with or without low-grade febrile illness, i.e. Oral temperature \<37.5°C (99.5°F) / Axillary temperature \<37.5°C (99.5°F) / Rectal temperature \<38°C (100.4°F).)~* Pregnant or lactating female.

Study Arms:
- Cervarix/Engerix-B A Group (Type: EXPERIMENTAL): The A group includes subjects from communities where 70% of male and female adolescents were to be vaccinated with Cervarix vaccine. To achieve a Cervarix vaccination coverage of 70%, a 9:1 ratio was used to allocate study participants to receive Cervarix vaccine versus control Engerix-B vaccine (meaning 90% of vaccinated subjects were randomized to Cervarix). Finally, subjects from A group were either vaccinated with Cervarix, Engerix-B (control vaccine), or not vaccinated (enrolled control without vaccination). Vaccines were administered intramuscularly in the deltoid region of the non-dominant arm according to a 0, 1, 6-month schedule.
- Cervarix/Engerix-B B Group (Type: EXPERIMENTAL): The B group includes subjects from communities where 70% of female adolescents were to be vaccinated with Cervarix vaccine. To achieve a Cervarix vaccination coverage of 70%, a 9:1 ratio was used to allocate female participants to receive Cervarix vaccine versus control Engerix-B vaccine (meaning 90% of vaccinated females were randomized to Cervarix). In this group, all male adolescents were to be vaccinated with Engerix-B control vaccine. Finally, subjects from B group were either vaccinated with Cervarix (females) or Engerix-B/not vaccinated (males and females). Vaccines were administered intramuscularly in the deltoid region of the non-dominant arm according to a 0, 1, 6-month schedule.
- Engerix-B Group (Type: ACTIVE_COMPARATOR): In this control group, all adolescents were to be vaccinated with Engerix-B control vaccine. Finally, subjects from this group were either vaccinated with Engerix-B or not vaccinated. The vaccine was administered intramuscularly in the deltoid region of the non-dominant arm according to a 0, 1, 6-month schedule.
