Tubercular meningitis; TB meningitis
In areas where tuberculosis is more common, the BCG vaccine may help prevent severe forms of tuberculosis, such as meningitis, in very young children.
Treating people who have evidence of a non-active (dormant) tuberculosis infection can prevent the spread of tuberculosis. A dormant infection can be detected by a positive PPD.
