Summary
Moffitt Cancer Center is the Coordinating Center for this study.
The purpose of this study is to develop and test the infrastructure to conduct a future Phase III vaccine efficacy trial to assess trial feasibility, and to assess human papillomavirus (HPV) genotype distribution, data needed to design a Phase III trial. The investigators propose to conduct a Preparedness study among women ages 16-24 years of age residing in a region of South Africa with a high human immunodeficiency (HIV) incidence and prevalence.
The specific aims of this study are to:
1. Identify, recruit, enroll, and randomize a cohort of HIV negative women (200 per arm, 400 total) ages 16-24 years to an HPV vaccine against 4 types (HPV 6, 11, 16, 18 [Gardasil]) or placebo vaccine.
2. Determine the cervical HPV prevalence and type distribution at enrollment, and cervical lesion prevalence among young females ages 16-24 years at high risk for HIV infection.
3. Assess the rate of compliance through the 3-dose vaccination series
Eligibility Criteria
Inclusion Criteria
- Women ages 16-24 years of age residing in a region of South Africa with a high HIV incidence and prevalence

- has never had Papanicolaou smear (Pap) testing or has only had normal Pap test results
- fully understands study procedures, risks involved in the study, and voluntarily agrees to participate by giving written informed consent
- agrees to refrain from douching/vaginal cleansing and using vaginal medications or preparations for 2 calendar days prior to the Day 1 visit as well as other future visits that include collection of cervical specimens
- agrees to refrain from sexual intercourse for 2 calendar days prior to the Day 1 visit as well as other future visits that include collection of cervical specimens
- agrees to utilize effective contraception during sexual intercourse (excluding the rhythm method, withdrawal alone, and emergency contraception) during the vaccination period.
- Informed consent procedures for females <18 years of age: Informed consent and informed assent will be obtained from parents/legal guardians and adolescents respectively, prior to participation. The consent form will include information about the study and individual request for consent of participants to participate in the study. It will be emphasized that participation is voluntary and that participants are free to withdraw from the study at any stage without any disadvantage to them. An assessment of understanding will be conducted at screening to ensure that consent is informed.
