I would just reiterate that it's very important to get two doses to maximize protection. I think provinces are at the moment going back to vaccinate the initial high-risk groups, so you'll see that happening. Many of the long-term care facilities have already had two doses.
From a supply perspective, given that age group and the amount of vaccine needed in the younger age group, what I've been told is that you can actually do both. Because of so many vaccines arriving, you can do both simultaneously.
