TABLE 6.

Duration of the antibody response during and after priming with DNA + V1V2_ZM53-2J9C and boosting with V1V2_A244-2J9C (experimental group H4/4)^a

^aValues are the mean ODs at 405 nm of five sera tested at 1:100. Data from 36 prebleed sera in various experiments were used to calculate a cutoff value (mean + 3 standard deviations) of ≥0.14. The results during priming are shown in bleeds I and II, and those during and after boosts are represented in bleeds III to IX (indicated by the black line). Abbreviations for the prime-boost regimen use the following form: 2wp1p, 2 weeks post-1st prime; 2wp1b, 2 weeks post-1st boost. V3 ConsC, V3 consensus C peptide.
