The document discusses using an ontology to standardize adverse event reporting. It proposes defining adverse events following immunization (AEFIs) using standard definitions from guidelines like Brighton Collaboration to ensure unambiguous meaning. An ontology would allow computer-based querying and validation of reported events. Early work includes modeling seizures and collaborating to implement the ontology in reporting systems. This will improve data quality, consistency and enable complex queries.
