With the arrival of the Omicron variant, and increased booster eligibility for all Albertans aged 18 and older, vaccine demand has surged. Since Dec. 7, more than 1.2 million third doses have been administered.

Jason Copping, Minister of Health, said vaccines continue to be an important part of the province's efforts to prevent hospitals and ICUs from being overwhelmed with new cases of COVID-19. "It is critical every Albertan continues to get each dose they are eligible for," he said.

AHS says based on current evidence, it appears vaccine effectiveness against COVID-19 infection wanes over time, particularly with the Omicron variant. Individual protection against severe outcomes remains strong after two doses for most, however, a third dose strengthens protection against both infection and severe outcomes.

Everyone 18 years and older can book appointments for a booster dose of mRNA vaccine at least five months after receiving their second dose. Albertans 12 years and older who are immunocompromised can also book an appointment for a booster but must wait at least eight weeks after their second dose.

Those wanting the vaccine can call 811, participating pharmacies, or the Alberta vaccine booking system.
