Expansion of human influenza-specific T cells in vitro after stimulation of autologous DC with different virosome SLP vaccine formulations. A % CD8 + T cells (of live CD3 + cells), B Tetramer positive CD8 T cells (of live CD3 + cells). Preparations tested were: buffer only (unstimulated), peptide alone (SLP), Amplivant-SLP (SLP-AV), virosomes without antigen (Placebo virosomes), virosomes containing Amplivant; H,M,L: concentrations of virosome-included 3D-PHAD 0.95 µg/ml (H) 0.19 µg/ml (M) 0.038 µg/ml (L), and QS-21 H: 0.95 µg/ml, M, 0.38 µg/ml, L: 0.076 µg/ml. SLP concentration was 1 nmol/ml
