title: [Test results of purified protein derivative of Bacillus Calmette Guerin of 248 children].
abstract: OBJECTIVE
  To understand Bacillus Calmette Guerin (BCG) vaccination quality, analysis of problems and impact factors so as to promote safe and effective vaccination.
  
  
  METHODS
  248 of the vaccinated children were selected randomly, and to conduct the survey of seroconversion after BCG vaccination for 3 months by Purified Protein Derivative of BCG (BCG-PPD) test method.
  
  
  RESULTS
  BCG-PPD test positive rate was 78.23%; urban children BCG-PPD test positive rate was higher than rural children; the size of BCG-PPD was positively correlated with the test positive rate; BCG-PPD test positive rate of children who administered BCG vaccine in hospital obstetric was higher than that in out-patient children.
  
  
  CONCLUSIONS
  Staff technical training of BCG vaccination, especially in rural areas should be improved. BCG vaccine administered by maternity will improve the timely immunization coverage and quality of vaccination.
