Reactogenicity to major tuberculosis antigens absent in BCG is linked to improved protection against Mycobacterium tuberculosis

Abstract

MTBVAC, a live attenuatedMycobacterium tuberculosisvaccine under clinical evaluation, contains the major tuberculosis antigens ESAT6 and CFP10, which are absent from the current vaccine, BCG. Here, the authors show that these antigens contribute to enhanced vaccine efficacy in mouse models.
