An adverse event following immunization (AEFI) is an unwanted or unexpected health effect that happens after someone receives a vaccine, which may or may not be caused by the vaccine. Health care providers (i.e., physicians, nurses and pharmacists) are required by law to report AEFIs.
Reports of adverse reactions occurring in the Thunder Bay District should be made using the Ontario AEFI Reporting Form (PDF) (note: this document has shown to be difficult opening in Firefox and potentially other browsers.
