Prevention of TB involves screening those at high risk, early detection and treatment of cases, and vaccination with the bacillus Calmette-Guérin (BCG) vaccine. [3] [4] [5] Those at high risk include household, workplace, and social contacts of people with active TB. [4] Treatment requires the use of multiple antibiotics over a long period of ...
The WHO recommends childhood BCG for all countries with a high incidence of tuberculosis and/or high leprosy burden. [9] This is a partial list of historic and active BCG practices around the globe. A complete atlas of past and present practice has been generated. [50] As of 2022, 155 countries offer the BCG vaccine in their schedule. [51]

[ 1 ] As of 2021, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921.
Prospects for tuberculosis control and elimination in a hypothetical high-burden country, starting in 2015. Tuberculosis has been a curable illness since the 1940s when the first drugs became available, although multidrug-resistant and extensively drug-resistant TB present an increasing challenge. [5]
