AEFIs are unexpected or unwanted medical occurrences that happen after someone has received a vaccine. Health authorities closely monitor AEFIs as part of vaccine safety monitoring programs to ensure the safety of vaccines and to detect any potential safety concerns.
To report COVID-19 vaccine AEFIs, see the following BCCDC resource page: COVID-19 Vaccine Adverse Events Following Immunization (AEFIs).
To report influenza vaccine (and other vaccine) AEFIs, see BCCDC resource page: Adverse Events Following Immunization (AEFI).
