This prospective trial was realized in 371 children previously vaccinated with BCG in the first month of life in whom the Mantoux tuberculin test was done and read 48-72 hours afterwards. Among 371 BCG-vaccinated children, 106 (28,57%) were Mantoux reactive, 10 of whom with clinical tuberculosis. There was no statistically significant difference in the tuberculin test between the control group (59 non-BCG-vaccinated children) and 180 vaccinated children, considering those under 6 years old. When we compared by age, we verified that just 36,36% of the children at the age 2 reacted positively to PPD.
