【Abstract】 In order to make clear the immunization and infecation situation of tuberculosis while stopping BCG booster vaccination, 20,107 children under 13 years old in Shandong Province were chosen randomly to investigate by PPD test in 1998. The results showed that the average positive rate and intense positive rate of PPD test were 35.71% and 7.66%. There were significant differences for PPD test positive rates between different districts and different age groups, and there was positive correlation of the positive rate with the BCG immunization doses, BCG vaccinated scar, vaccinating technique and tuberculosis contact.
