The vaccines are given by injection as a series of two doses. It is important to get both doses of the vaccine for full protection. Second doses will be offered 16 weeks from the first dose based on provincial and national recommendations, including for those who have already received their first dose. Data from jurisdictions around the world shows one dose of vaccine provides a high level of protection. When it’s time to receive your second dose, you will be invited to receive it just as you were for your first. Please retain your paper record of immunization to bring back to the clinic with you at that time.
