FIG. 2.

Peripheral blood immune findings significantly associated with the presence or absence of a BCG vaccine scar in participants <6 months old. (A) Percentages of lymphocytes making IL-4 with stimulation; (B) ratios of the percentages of CD3⁺ cells making IL-10 to the percentages of those making IL-4 with stimulation; (C) ratios of the percentages of monocytes making IL-10 to the percentages of those making IL-6 with stimulation. Note that y axis scales differ among the panels. One outlier is excluded from the graph: for one child without a BCG scar, 23% of lymphocytes made IL-4 with stimulation. When this value is excluded from statistical calculations, results remain significant. Solid circles, individuals in the BCG scar-negative group who had inflammation at the BCG vaccination site but no scarring.
