Fig. 5

Total IgG (A) and IgA (B) against Purified Protein Derivative (PPD) were measured using a standardised in-house indirect ELISA. Arbitrary units (AU). Statistically significant differences are presented in the figure. IgG serum: D56 p = 0.0155 two-sided Wilcoxon, no significance after Dunnett’s correction. See Supplementary Note 2 and source data (provided as a Source Data file) for sample sizes per group. Black dots indicate BCG, grey squares saline control. Box and whisker plots show median, IQR and min/max, crosses show mean.
