At 30 and 60 days post infection the number of splenic TCM cells increased significantly in animals that received clofazimine during BCG revaccination in both the CD4+ and CD8+ T cell lineages, as compared with animals that received BCG vaccination, BCG-revaccination, or BCG-revaccination with INH treatment (Fig 2A and 2B). Here, CD8A is linked to infection.
