Your Immunization Record (Yellow Card)

An immunization record, or yellow card, keeps track of all immunizations, or vaccinations, that you or your child has received. It is important to make sure that this record is kept up-to-date and stored in a safe place with your other important documents.

Personal immunization records may be required for school, work or travel. An up-to-date immunization record will prevent unnecessary extra shots.

Does the Health Unit have a record of all immunizations?

The Health Unit has a record of all immunizations given by the Health Unit's nursing staff. 

It is important to know your health care provider does not automatically inform the Health Unit when you are given a vaccine.  It is the responsibility of an individual, or a parent/guardian, to let the Health Unit know of any immunizations received from a health care provider.



How can I let the Health Unit know if I have received an immunization from another health care provider?

If you get a vaccine from another health care provider, including a health unit in another part of Ontario or another province, please let us know so our records for you are as up-to-date as possible. You can:

  • Use a safe and secure website;
  • Fax to (807) 625-4828
  • Mail to Thunder Bay District Health Unit,  Immunization Department 999 Balmoral Street, Thunder Bay, ON  P7B 6E7
  • Phone (807) 625-5900 or 1-888-294-6630.
