Participant Flow

345 is the number of potential subjects that was approved for enrollment by the IRB (Group 1 PCV = 210; Group 2 PPV = 110; Group 3 HIV-negative = 25). 275 is the total number of subjects who actually consented to participate. 229 is the number of subject who were vaccinated. In 2008, the DSMB voted unanimously to recommend no further enrollment.

Measure
Group 1 - PCV
PCV, 210 patients pneumococcal conjugate vaccine: Prevnar is manufactured as a liquid preparation. Each 0.5 mL dose is formulated to contain: 2 μg of each saccharide for serotypes 4, 9V, 14, 18C, 19F, and 23F, and 4 μg of serotype 6B per dose (16 μg total saccharide); approximately 20 μg of CRM197 carrier protein; and 0.125 mg of aluminum per 0.5 mL dose as aluminum phosphate adjuvant. After shaking, the vaccine is a homogeneous, white suspension.
Group 2 - PPV
PPV, 110 patients pneumococcal polysaccharide vaccine: PNEUMOVAX 23 is manufactured according to methods developed by the Merck Research Laboratories. Each 0.5 mL dose of vaccine contains 25 μg of each polysaccharide type in isotonic saline solution containing 0.25% phenol as a preservative.
Group 3 - HIV-negative
PCV, HIV-negative, 25 patients pneumococcal conjugate vaccine: Prevnar is manufactured as a liquid preparation. Each 0.5 mL dose is formulated to contain: 2 μg of each saccharide for serotypes 4, 9V, 14, 18C, 19F, and 23F, and 4 μg of serotype 6B per dose (16 μg total saccharide); approximately 20 μg of CRM197 carrier protein; and 0.125 mg of aluminum per 0.5 mL dose as aluminum phosphate adjuvant.

Population: Number of participants analyzed for each time frame: Group 1 (Day 14=129/131; Day 60=123/131; Day 180=119/131); Group 2 (Day 14=69/73; Day 60=67/73; Day 180=67/73). Group 3 = 0 since these data are not applicable to HIV-negative subjects.

The pairwise change in CD4+ cell count from the time of screening to each time frame (day 14, day 60 and day 180 post-vaccination) (CD4+ cell count at day 14/60/180 \[minus\] CD4+ cell count at screening). Analysis Population Description (further details): not all participants completed each follow-up visit. Therefore, a different number of participants analyzed is noted for each visit day. For example, in Group 1, 131 participants completed the screening visit but only 129 completed Day 14, and only 123 completed Day 60, etc.
