You’ve heard the word booster get talked about a lot lately and are probably wondering what it all means. You got vaccinated, so why are you being asked to go get another dose? What is a booster dose exactly, and why should you be getting one?
What is a COVID-19 booster dose and why do I need it?
Over time the protection your body receives from your original dose(s) naturally starts to decrease. This means if you were to get COVID-19, your body would not be able to protect itself as well. This makes you more at risk for severe outcomes such as hospitalization and death. A booster dose helps bring your body’s level of protection back up.
I’ve already gotten COVID-19. Do I still need a booster dose?
Yes. While getting COVID-19 does provide you with some protection afterwards, research continues to show that getting a booster dose after you get COVID-19 results in your body responding better against future infection while also providing longer-lasting protection.
If you have had COVID-19, it is now recommended to get your booster dose three months after your symptoms first started, or you had a positive test.
Who should get a booster dose?
Anyone 12 years or older. The chart below tells you when you can get your booster dose, according to your age.
Can my booster dose be a different brand than I got before?
Yes. Health Canada has approved two vaccine boosters, Pfizer BioNTech and Moderna. Research shows that both vaccines are safe, effective and can be substituted.
If you are 30+ years old, the best vaccine is the one available to you right now.
If you are 12-29 years old, Health Canada recommends you get the Pfizer BioNTech vaccine as it can help reduce the rare risk of myocarditis or pericarditis in this age group.
