Assessment of the need for universal BCG vaccination of children in Taipei

The findings indicate that one of the criteria established by the International Union against Tuberculosis and Lung Disease to discontinue universal BCG vaccination has been met in Taipei. Despite this favourable condition, considering that the sputum-smear-positive rates were as high as 20.11 per 100,000 population, universal BCG vaccination should be retained until the risk of exposure decreases.
