A new and improved vaccine against tuberculosis (TB) would provide a powerful tool to conquer one of the most insidious infectious diseases of mankind. Protection afforded by Bacille Calmette-Guerin (BCG) has been shown to be limited and inconsistent, especially in adults that are known to transmit TB disease. In the last two decades, several new vaccines have been developed and tested with the aim to elicit robust and long-lived T cell responses against Mycobacterium tuberculosis antigens. Although much progress has been made in the TB vaccine field, there is an urgent need to address critical research questions about TB immunity with a special focus on designing vaccines aimed at preventing infection and transmission of TB. Here, we discuss the rationale behind the current immunization strategies being implemented for TB vaccines and provide some suggestions for hypothesis driven research to encourage the development of novel TB vaccines.
