Frequently Asked Questions about the COVID-19 Vaccine

General information

If you're getting vaccinated soon

  • If I tested positive for COVID-19 in the past, should I still get the vaccine?

    If you had COVID-19 in the past, you're likely to have some immunity. Immunity to COVID-19 is still being studied, but is generally strong within 90 days of infection and can reduce over time. Where supply is available, people with past illness in the last 90 days are still recommended for vaccination since vaccine might provide better immunity than natural infection.

  • What do I need to know about the second dose?

    It's important for individuals to ask the health care professional performing the first dose of their COVID-19 vaccination when to expect their second dose.

    If your second dose vaccination appointment was cancelled, you will be notified about a second dose that will be given within the acceptable interval. For more information, contact the home where you received your first dose.

  • If I had a reaction to a different vaccine in the past, can I still get the COVID-19 vaccine?

    Most people who had a reaction to a prior vaccine can safely receive the COVID-19 vaccine. Check with your doctor or health care provider if you have had a serious allergic reaction to a vaccine in the past. They will look at your medical records and advise you accordingly.

  • Is it acceptable for someone with food or seasonal allergies to receive the COVID-19 vaccine?

    Yes. If you have allergies that are not related to any components of the COVID-19 vaccine, you can still be vaccinated.

  • Who should not get the vaccine?

    People who have had a serious allergic reaction, such as anaphylaxis, to a component of the COVID-19 vaccine cannot receive the vaccine. For the current COVID-19 vaccine, if you have an allergy to polyethylene glycol, you should not get vaccinated if your past reaction was severe. Others who have had a less serious, but immediate allergic reaction, should see their health care provider for guidance.

  • Who should consult with their health care provider about getting vaccinated?

    There are other groups where the vaccine has not been studied enough to be completely certain about its safety, but based on general scientific knowledge and experience with previous vaccines there are no reasons to think it would be unsafe.

    • Pregnant women or those trying to get pregnant
    • People who are breastfeeding
    • People with compromised immune systems or autoimmune diseases

    We would generally recommend vaccination for people in the above groups with a high-risk of exposure to COVID-19, such as those working in long-term care and retirement homes. However, the potential risks and benefits should be discussed with your doctor or another healthcare provider.
