Differences in the number of IFN+ T lymphocytes induced by the PP13138R vaccine in HCs, ATB patients, and LTBI individuals. PMBCs collected from HCs (A), ATB patients (B), and LTBI individuals (C) were stimulated with the PP13138R vaccine or AIM-V medium, and the number of IFN+ T lymphocytes were detected using ELISPOT. The data were shown as mean + SEM and analyzed using the Unpaired t-test or Mann Whitney test according to the normality. P<0.05 was considered significantly different. SEM, standard error of the mean; SFCs, spot-forming cells.
