M72/AS01 E is an experimental tuberculosis vaccine. If approved, it would be the first vaccine for tuberculosis in more than a century after the BCG vaccine.

Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death ...
