FIG 6.

A(H1N1)pdm09-specific CD8⁺ T-cell responses in study B. The graphs shown represent antigen-specific CD8⁺ T-cell responses induced by the AS03-adjuvanted or nonadjuvanted A(H1N1)pdm09 (H1N1) vaccine measured after stimulation with H1N1 split antigen. Data are stratified either by age (A) or by the participants' history of seasonal influenza vaccination (Flu/No flu; B) and reported as percentages of A(H1N1)pdm09-specific CD8⁺ T cells expressing at least two immune markers (IFN-γ, IL-2, TNF-α, or CD40L). y, years. M, month. Q1 and Q3, first and third quartiles. Min and Max, minimum and maximum values.
