* Meets one of the following sets of criteria:

  * Patients receiving antiretroviral therapy:

    * Receipt of antiretroviral therapy for at least 3 months prior to entry
    * No change in antiretroviral therapy within 30 days prior to entry
  * Patients not receiving antiretroviral therapy:

    * CD4-cell count ≥ 350 cells/mm³ within 90 days prior to study entry
    * No plans to start antiretroviral therapy prior to Week 28
* Normal anal cytological result, LSIL/condyloma, or ASCUS result within 90 days prior to entry, and no HGAIN on biopsy

  * No current or history of anal or peri-anal carcinoma
  * No anal cytological result of HSIL, atypical squamous cells suggestive of HSIL (ASC-H), or suggestive of invasive carcinoma at screening; or history of these results
* No presence of penile or scrotal condyloma, LGAIN (condyloma or AIN 1), HGAIN (e.g., AIN 2 or 3, or perianal intraepithelial neoplasia grade 2 or 3), or invasive carcinoma at pre-entry on biopsy
* No history of HGAIN

PATIENT CHARACTERISTICS:

* Karnofsky performance score ≥ 70 within 45 days prior to entry
* Absolute neutrophil count (ANC) \> 750 cells/mm\^3
* Hemoglobin ≥ 9.0 g/dL
* Platelet count ≥ 100,000/mm\^3
* AST (SGOT), ALT (SGPT) ≤ 3 times upper limit of normal (ULN)
* Total or conjugated (direct) bilirubin ≤ 2.5 times ULN within 45 days before study entry, with the exception of isolated hyperbilirubinemia that is considered due to atazanavir
* Calculated creatinine clearance ≥ 60 mL/min
* No hemophilia
* No active drug or alcohol use or dependence that, in the opinion of the site Investigator, would interfere with adherence to study requirements
* No serious illness requiring systemic treatment and/or hospitalization within 45 days prior to entry
* No serious medical or psychiatric illness that, in the opinion of the site Investigator, will interfere with the ability of the subject to give informed consent or adhere to the protocol
* No allergy to yeast or any of the components of Gardasil

PRIOR CONCURRENT THERAPY:

* See Disease Characteristics
* No prior splenectomy
* No prior receipt of Gardasil or other HPV vaccine
* No use of any systemic antineoplastic or immunomodulatory treatment, systemic corticosteroids for greater than 14 days, investigational vaccines, interleukins, interferons, growth factors, or IVIG within 45 days prior to study entry
* No expected use of any systemic antineoplastic or immunomodulatory treatment, systemic corticosteroids used for greater than 14 days, investigational vaccines, interleukins, interferons, growth factors, or IVIG during study followup

  * No patients with hepatitis C who expect to initiate treatment for hepatitis C (e.g., interferons) during this trial
