Bivalent Booster Rollout to Begin for Those 18+

Government of Alberta

Starting on Sept. 21, appointments for the bivalent COVID-19 booster vaccine can be booked, with vaccine administration also beginning on Sept. 21.

After a thorough and independent scientific review, Health Canada approved the Moderna Spikevax Bivalent COVID-19 vaccine as a booster dose for eligible Albertans 18 years and older.

The bivalent COVID-19 vaccine triggers a stronger immune response and provides additional protection against both Omicron and the original SARS-CoV-2 virus strain.

Albertans who have completed a primary series are eligible for the bivalent vaccine. The recommended interval between doses is a minimum of five months from the last dose or previous infection.

A shortened interval of three months can be considered (for individuals at higher risk for severe outcomes, for example), but a longer interval between doses leads to a better immune response against COVID-19 infection that is expected to last longer.
