A new study from Public Health England (PHE) published in the British Medical Journal found that Bacillus Calmette-Guérin (BCG) vaccine may protect against M. tuberculosis (TB) infection, in addition to decreasing progression of TB from infection to disease.
Previously, it has has been widely accepted that BCG vaccine protects against the most severe forms of disease such as TB meningitis in children. This review of existing research indicates BCG vaccine can also protect against an individual becoming infected.
