HIV-1 Tat B-cell epitope vaccination was ineffectual in preventing viral rebound after ART cessation

HIV rebound with current ART appears to be due to infection with new endogenous founder virus and not to resurgence of pre-existing Tat-dependent viremia

Figure 3. Changes in anti-Tat antibody levels after TUTI-16 (blue) or placebo (red) injections. Arrows denote injection times. The blue lines and symbols represent individual vaccinated subjects. The red line and symbols show the non-responsiveness of the placebo group and two non-responding vaccine subjects are concealed behind this line. TUTI-16 induced antibody levels < 40 ng/mL were previously shown to lower plasma HIV levels in asymptomatic ART naïve HIV infected subjects.Citation18
