Fig. 6From: HIV-Tat immunization induces cross-clade neutralizing antibodies and CD4+ T cell increases in antiretroviral-treated South African volunteers: a randomized phase II clinical trialNeutralization of B- and C-clade Tat/Env complex entry in DC in vaccinees. Neutralization of B- (n = 13) and C- (n = 10) clade Env entry in DC in the presence or absence of (B- or C-clade) Tat by sera of Ab-positive vaccinees, measured at week 20 or week 48 after immunization. Data are presented as mean values with standard errors. Student’s t test for paired data was used for the analysesBack to article page
