This past spring, we reached out to your organization to seek your support to share information about COVID-19 booster doses with people in Canada. We are writing again as part of our efforts to remind people to stay up to date with COVID-19 vaccinations by getting all doses when they are recommended.

Vaccines reduce the risks of severe illness and death from COVID-19, but protection fades over time. With the return to indoor activities this fall and winter, there may be a greater risk of COVID-19 illness.

That’s why we are reminding people in Canada to get a booster if it’s been:

  • 6 months since their last COVID-19 vaccine dose, or
  • 6 months since they tested positive for COVID-19

Boosters enhance protection, especially against serious disease from COVID-19 infection.

While vaccines may not fully prevent infection or getting sick from COVID-19, vaccination remains one of the most effective ways to protect against serious illness, hospitalization and death from COVID-19, and also help protect our healthcare system. That’s why it’s important for everyone to help strengthen their defences by staying up to date with the COVID-19 vaccines recommended for them.

We encourage people to visit their provincial or territorial website to book an appointment for a booster dose.
