COVID-19 Vaccines

Vaccines are safe, effective and the best way to protect you and those around you from serious illnesses like COVID-19.

Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed. This can reduce your risk of developing COVID-19 and make your symptoms milder if you do get it.

Our supply will not arrive all at once, so distribution will happen in stages. The goal is for everyone in Ontario to be able to get a COVID-19 vaccination if they want one, as soon as enough doses are available from manufacturers.

Vaccine safety

Safe and reliable vaccines can help protect you and your family from COVID-19.

They will be an important tool to help stop the spread of the virus and allow individuals, families and workers to safely resume normal life. The coronavirus (COVID-19) vaccine does not cause a coronavirus infection. It helps to build up your immunity to the virus, so your body will fight it off more easily if it affects you.

After independent and thorough scientific reviews for safety, efficacy and quality, Health Canada has approved two vaccines for use in Canada:

Pfizer-BioNTech – approved on December 9, 2020 (PDF)
Moderna – approved on December 23, 2020 (PDF)

Both vaccines are manufactured in Belgium. After two doses, they are expected to be 94-95% effective.

Understanding how COVID-19 vaccines are approved, how they work and possible side effects is important.
