Pneumococcal Vaccines HIV HIV Infections | Biological: Prevenar and Pneumo23 | Phase 3 |
Randomised study comparing two pneumococcal vaccination strategies in HIV-infected adults with moderate immunossupression (CD4 between 200 and 500 cells/uL and viral load under 5logs), one with conjugated heptavalent vaccine(Prevenar, Wyeth-Lederle) followed by polysaccharide vaccine 4 weeks after (Aventis-Pasteur), and two with one dose of polysaccharide vaccine. A sample of 220 HIV-infected adults will be randomised to receive twe strategy one(110 patients) one dose of heptavalent conjugated vaccine at day 0 and one dose of polysaccharide vaccine at week 4 (in deltoid muscle); or strategy two (110 patients) one dose of polysaccharide vaccine at day 0. Secondary effects to the vaccines will be evaluated by phone interview 3 days after vaccinations.
Blood samples will be taken at day 0(before the first vaccine), at week 4 before the polysaccharide in the group one, and 4 weeks after the polysaccharide in the group two) and at week 8 in the group one, and at weeks 48 and 96 in both groups Antibody concentration , avidity, and opsonophagocytic killing activity will be measured in all the samples for serotypes 4,14,19F,23F,6B,18C,9V.
Antibody concentration , avidity, and opsonophagocytic killing activity will be compared between both vaccine groups, and between prevaccination and at 4,8, 48 and 96 weeks of vaccination. Risk factors associated to good antibody response (antibody duplication and antibody duplication plus achieve a level above 1ug/ml)will be measured at 8, 48 and96 weeks.

Experimental: two vaccines
people allocated to arm two vaccines will receive one dose of heptavalent pneumococcal conjugate vaccine at day 0 and 23-valent polysaccharide vaccine at week4 , 110 HIV-infected people will be included Intervention: administration of two vaccines

Biological: Prevenar and Pneumo23
Two vaccines: participants will receive via intramuscular in deltoid one dose of conjugated heptavalent vaccine at day 0 (Prevenar, Wyeth-lederle)and one dose of 23valent polysaccharide vaccine (Pneumo23, AventisPasteur)at week4 One vaccine:participants will receive only one dose of 23valent polysaccharide vaccine at day 0.

Experimental: One vaccine
people allocated to arm one will receive only one doses of pneumococcal polysaccharide 23-valent vaccine. 110 HIV-infected adults will be included in this arm Intervention: administration of one vaccine

- Antibody response in terms of antibody concentration at 4,8,48 and 69 weeks of vaccination [ Time Frame: 4, 8, 48 and 96 weeks of vaccination ]
- Avidity of the antibodies induced in the two vaccination groups before and at 4 ,8 , 48 and 96 weeks of vaccination [ Time Frame: 4 , 8 ,48 and 96 weeks after vaccintation ]
- safety of both vaccines [ Time Frame: 3 days ]
- risk factors associated to a good vaccine response [ Time Frame: 8 weeks, 48 weeks, 96 weeks ]
- opsonophagocytic activity against the seven polysaccharides before, and after 4,8,48 and 96 weeks of vaccination [ Time Frame: 4,8,48 and 96 weeks ]
