  Purpose

The study will evaluate the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate vaccine (13vPnC) in HIV-infected subjects 6 years of age or older who have not been previously immunized with a pneumococcal vaccine. All subjects will receive 3 doses of 13vPnC and 1 dose of 23-valent pneumococcal polysaccharide vaccine (23vPS), with each dose given approximately 1 month apart.

Primary Outcome Measures:
  • Immune responses after 2 and 3 doses of 13vPnC as measured by serotype-specific immunoglobulin G (IgG) geometric mean fold rises (GMFRs) in all subjects. [ Time Frame: 1 month after 3 doses of 13vPnC (approx. 3 months) ] [ Designated as safety issue: No ]
  • Safety of 13vPnC measured by local reactions, systemic events. [ Time Frame: 14 days post-vaccination, doses 1- 3 ] [ Designated as safety issue: Yes ]
  • Safety of 13vPnC measured by adverse events. [ Time Frame: Ongoing through study ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Immune responses after each dose of study vaccine as measured by IgG in all subjects. [ Time Frame: 1 month post-vaccination, doses 1-4 ] [ Designated as safety issue: No ]
  • Immune responses after each dose of study vaccine as measured by IgG in the pediatric & adult subgroups. [ Time Frame: 1 month post-vaccination, doses 1-4 ] [ Designated as safety issue: No ]
  • Immune responses after each dose of study vaccine as measured by opsonophagocytic activity in all subjects. [ Time Frame: 1 month post-vaccination, doses 1-4 ] [ Designated as safety issue: No ]
  • Immune responses after each dose of study vaccine as measured by opsonophagocytic activity in the pediatric & adult subgroups. [ Time Frame: 1 month post-vaccination, doses 1-4 ] [ Designated as safety issue: No ]
