It's a very good question. We're looking to understand the immune implications of the variants. This is a combination of observing the patterns of the variants in the population in terms of the impact they have on transmission and on the disease pattern, but also carrying out more laboratory-based studies that help us to understand how these variants might act differently from the other forms of the virus that we've been looking at thus far.
Everyone in the world is in a similar place on this front. There's an opportunity, not only in Canada but globally, to draw on that scientific enterprise to understand as quickly as possible what the consequences of these variants are for immune protection.
