Abstract
Vaccine-induced T-cell memory for human immunodeficiency virus type 1 (HIV-1) was assessed by measuring HIV-1 antigen-stimulated cytokine secretion in 72 HIV-1-uninfected subjects, of whom 52 received live recombinant canarypox virus vaccine expressing HIV-1 env, gag, and protease gene products (vCP205) with or without HIV-1(SF-2) recombinant gp120 (SF-2 rgp120) subunit vaccine, and 20 the control. The vCP205 vaccine induced secretion of the Th1 cytokine, interferon-gamma, by peripheral blood mononuclear cells (PBMC) after in vitro stimulation with HIV-1 p24 and envelope glycoprotein. Immunization schedules with both vCP205 and SF-2 rgp120 subunit vaccines induced secretion of Th1 and Th2 cytokines by PBMC to HIV-1 envelope glycoprotein. Hence, vCP205 and SF-2 rgp120 subunit vaccines given together and in a prime-boost sequence appeared to induce a broader cytokine response pattern than vCP205 vaccine given alone.
