Multi-Functional Flow Cytometry Results (Env peptide pool responses)^*.

*The number of positive responses for each function is shown (bolded) as measured at 2 weeks after the third vaccation (day 98). The quantitative values (median and range) represent the corrected value (test antigen - background) for the responses scored as positive. **6 placebo recipients were tested in the same assay procedure with a two false positives scored for CD107a (one CD4+ and one CD8+) at a pre-vaccination visit.
