Tuberculosis vaccine is not routinely used in North America. There is considerable dispute in the scientific community as to whether the vaccine (BCG) adequately or even inicidentally protects vaccinees against TB.
Generally North American health authorities don't use the vaccine so that the PPD skin test for TB exposure can be used to determine exposure. Vaccinated people often report positive for these tests.
