Activation status changes rapidly after vaccination.

A) Total Ki67⁺ among γδTCR⁺. B) Proportionality in the segments day 0 to 3 and C) day 7 to day 21. D) CD38⁺Ki67⁺ among γδTCR⁺. E) Proportionality in the segments day 0 to 3, and F) day 7 to day 21. The box in figures A and D represents the 25^th, 50^th, and 75^th percentile and the whiskers the range excluding outliers (open circles). Asterisks indicate p-values (*** < 0.001; ** p < 0.01; * p < 0.05) after comparison with Student's t-test. p-values were corrected by the FDR method and only significant differences are shown. The two age groups in figures B, C, E, and F are slightly offset to the day of measurement to improve the visualization. Each point represents a single donor. The formula y = β + αx was fitted in B and E. The formula y = β + α/x was fitted in C and F. The given values indicate the proportionality constant α.
