Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
\- National Cancer Institute Protocol 04-C-N191, also known as the Costa Rica Vaccine Trial, was a double-blind controlled study of the effectiveness of an experimental human papillomavirus (HPV) vaccine in preventing cervical cancer in young women in Costa Rica. Costa Rica was part of the first large study to show the association between HPV and cervical cancer, and the study contributed greatly to the understanding of this association. The women who have participated in the vaccine trial in Costa Rica are reaching the end of the follow-up period offered in the vaccine trial protocol, and as a result they are being offered the chance to have complementary vaccinations against HPV, hepatitis A, and hepatitis B.
Objectives:
* To offer participants in the Costa Rica Vaccine Trial the vaccine that they did not receive during the masked portion of the trial (HPV vaccine or hepatitis A vaccine) and hepatitis B vaccination.
* To collect information about exposure to known and suspected risk factors for HPV infection and cervical cancer from women who are receiving vaccination against HPV at crossover.
Eligibility:
\- Women who participated in National Cancer Institute Protocol 04-C-N191.
Design:
* All participants will be offered vaccination against hepatitis B.
* Women who received the hepatitis A vaccine during the trial will be offered vaccination against HPV.
* Women who received the HPV vaccine during the trial will be offered vaccination against hepatitis A.
* Appropriate vaccinations (including a combined hepatitis A and hepatitis B vaccine) will be available to reduce the number of injections that participants will be asked to receive.
* All vaccines will be given according to the manufacturer's specifications for appropriate length of time between vaccine doses.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The profound knowledge of the natural history of HPV infection and cervical neoplasia in Guanacaste, Costa Rica together with the promising results of the different HPV vaccine trials led the National Cancer Institute, in collaboration with investigators in Costa Rica, to launch a community-based randomized phase III clinical trial to evaluate the efficacy of a virus-like particle HPV vaccine (henceforth referred to as the Costa Rica Vaccine Trial (CVT)).
The main objectives of the Costa Rica Vaccine Trial were to evaluate the efficacy of the candidate vaccine to prevent persisting HPV-16/18 infections and related histopathologically confirmed CIN2+ lesions among the according to protocol subcohort and the overall population enrolled in the study. In contrast, the objectives of this protocol are aimed at offering beneficial complementary vaccination to women enrolled in the trial with an additional objective to collect biological specimens from women receiving the HPV-16/18 vaccine to complement the information obtained during the masked phase of the trial. As an additional objective, we propose to collect information regarding exposure to known and suspected risk factors for HPV infection and cervical cancer and biological specimens during this crossover phase that will complement those collected during the masked phase of the Costa Rica Vaccine Trial.
Collection of risk factor information and biological specimens during this crossover phase will be restricted to women receiving vaccination against HPV 16/18 at crossover. These samples will permit a more complete and comprehensive evaluation of the vaccine immunogenicity. Also, those specimens will allow for ancillary analyses and studies (e.g., natural history of HPV infection acquisition/clearance) and to assist ongoing efforts to evaluate the longer-term impact of HPV-16/18 vaccination.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Planned Residence: Residents of Guanacaste or Puntarenas Province or willingness to visit one of the study clinics for participation.
* Consent: Written informed consent obtained prior to enrollment into the crossover protocol.
Exclusion Criteria
* History of (a) allergic reaction (e.g., difficulty breathing) after receipt of any vaccine, (b) hypersensitivity to latex.
* History of vaccine related adverse events during the vaccination phase that, at the discretion of the investigators, preclude vaccination during the crossover phase.
* Are receiving vaccination with Cervarix , are sexually experienced and of childbearing potential (i.e., not surgically sterilized), and are unwilling to use an effective method of birth control for 30 days before vaccination until 60 days after the last Cervarix vaccination (approximately 9 months). Acceptable forms of birth control include abstinence, surgical sterilization, hormonal contraceptives (e.g., oral, injectable, implant, and patch), intrauterine devices, and diaphragm or condom.
* History of chronic condition that per attending doctor opinion precludes her from receiving vaccination (e.g., no proper treatment available or participant is unwilling to stay under proper treatment).
* The participant has a diagnosed autoimmune illness (per the specific requirement of the INCIENSA IRB).
* The vaccine or vaccines the participant is interested in receiving are contraindicated in her case.
