Longitudinal analysis of the phenotype of YF-tetramer positive CD8⁺ T-cells on days 12, 28 and 180 in singly vaccinated individuals.

<p>A Dot plots of a representative donor. Cells are gated on total CD8⁺ T-cells (in grey) and YF-tetramer positive cells (in black). B-D Summary of percentages of tetramer positive cells expressing CD45RA, CD27, granzyme K, granzyme B and Ki67 in 6 donors (1 donor had 2 matching HLA types). Comparisons were performed with a paired Wilcoxon Rank sum test. ns = not significant.
