Two of the vaccines approved for use in Canada are viral vector-based vaccines: AstraZeneca and Janssen. These types of vaccines use a harmless virus (in this case, the adenovirus) as a delivery system. This vector virus is not the virus that causes COVID-19. You can't get COVID-19 from the vaccine itself.
