I was in isolation last week, so I haven't had a chance to sit on the committee, but I'm aware that the committee has done a good job very quickly getting to grips with the issues behind the legislation. I think a couple of points come out at me. The first is that a fourth dose is going to be useful for some people—probably not everyone, and it will be voluntary—and I'm already getting emails from a few people who are saying they're really keen to go and get a fourth dose. I'd encourage those who are eligible and who would find it helpful to go and do that at the appropriate time, which is not too far away. I think the science is relatively clear.
