Safety and Immunogenicity of 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) in HIV-Infected Subjects 6 Years of Age or Older Who Are Naive to Pneumococcal Vaccine

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.
