Tuberculin reaction and BCG scar in children vaccinated at birth
AbstractIn this study, 1576 healthy children under 6 years who had received BCG at birth were tuberculin tested. About 71.5% had retained their BCG scar. The average size of tuberculin reactivity was larger in the group with BCG scar than without, the difference being statistically significant [P < 0.05]. The relative frequency of children showing a negative reaction increased with age; at 4 years about 68% of vaccinated children were negative. There was a positive linear relation between the size of BCG scar and diameter of tuberculin reactivity. After 4 years, tuberculosis infection should be suspected with a positive tuberculin test, especially if the reaction size is >10 mm
