The virus is always undergoing evolution, and we're monitoring this not just in Canada but around the world. There is a distinct possibility for other variants to occur, although the virus seems to be homing in on a couple of very key mutations that are common to a number of these variants, so we might be seeing the virus settling down on some of those mutations. We just have to keep track, and we are doing all the mutation analysis, the screening and the genomics analysis. We may have to modify the vaccines accordingly. We will have to see about that.
