To describe adverse event following immunization or vaccination in children in Minas Gerais: 2015 to 2020, resulting from immunization errors in children from zero to nine years old. An ecological, descriptive study with a quantitative approach, based on event notifications available in the National Immunization Program Information System. Among the 39,903,277 doses of immunobiologicals in children aged zero to nine, administered in the state of MG, 3,259 events of types of immunization errors were recorded, around 0.008% of the total and, of these, 91.86% did not result in adverse events and 56.02% were children under one year of age. The most frequent diagnosis was application outside the recommended age (29.12%). Among the manifestations, 71.91% were local and systemic, with fever being the most common (40.85%). The study demonstrated that immunization errors were rare and that most of them were not associated with adverse events, which reinforces the safety of the immunization process. This undoubtedly raises reflection on the need and relevance of continuing education for health professionals.
