All current Health Canada approved COVID-19 vaccines are administered in a two-dose immunization schedule.
COVID-19 vaccines are provided to Albertans in a 16-week (4-month) timeline between the first dose and second dose, based on the current National Advisory Committee on Immunization (NACI) recommendations.
Emerging evidence shows that the first dose of COVID-19 vaccines provides protection to recipients in Canada. Therefore, NACI recommends maximizing the number of individuals receiving the first dose by extending the second dose up to four months after the first, because
- COVID-19 vaccine supply is limited, and
- the COVID-10 pandemic is still not yet over.
In other words, the priority at the moment is to first vaccinate as many people as possible by giving them the first dose.
NACI will continue to monitor the evidence and update this interval as needed.
All eligible Albertans can book their first dose only. They will receive a reminder from Alberta Health Services (AHS) at a later date, by text message, email or automated call, of when to book for their second dose.
