Frequently Asked Questions

What is a third dose of the COVID-19 vaccine?

A third dose is an additional COVID-19 vaccination that helps you maintain and lengthen your protection against the virus. With this strengthened protection, you are helping protect yourself and the people around you from the spread of COVID-19.

What is the current evidence supporting the third dose?

Even though two doses provide strong protection against infection and severe illness, there is now evidence that shows that getting a third dose will help you keep up your full level of protection against COVID-19. This is of particular importance given the presence of the Omicron variant, which is more infectious than prior COVID-19 variants.

Recent data from Ontario indicates that vaccine efficacy against symptomatic illness six months post-vaccination decreases to approximately 81%, as compared to 95% initial efficacy following a second dose. For eligible populations, the third dose of the COVID-19 vaccine re-establishes vaccine efficacy against symptomatic illness. For certain groups, this also reduces the rate of severe outcomes, such as hospitalization and death.

Do I need to get a third dose?

Given recent evidence regarding vaccine efficacy in the context of the Omicron variant, we strongly encourage all individuals who are eligible to receive a third dose of vaccine to preserve efficacy against COVID-19 disease.

Is it recommended to receive the same vaccine brand as you did for your first or second dose?

Individuals who received two doses of an mRNA Vaccine (Pfizer-BioNTech or Moderna) or two doses of the AstraZeneca vaccine may receive the third dose with either mRNA vaccine product.

If you had Pfizer or Moderna for your first or second dose, it is safe and effective to have either mRNA vaccine for your third dose. COVID-19 mRNA vaccines help your body make antibodies that protect you from getting sick if you are exposed to the COVID-19 virus. Both the Pfizer and the Moderna vaccine are around 95 percent effective at protecting you from experiencing a severe case and hospitalization if you were to get sick with COVID-19.

The possible side effects for both mRNA vaccines are also very similar. Common side effects include tiredness, headache, muscle pain, fever and nausea. These are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in two to three days. Some people have no side effects.

Serious reactions are rare. If this does happen, it usually happens within minutes. If you are concerned about the vaccine and potential side effects, speak with your primary care provider.

I misplaced my proof of vaccination. What should I do?

If you have misplaced your proof of vaccination, you can easily retrieve it by visiting covid19.ontariohealth.ca and following the step-by-step instructions to download your confirmation receipt. This website works with most modern browsers on desktop and mobile devices.

If you do not have a valid health card, please call the Provincial Vaccine Booking Line at 1-833-943-3900. This line is available 8 a.m. to 8 p.m., 7 days a week.

How do I know that the COVID-19 vaccine is safe?

Health Canada has approved four vaccines after thorough scientific reviews for safety, efficacy and quality based on large, high-quality clinical trials:

  • Pfizer-BioNTech – approved on December 9, 2020
  • Moderna – approved on December 23, 2020
  • AstraZeneca – approved on February 26, 2021
  • Johnson & Johnson – approved on March 5, 2021

These vaccines have met all the requirements for approval, including safety. They continue to be monitored for any adverse reactions that may occur after vaccination and appropriate measures will be taken, which is consistent with current practice for all new vaccines and drugs.

If I get vaccinated, can I stop following COVID-19 public health measures?

Although vaccination provides protection against symptomatic COVID-19 infection, everyone – vaccinated or not – must continue to follow all public health measures, including wearing a mask, maintaining physical distance and practicing proper hand hygiene.

What are the potential side effects of the vaccine?

Most people who receive vaccines have minimal or no side effects, although, as with any medicine, adverse reactions can occur. The most common side effects are injection site pain, swelling, redness; headache; stomach and digestive complaints (e.g. nausea, vomiting, diarrhea and/or stomach pain); muscle or joint pain; tiredness; headache and chills/fever.

Serious reactions are rare. If this does happen, it usually happens within minutes. If you are concerned about the vaccine and potential side effects, speak with your primary care provider.
