For health professionals
How to report an AEFI:
Monitoring and communicating about vaccine safety is essential to the success of immunization programs. We support Ontario’s immunization stakeholders to better understand and communicate about vaccine safety. Public Health Ontario also leads the provincial surveillance of adverse events following immunization (AEFIs). We monitor and evaluate vaccine safety and contribute to national and international surveillance systems.
In Ontario, health professionals are required to report AEFIs to their local public health unit. Public health units investigate AEFIs and provide support to immunizers, individuals and their families. An 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.
Public Health Ontario is a member of Vaccine Safety Net – a global network of websites, evaluated by the World Health Organization, that provides reliable information on vaccine safety.
