Effect of human immunodeficiency virus type 1 infection on the antibody response to a glycoprotein conjugate pneumococcal vaccine: results from a randomized trial.
Adults (n = 282) were randomized to receive either a pneumococcal glycoprotein conjugate vaccine, composed of pneumococcal serotypes 6B, 14, 18C, 19F, and 23F linked to CRM197, or a 23-valent pneumococcal polysaccharide vaccine. Among human immunodeficiency virus (HIV)-uninfected persons, conjugate vaccine elicited significantly higher IgG antibody geometric mean titers (GMTs) than did polysaccharide vaccine for serotypes 6B, 18C, and 23F: IgG GMTs were 9.0 versus 4.8, 23.2 versus 5.9, and 15.3 versus 4.4 micrograms/mL, respectively. In contrast, the two vaccines elicited similar antibody GMTs in HIV-infected persons: GMTs ranged from 1.3 to 10.8 micrograms/mL for all serotypes. Of note, among persons receiving polysaccharide vaccine, antibody GMTs in HIV-uninfected and -infected persons with CD4 lymphocytes > or = 500/microL were similar. These data underscore the importance of controlled clinical evaluations of newer pneumococcal vaccines in all high-risk groups for whom pneumococcal immunization is recommended and highlight the need for early immunization of HIV-infected persons with currently available polysaccharide vaccines.
