  • Subjects who completed their primary vaccination and received either two or three doses of GSK Biologicals' HPV-16/18 vaccine according to a 0,6-months schedule or a 0,1,6-months schedule in the study HPV-048 PRI (110659) (NCT00541970).
  • A female between, and including, 9 and 14 years of age or 15 and 25 years of age, at the time of first vaccination, depending on which group they belonged to in the study HPV-048 PRI (110659) (NCT00541970), i.e., 9-14 year old subjects should have received two doses of GSK Biologicals' HPV-16/18 vaccine according to a 0,6-months schedule and 15-25 year old subjects should have received three doses of GSK Biologicals' HPV-16/18 vaccine according to a 0,1,6-months schedule.
  • Written informed consent obtained from the subject/from the parent(s)/LAR(s) of the subject. In addition, subjects below the legal age of consent should sign and personally date a written informed assent form.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.
Exclusion Criteria
  • Child in care.
  • Use of any investigational or non-registered product (drug or vaccine) other than the HPV-16/18 study vaccine administered in the study HPV-048 PRI (110659) (NCT00541970) from the last visit of the primary study up to the current study visit or planned use during the study period.
  • Administration of any HPV vaccine from the last visit of the primary study up to the current study visit or planned use during the study period.
  • Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within three months prior to blood sampling. Inhaled and topical steroids are allowed.
  • Planned administration/administration of a vaccine not foreseen by the study protocol within the period starting 30 days before study entry, with the exception of routine meningococcal, inactivated influenza, hepatitis B, diphtheria/tetanus and/or diphtheria/tetanus-containing, poliomyelitis and/or pertussis vaccines up to 8 days before study entry. Enrolment will be deferred until the subject is outside of specified window.
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
  • Cancer or autoimmune disease under treatment.
