Pilot Study to Evaluate the Immunogenicity and Safety of the HPV Quadrivalent Vaccine (Gardasil) in HIV-infected Men
This is a prospective pilot study that will attempt to enroll approximately 150-200
HIV-infected males followed regularly in the ID Primary Care Clinic at the VA Long Beach
Healthcare System. All consenting patients will be given the HPV vaccine (Gardasil) in
three intramuscular injections. Baseline antibody titers to HPV strains 16 and 18 will be
obtained at day 0 and repeat levels will be obtained approximately 8 weeks after the
completion of the vaccination series to determine whether patients without antibodies at
baseline have now produced antibodies, or to determine the change in antibody levels in
those patients who have evidence of antibodies prior to the first injection of the vaccine.
Patients will undergo routine anal PAP smear with HPV DNA testing at baseline and another
PAP smear/HPV test approximately 8 weeks after completion of the series. Patients will
report any side effects of the vaccine to the PI. Patients will have blood work to monitor
HIV-1 viral load and CD4 lymphocytes counts at various points during the study.
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Prevention
