BCG is still given at birth to babies born into high risk groups. These includes those who have a family history of tuberculosis, ethnic minorities at increased risk of TB and those born in areas with a high prevalence.
BCG is also given to those who may be at risk of increased exposure to tuberculosis such as health care workers.
Is the policy of BCG vaccination the same throughout the world?
No, mainly because of variation in trial results. Most countries give BCG at birth to provide protection in the early years when infection can often lead to devastating widespread disease such as miliary tuberculosis or tuberculous meningitis. This is particularly important in high prevalence countries where the chance of being infected in very early life is high. Some countries such as the USA have chosen not to use it because most trials there have not shown any protective effect.
Why is there not international agreement on how to use BCG?
Again because of variation in trial results across the world.
