Abstract:

Tuberculosis (TB) remains one of the most severe single infectious diseases leading to high mortality in the world. Bacille Calmette-Guérin (BCG) is the only licensed preventive TB vaccine, which is routinely administered in newborns in high burden countries including China, and provides significant protection against TB. However, recent researches reveal that the protection provided by BCG is time-sensitive, especially declined in adults. Therefore, how to reform BCG to augment the protective immunity against TB becomes one of the principal strategies in the vaccine development and the prevention of infection. Herein, the authors will review the research progress to discuss about the current status in BCG vaccine development and vaccination strategies and their future application.
