Brief Summary
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. Determination of secondary effects related to both vaccines and determination of antibody concentration (ELISA) and avidity (ELISA with thiocyanate) and opsonophagocytosis killing activity against the seven serotypes included in the heptavalent vaccine before vaccination, at 4 weeks, at 8 weeks, at48 weeks and 96 weeks. A sample of 220 HIV-infected adults (110 in each group) will be needed to detect differences of 10% for a type I error o 5% for a limited population of 2500 HIV-infected adults. The main hypothesis are :the immunogenicity of pneumococcal vaccination with conjugate and polysaccharide vaccines is superior to immunogenicity induced by polysaccharide vaccination alone(antibody concentration), the avidity and opsonophagocytosis induced by two vaccines is better than the one after polysaccharide vaccine alone, both vaccinations are safe.

Study Arms (2)
two vaccines
EXPERIMENTALpeople 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
One vaccine
EXPERIMENTALpeople 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
Interventions
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.
