Extended Data Fig. 10: Flow cytometry analyses.

Flow cytometry analyses. a, Representative flow plots showing the gating strategy for flow cytometry analysis of intracellular cytokine staining to determine cytokine expression by CD4 and CD8 T lymphocytes upon stimulation with vaccine-insert matched peptide pools. b, Representative flow plots showing the gating strategy for flow cytometry analysis to determine the frequency of PKH26+CFSE- target cells. Each sample was run in triplicates and the average was calculated. c, Flow cytometry gating scheme used to quantitate monocytic THP-1 ADCP is shown for representative plasmas sample collected at baseline (left) and week 50 (right) from a vaccinated individual. THP-1 cells were gated on based on FSC-A and SSC-A. Then, doublets were excluded based on low outlier events for FSC-H against FSC-A. Final histogram gating was used to determine bead positive THP-1 cells. The phagocytic score was calculated by multiplying the percentage of bead-positive cells by the geometric mean fluorescence intensity of the bead-positive cells and dividing by 104. Each sample was run in duplicate and the average was calculated.
