Information for Health Professionals


The Grey Bruce Health Unit plays a vital role in promoting immunization in our communities. The Health Unit distributes publicly funded vaccines to community partners, assesses the immunization records of students enrolled in elementary or secondary school and children enrolled in daycare, and provides immunization information to doctors and other health care providers, as well as to parents, schools, and the general public.


Reporting Adverse Events Following Immunization

It is important for patients to know that some common mild reactions may occur following immunization. Common mild reactions to vaccine(s) may include redness, itching and/or rash at the injection site and less commonly, headache, dizziness and nausea may occur. Severe allergic reactions are very rare, however patients should be advised to seek medical attention immediately if they develop any of the following symptoms within 3 days of getting the needle: hives, swelling of the mouth and throat, trouble breathing, hoarseness or wheezing, high fever (over 40⁰C/104⁰F), convulsions or seizures, or any other serious reaction to the vaccine.

All “reactions” to an immunization that meet one of the Provincial Case Definitions for an Adverse Event Following Immunization should be reported to your local Public Health Unit. These reports are used to ensure the continued safety of vaccines on the Canadian Market.
