Participating pharmacies and Alberta Health Services will begin booking appointments for AstraZeneca vaccinations for Albertans born in 1981 or earlier. Walk-in vaccinations will be available at the walk-in clinics in Edmonton and Calgary, as well as specific pharmacies across the province. Lowering the eligibility age means 575,425 more Albertans can be vaccinated, bringing the total eligible population to 2.3 million. “With COVID-19 cases at high levels throughout the province, we are lowering the age eligibility for this vaccine so that as many Albertans as possible are able to choose the protection this vaccine offers. The more people that get vaccinated as quickly as possible, the sooner we can protect our communities, reduce the burden on our healthcare system, and get life back to normal in our province.”
