Can BCG vaccines to be given a adult with Mantoux Positive who have no symptoms of Tuberculosis ??


People who were previously vaccinated with BCG may receive a TB skin test to test for TB infection. Vaccination with BCG may cause a false positive reaction to a TB skin test. A positive reaction to a TB skin test may be due to the BCG vaccine itself or due to infection with TB bacteria.
