NCT00137605

Brief Summary

The purpose of this study is to determine whether people who are HIV-positive respond better to a vaccine for pneumonia-related disease when they are immunized immediately, or when immunization is delayed until the immune system has improved to a certain level. The study will also compare the effectiveness of polysaccharide and heptavalent vaccines.

  • Changes in viral load 3 months post immunization

  • Adverse events

  • Overall incidence of invasive pneumococcal disease

  • Incidence of invasive pneumococcal disease between vaccines
