Inclusion criteria

* Young women age 16 years and 0 days to 23 years and 364 days * HIV-infection after the age of 9 years as documented by a positive result on any of the following licensed tests: any antibody test confirmed by Western blot, HIV-1 culture, HIV-1 DNA polymerase chain reaction (PCR), or plasma HIV-1 RNA \> 1,000 copies/ml * HIV treatment history that falls in one of the following categories: Group A: ART naïve or if ART-exposed, has not received HAART for at least the six months prior to study entry Group B: Has been receiving HAART for at least six months at the time of study entry, with two HIV-1 RNA plasma viral loads \< 400 copies/ml on two previous clinical visits within the 6 months prior to study entry * Willingness to avoid pregnancy from study entry through the Week 28 visit for subjects of child-bearing potential, i.e., use of at least one barrier or hormonal method; e.g., condoms, Depo-Provera, oral contraceptive pills, etc. Subjects on antiretroviral (ARV) medications must use a barrier contraceptive method because ARV medications can make hormonal birth control less effective. * Anticipated ability and willingness to complete all study vaccines and evaluations * Ability and willingness to participate in the study by providing written informed consent

Percentage of Participants Who Reported a Lower Need to Practice Safe Sex Following HPV Vaccination and the Percentage of Participants That Reported a Higher Need to Practice Safe Sex Following HPV VaccinationWeek 48Participants' perceptions for the need to practice safe sex following HPV vaccination was measured using a safer sexual behaviors subscale, which was comprised of the following five questions: After getting vaccinated against HPV … 1. You feel that condom use during sex is less necessary. 2. You feel it is still just as important to have as few sexual partners as possible. 3. You feel that it is less important to talk to your sex partners about safe sex. 4. You think it is still just as important to use a condom every time you have sex. 5. You will be less worried about having unprotected sex. Those who were categorized in the lower need for safer sexual behaviors (NSSB) group had a summary score that was less than the median and those in the higher NSSB group had a summary score that was equal to or higher than the median.
Need for Safer Sexual Behaviors (NSSB) (Evaluated by Using the 12-item Knowledge About HPV and HPV Vaccine Measure)Week 48To characterize young women's risk perceptions, sexual behaviors, and sexually transmitted infections (STI) diagnoses over the 48 weeks after initial vaccination, the relationship of baseline 12-item Knowledge About HPV and HPV Vaccine measure was used to evaluate the need for safer sexual behaviors.
Visit Compliance Via the Telephone Response System (TRS) Versus the Vaccine Report Card.Day 1 through Week 24Visit compliance is the total number of days participants actually called the TRS or completed the VRC divided by the total number of days expected to call the TRS or complete the VRC, multiplied by 100%.
Adverse Events (AE) Reported Among Participants Who Were Randomized to the Telephone Response System (TRS) or Vaccine Report Card (VRC).Day 1 through Week 24Rate of AEs is the total number of AEs divided by the total number of participants.

Need for Safer Sexual Behaviors (NSSB) (Evaluated by Using the 12-item Knowledge About HPV and HPV Vaccine Measure)

To characterize young women's risk perceptions, sexual behaviors, and sexually transmitted infections (STI) diagnoses over the 48 weeks after initial vaccination, the relationship of baseline 12-item Knowledge About HPV and HPV Vaccine measure was used to evaluate the need for safer sexual behaviors.

Number of Participants With At Least One Adverse Event Possibly, Probably, or Definitely Related to Vaccine

When a subject had at least one adverse event or sign/symptom during the study after doses 1, 2 or 3, and the event was possibly, probably, or definitely related to vaccine, this subject was considered to have had a vaccine-associated adverse event, sign and/or symptom.

Time frame: Entry, Week 8, and Week 24

Population: Subjects who had at least one event that was possibly, probably, or definitely related to vaccine.

Percentage of Participants Who Reported a Lower Need to Practice Safe Sex Following HPV Vaccination and the Percentage of Participants That Reported a Higher Need to Practice Safe Sex Following HPV Vaccination

Participants' perceptions for the need to practice safe sex following HPV vaccination was measured using a safer sexual behaviors subscale, which was comprised of the following five questions: After getting vaccinated against HPV … 1. You feel that condom use during sex is less necessary. 2. You feel it is still just as important to have as few sexual partners as possible. 3. You feel that it is less important to talk to your sex partners about safe sex. 4. You think it is still just as important to use a condom every time you have sex. 5. You will be less worried about having unprotected sex. Those who were categorized in the lower need for safer sexual behaviors (NSSB) group had a summary score that was less than the median and those in the higher NSSB group had a summary score that was equal to or higher than the median.
