Lymphoproliferative responses are shown as Stimulation Index (SI) to virion HIV-1 MN (A), recombinant Gag p24 (B) and recombinant RT (C) viral antigens among vaccinated (n = 10; black dots and lines) and controls (n = 10; grey squares and lines).

<p>Black arrows show vaccinations (weeks 0, 4, 12 and 36).</p

Viral dynamics during the vaccination schedule for the control Group A (n = 10) (A) and vaccine Group B (n = 10) (B).

<p>HIV-RNA with a limit of detection of 50 copies/ml is shown as black dots, HIV-RNA ultrasensitive assay with a limit of detection of 1 copy/ml plasma is shown as circles and cell associated HIV-DNA of PBMC shown as triangles indicating number of total HIV-proviral DNA copies/10⁶ PBMC. Black arrows show vaccinations (weeks 0, 4, 12 and 36).</p

Safety Profile of the PEDVAC trial: distribution of adverse events during the 96 weeks follow-up of the study.

<p>The black dashed line shows total number of solicited and unsolicited adverse events in control Group A. The gray dashed line indicates total number of solicited and unsolicited adverse events in vaccine Group B, while the black solid line indicates all local and systemic adverse events which were vaccine related. Black arrows show vaccinations (weeks 0, 4, 12 and 36).</p

Functional profiles of between groups HIV-specific CD4+ and CD8+ T-cells analyzed by ICS at weeks 0, 16, 20 and 60.

<p>The panels show the percentage of T-cells releasing IFN-γ (A) and IL-2 (B) for CD4+ T-cells, and IFN-γ (C) and perforin (D) for CD8+ T-cells for each patient in control Group A (n = 10, circles), and vaccine Group B (n = 10, black dots). T-cell functions were analyzed after stimulation for 16 h with a pool of proteins representing the vaccine sequences. Lines represent median values. In panel (E) CD8+ cells releasing perforin at baseline week 0 and after 60 weeks in vaccine and control groups are shown. Differences within groups between baseline and week 60 levels in panel (E) are indicated for each individual, and the p-value calculated by Wilcoxon signed rank test.</p
