"Provincial reporting of AEFIs is an important component of the overall safety assessment of any vaccine. This type of surveillance, commonly called post-marketing or post-licensure surveillance, allows for monitoring of the vaccines throughout implementation in the context of “scaled up” vaccine production and expansion of the population receiving the vaccine.

Individual case reports of AEFIs represent an important source of data as they have the potential to generate signals of adverse reactions not previously recognized in clinical studies which can be further evaluated.1 This is particularly important for rare adverse events which may not have been evident in clinical trials due to limited sample size.

In Ontario, reporting of AEFIs by specific health professionals is mandated under Section 38 of the Health Protection and Promotion Act (HPPA)". - Appendix B: Provincial Case Definitions for Reportable Diseases
