Purpose
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.

Primary Outcome Measures:
- Number of serotypes to which a response is found
- A response is defined as a doubling in antibody titer at 1 month compared to baseline.
Secondary Outcome Measures:
- Antibody response at 6 months and one year
- Changes in viral load 3 months post immunization
- Adverse events
- Overall incidence of invasive pneumococcal disease
- Incidence of invasive pneumococcal disease between vaccines
| Estimated Enrollment: | 80 |
| Study Start Date: | April 2003 |
A multicentre, randomized controlled trial using a two factorial design. Eighty patients will be randomly assigned to receive either Pneumovax (or Pneumo23 according to standard use at site) or heptavalent pneumococcal conjugate vaccine (Prevnar) prior to reconstitution of the immune system or will have immunization delayed until their CD4 count is greater than 200 cells/mm3 after the introduction of antiretroviral therapy. Randomization will be stratified by study centre. Variable block sizes will be used to try to prevent study personnel from guessing the next allocation. Random allocation lists will be generated by computer.
