Eligibility Criteria

Age4 Years - 26 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsParticipant is of female sex (based on participant/parent self-report)
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Signed/thumb-printed informed consent obtained from the participant's parent (4 to 17 year-olds) or signed/thumb-printed informed consent obtained from the participant (18 years and above)
  • Signed/thumb-printed assent obtained from the participant (12 to 17 year-olds only).
  • Documented verbal assent obtained from the participant (6 to 11 year-olds only)
  • Participant is of female sex (based on participant/parent self-report)
  • Participant is between 4 and 26 years of age inclusive
  • Parent/participant is willing and judged able to comply with the necessary study procedures
  • Parent/participant does not have established plans to leave the study area for a prolonged period/indefinitely during the 3 year follow-up period
  • Participant is resident within the study area (no fixed boundaries will be set and decisions will be made on a case-by-case basis by the study team taking into account not only distance but also transport links, accessibility for the purposes of safety data collection, willingness of the parent/participant to travel)
  • Place of residence of the participant must be readily identifiable

You may not qualify if:

  • Receipt of other investigational medicinal products (IMP) in a period of 12 months prior to the day of randomization and vaccination or plans to receive IMP during the trial.
  • Presence of significant chronic health problems requiring long-term medication or medical follow-up including respiratory, cardiac, gastrointestinal, hepatic, renal, neurological, musculoskeletal, haematological or other conditions based on parental history and physical examination of the participant. Participants with known sickle cell disease (but not sickle cell trait) will be excluded.
  • Prior receipt of an HPV vaccine
  • Receipt of any vaccine in the 28 days prior to randomization and vaccination‡
  • History of thrombocytopenia or coagulation disorders which represent contraindications in intramuscular (IM) vaccination
  • Known congenital or acquired immune deficiency or history strongly indicative of abnormal immune function. HIV testing will not be undertaken as part of the routine screening procedures due to the relatively low prevalence of HIV expected in the population (\~1-3%) and the established safety and immunogenicity profile of Gardasil in HIV positive individuals.
  • Receipt of intravenous immunoglobulins or blood products within a period of 12 months prior to the day of randomization and vaccination or plans to receive such products during the course of the trial.
  • Intention to become pregnant within six months of enrollment in the trial. Confirmation regarding the use of a reliable method of contraception is not required but females who are actively seeking to become pregnant within six months of enrollment will be excluded.
  • Fever (\>38.0°C) on the day of vaccination or documented fever (\>38.0°C) within the 24 hours preceding vaccination
  • Abnormal (Grade \> 1) vital signs (heart rate, respiratory rate, blood pressure) on the day of vaccination
  • Positive rapid diagnostic test (RDT) or blood film for malaria on the day of vaccination
