Vaccine Brighton Collaboration Causality Assessment

The Vaccine Brighton Collaboration Causality Assessment tool provides a systematic method to evaluate adverse events following immunization (AEFI). It begins by assessing whether the event is causally associated with the immunization. If not, it identifies other strong evidence for alternative causes. The MTTI tool further classifies events based on evidence as consistent, inconsistent, unlikely, or unclassifiable, ensuring a clear understanding of causation. Designed for accuracy and reliability, this tool aids healthcare professionals in evaluating vaccine safety, ensuring evidence-based decisions, and maintaining public confidence in immunization programs by addressing adverse events comprehensively and systematically.
