[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.

Method: 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.

Result: 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.

Conclusion: 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.
