Abstract

Marked fluctuations in sensitivity to tuberculin related to the time of nonspecific vaccinations were found in children aged 1 to 7 years vaccinated with BCG within the first week of life in annual Mantoux test (2 tuberculin units). At the age of 3 and 7 years vaccinations raise sensitivity to tuberculin causing a rise in positive reactions to tuberculin. This indicates changes in postvaccination allergy to BCG.
