Changes in antibody reactivity to the C and V epitopes after HIV infection

INFECTION, HIV INFECTION
We next compared antibody reactivity to the C and V epitopes at the pre-infection visit and the first HIV-positive visit (baseline, infection duration 0-1 year). VirScan data were available at baseline for 145/148 participants, including 7/8 participants with pre-infection reactivity to the C epitope and 42/43 participants with pre-infection reactivity to the V epitope. (At baseline, almost all participants (143/145 [98.6%]) had C epitope reactivity; this included all seven participants with pre-infection reactivity to this epitope (Antibody reactivity to the C and V epitopes before and after HIV infection. The plots show the level of antibody reactivity (logDifferent patterns of antibody reactivity were observed for the V epitope. Only 37/145 (25.5%) participants had reactivity to the V epitope at baseline (
