Vaccines - Adults, Healthcare Workers and Older Students

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


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, will need to assess your record to assess what you have had and may still require. Sometimes bloodwork can be done to see if you are already immune to specific diseases, and vaccine doses may not be required.

If you are pregnant, or are immunocompromised due to illness or medicaiton, speak to your health care provider prior to receiving any vaccines.

If you are over the age of 50, pneumococcal and shingles vaccines may be given as well.

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 Ontario database.

  • If you have never lived in London or Middlesex County, you should enter the database through your local public health unit. Call them if your record does not seem to be accessible online.
  • You must have a valid and current Ontario Health Card and postal code to use the system.
  • TB skin tests are not included on the electronic record.
  • Healthcare providers do not provide immunization doses automatically to public health. Therefore, your online record may only contain the vaccines you received when you were in school, and vaccines received afterwards will not be there unless you reported them.
  • if you were born prior to 1980, you may not have a record in the database.


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 (varicella), 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 healthcare provider or visit a walk-in clinic to have bloodwork ordered, and you will need to go back to them to receive your results.

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, identified on paperwork. The Immunization Clinic does not provide TB skin tests for any education, volunteer or employer purposes. Ask your healthcare 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 for adults who do not have a health card or require vaccines for a medical purpose (i.e. stem cell transplant, high-risk HPV or MPox). If an adult does not have a primary health care provider, a walk-in clinic can provide most vaccines required. The health unit can only provide publicly funded vaccines that a person is eligible for.

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 healthcare provider for vaccines as they will have your most recent records. If coming to the health unit clinic, persons over the age of 18 must live or go to school in London or Middlesex County, must have no healthcare provider or health card, and must have an appointment. To speak with a Public Health Nurse, or book an appointment, call 519-663-5317.
