Immune Responses to Pneumococcal Vaccination Among HIV-infected Subjects
Immune Responses to Pneumococcal Vaccination Among HIV-Infected Subjects

The purpose of this study is to evaluate the best timing for administering pneumococcal vaccine (PV) to HIV-infected adults that have CD4 cell counts of more than 200 and are not yet receiving combination antiretroviral treatment (ART). Participants in this study will be assigned by chance to receive vaccination with PV prior to starting ART or after at least 6 months of ART. Antibody levels to components of the PV will be measured at 6 months and 12 months after vaccination. The results will tell us if patients that receive PV after 6 months of ART have better response to the vaccine than those that get vaccinated prior to treatment.

Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver)
Primary Purpose: Prevention
HIV Infections
  • Biological: 23-valent pneumococcal polysaccharide vaccine
    Currently commercially available pneumococcal polysaccharide vaccine
  • Biological: Placebo
    Arm 2 will receive placebo prior to starting antiretroviral treatment and will receive PV after at least 6 months of starting antiretroviral treatment
  • Arm 1
    Both groups will receive PV, the intervention is the time for vaccination (before or after starting antiretroviral treatment).
    Intervention: Biological: 23-valent pneumococcal polysaccharide vaccine
  • Placebo Comparator: Arm 2
    Arm 2 will receive placebo prior to starting antiretroviral treatment and will receive PV after at least 6 months of starting antiretroviral treatment.
    Intervention: Biological: Placebo
