Fig 5. Binding antibody responses of vaccinees tested four weeks after the second HIV-MVA vaccination.

Binding antibody titers to subtype B (IIIB) gp160 (A) and to subtype C (HIV-1 96ZM651) gp140 (B) envelope proteins are shown. The lowest dilution used was 1:100. The dashed line is therefore set at 100. Negative values were arbitrarily given a value of 50. Placebo recipients are given as open circles.
