Extended Data Fig. 3: Analysis of SARS-CoV-2-specific T cells.
From: Immunogenicity and efficacy of heterologous ChAdOx1–BNT162b2 vaccination
PBMCs were stimulated as detailed in the methods and stained for CD3, CD4, CD8, CD14, CD56 and CD19 expression and with a dead cell marker. Cells were gated from left to right and top to bottom. The Viab/dump channel includes antibodies against CD14, CD19, CD56 and a viability marker. The frequency of CD4 or CD8 T cells positive for intracellular IFNg was measured as shown in the central and right bottom panels.
