Adverse Events Following Immunization

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.

In Ontario, health care providers are legally required to report AEFIs to their local public health units. Public health units investigate AEFIs and provide support to immunizers, individuals, and their families.

Fax an AEFI reporting form to HPE Public Health at 613-966-8145.

South East Health Unit (formerly Hastings Prince Edward Public Health) is situated and provides services on the traditional territory of the Anishinaabe, Huron-Wendat and Haudenosaunee people.

SOUTH EAST HEALTH UNIT

As of Jan. 1, 2025 Hastings Prince Edward Public Health; Kingston, Frontenac and Lennox & Addington Public Health; and the Leeds, Grenville and Lanark District Health Unit have merged to form the South East Health Unit.

Partners and members of the public should continue to engage with their local public health offices as usual until otherwise directed.

Efforts are underway to develop branding for the South East Health Unit, which will take several months. In the meantime, you will see logos and other advertising material with Hastings Prince Edward Public Health branding. You may also see some documents using the legal name South East Health Unit.
