While Mycobacterium bovis, or bacille Calmette-Guerin,
has been administered to newborns for generations for the prevention of
childhood tuberculosis, its effectiveness as a preventative against reactivation
pulmonary disease or HIV-associated tuberculosis is minimal. A number
of promising candidates for a more effective tuberculosis have been created and
some are in development, but the lack of a preventive for such a wide range of
pulmonary diseases highlights the importance of discovering such a vaccine
quickly. Researchers are studying a variety of vaccine techniques, including
using attenuated or enhanced whole-cell
live vaccines, whole-cell inactivated products, and subunit, DNA, and
prime-boost vaccines. A few have even demonstrated effectiveness into animal
trials, but such a vaccine will take years to reach the market. The delay will
be due to the fact that there has been no marker found to identify immunity
against tuberculosis. As a result, any truly effective vaccine will require
going through years of testing and follow-up data gathering to determine its
effectiveness in preventing tuberculosis in patients.
