Starting immediately, all Albertans aged 18 and older who received their second COVID-19 vaccine at least five months ago can now book a third dose.

The severity of the Omicron variant is not yet known, but it is clear that there is an increased risk of transmission. Expanded availability of third doses of COVID-19 vaccine will help provide increased protection and prevent community spread.

“There is still a lot that we don’t know about Omicron. But one thing we do know is that the most powerful protection from this highly contagious variant is to get a booster shot. I urge all Albertans to step up and protect themselves and the health-care system with a booster as soon as they can.”

Jason Kenney, Premier   

“I know that many Albertans are eager to get a third dose of COVID-19 vaccine and we are pleased to now offer booster doses to all Albertans aged 18 and older five months after their second dose. Albertans who choose to get a third dose and make use of rapid tests are doing their part to help slow the spread of COVID-19.”

Jason Copping, Minister of Health

“Third doses are especially important to protect against the Omicron variant. Vaccines continue to be our best protection against COVID-19 and with the highly transmissible Omicron variant, I encourage all eligible Albertans to book their first, second and third doses as soon as they are eligible.”

Dr. Deena Hinshaw, chief medical officer of health

Albertans are encouraged to take the first mRNA vaccine available to them for a third dose. Both the Pfizer and Moderna vaccines offer a high level of protection against COVID-19, particularly against severe outcomes.

Pfizer will be offered to Albertans 18 to 29 years of age for booster purposes as a cautionary measure. While there is a slightly increased risk of myocarditis in younger Albertans from Moderna, especially in males, individuals are much more likely to experience myocarditis from COVID-19 infection than the vaccine.

All Albertans aged 18 and older at five months or more from their second dose can book appointments for third doses online with participating pharmacies or AHS by using the Alberta vaccine booking system or by calling AHS at 811.
