Vaccines - Adults, Healthcare Workers and Older Students

Are your vaccines up-to-date? As a child, you were probably vaccinated against the following diseases: tetanus, diphtheria, pertussis (whooping cough), polio, measles, mumps and rubella. Adult booster doses are required for some of these same vaccines. There are also different recommended vaccines against other diseases that you may be eligible for.


What vaccines do I need?

It is important that you have an assessment by your own health care provider to see which vaccines you may need for post-secondary school, clinical placements, employers and for your age and stage in life. You may have been given a list of requirements, and  you will need to assess your record to see what you have had and may still require.

Getting your Immunization Record

You may have your "yellow card" or immunization record. Check with your health care provider that all doses and dates are complete. If you do not have your record, you can try and access it through the Immunization Connect Ontario website. If you have a valid Ontario Health Card, went to school in Ontario and were born after 1980, there may be a record there of previous vaccines. You will need to obtain your "Immunization ID" first to access this website, by calling 519-663-5317 ext 2452.

*Note: not all vaccines are reported by health care providers, so health unit immunization records may not be complete for those over the age of 18.

*TB skin tests are not included on the electronic record.

Most vaccines, when given at the right time and in the right amount, will give lifelong protection. Sometimes you may need booster shots to continue the protection. If you are asked to get blood tests, they are checking to see if you are immune, or need more doses of certain vaccines.

The diseases that can be tested for by blood tests are: chickenpox, measles, mumps, rubella, and hepatitis B. When you work in certain areas, you may be at higher risk of being exposed to these diseases. Checking to make sure you are immune helps you and your employer know that you are protected.

Please note that the Immunization Clinic at the Middlesex-London Health Unit does NOT provide bloodwork requisitions. You must see your own health care provider or visit a walk-in clinic to have bloodwork ordered.

TB Skin Tests

You may be asked to have a one-step or two-step TB skin test for school, work or volunteering. This helps to assess whether you have been exposed to TB. Please note that this test is NOT available at the Middlesex-London Health Unit unless it is medically necessary for a certain purpose. The Immunization Clinic does not do TB skin tests for any education, volunteer or employer purposes. Ask your health care provider if they can do the test.

Pregnancy and Immunocompromising Conditions

If you are pregnant, or are immunocompromised due to illness or medication, speak to your health care provider prior to any vaccines being given to you.

Immunization Clinic

The immunization clinic at the Middlesex-London Health Unit is available for vaccine administration. Please note that this clinic does not fill out any school or work forms, does not do TB skin tests, and cannot give you bloodwork requisitions.

It is advised that you speak with your own health care provider for vaccines. If coming to the health unit clinic, persons over the age of 18 must live or go to school in London or Middlesex County, and must have an appointment. To speak with a Public Health Nurse, or book an appointment, call 519-663-5317 ext 2330.
