In Ontario, health professionals are required to report adverse events following immunization (AEFIs) to their local public health unit. Public health units investigate adverse events and provide support to immunizers, individuals and their families. Public Health Ontario analyzes AEFIs that are reported in Ontario to monitor the safety of administered vaccines and contribute to national and international vaccine safety surveillance systems.
An adverse event following immunization is an unwanted or unexpected health effect that happens after someone receives a vaccine,which may or may not be caused by the vaccine. If you have an AEFI, contact your health care provider.
The Annual Report on Vaccine Safety in Ontario, 2014 is a comprehensive annual provincial assessment of vaccine safety, and includes a summary of adverse events following immunization (AEFI) reported in Ontario in 2014.
