Figure 1. Virological outcome in Tat/Env-vaccinated or control monkeys after intrarectal challenge with the SHIV_SF162P4cy (70 MID₅₀).

Box plots of (A) Viral RNA, (B) proviral DNA in blood at 2, 3, 4 and 5 weeks after challenge, respectively; and (C) proviral DNA at week 4 after challenge in rectal tissue (RT) and inguinal lymph nodes (LN). Statistical analysis was performed by the one-sided Wilcoxon rank sum test. Red: monkeys vaccinated with Tat/Env (n = 6); blue: control animals (n = 6).
