The purpose of this study was to assess the influence of Haemophilus influenzae type b conjugate vaccine on HIV-1 RNA level, CD4 count, and anti-Hib polysaccharide (PRP) antibody concentration. Eighty HIV-infected adults were randomized to receive Hib conjugate vaccine or not. Twenty HIV-seronegative controls were also vaccinated. Blood samples were taken before and after vaccination, with a follow-up period of 6 months. HIV infection markers and anti-PRP antibodies were monitored. There was no change in either HIV-1 viremia or CD4 count after vaccination. Immunization immunogenicity was superior in HIV-uninfected than in HIV-infected individuals (p < 0.01). Hib vaccination was safe but induced suboptimal antibody response in HIV-infected adults.
