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.

I was going to mention. In the states you only need it if you are going for a Greencard (perhaps citizenship as well). It's not a routine vaccination. I got the skin test (tested negative), the vaccine and then another skin test a few days later I believe.
