BCG Recommendations
In the United States, BCG should be considered for only very select people who meet specific criteria and in consultation with a TB expert. Health care providers who are considering BCG vaccination for their patients are encouraged to discuss this intervention with the TB control program in their area.
children :-
Children vaccination should only be considered for children who have a negative TB test and who are continually exposed, and cannot be separated from adults who
Are untreated or ineffectively treated for tb, and the child cannot be given long-term primary preventive treatment for TB infection; or
Have TB disease caused by strains resistant to isoniazid and rifampin.
Health Care Workers
BCG vaccination of health care workers should be considered on an individual basis in settings in which
- A high percentage of TB patients are infected with TB strains resistant to both isoniazid and rifampin;
- There is ongoing transmission of drug-resistant TB strains to health care workers and subsequent infection is likely; or
- Comprehensive TB infection-control precautions have been implemented, but have not been successful.
