The 100th anniversary of the BCG vaccine was in 2021. [11] It remains the only vaccine licensed against tuberculosis, which is an ongoing pandemic . Tuberculosis elimination is a goal of the World Health Organization (WHO), although the development of new vaccines with greater efficacy against adult pulmonary tuberculosis may be needed to make ...
The only available vaccine as of 2021 is bacillus Calmette-Guérin (BCG). [116] [117] In children it decreases the risk of getting the infection by 20% and the risk of infection turning into active disease by nearly 60%. [118] It is the most widely used vaccine worldwide, with more than 90% of all children being vaccinated. [15]
Improperly treated tuberculosis. Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB). Almost one in four people in the world is infected ...

Tumor antigen vaccines work the same way that viral vaccines work, by training the immune system to attack cells that contain the antigens in the vaccine. The difference is that the antigens for viral vaccines are derived from viruses or cells infected with virus, while the antigens for tumor antigen vaccines are derived from cancer cells.
rBCG30 ( recombinant Bacillus Calmette-Guérin 30) is a prospective Bacillus Calmette-Guérin vaccine against tuberculosis. It is a live vaccine, consisting of BCG, which has been evaluated as a tuberculosis vaccination. It is genetically modified to produce abundant amounts of mycolyl transferase, a 30 kDa antigen (Antigen 85B) [1] that has ...
