Bacillus Calmette-Guerin (BCG) vaccine safety surveillance in the Korea Adverse Event Reporting System using the tree-based scan statistic and conventional disproportionality-based algorithms

摘要

Background: Substantial variations in the safety profiles of different formulations of the bacillus Calmette-Guerin (BCG) vaccine exist. Therefore, we aimed to detect safety signals of BCG vaccine for intradermal injection (BCG-ID) and percutaneous injection (BCG-PC) in the Korea Adverse Event Reporting System (KAERS).
