As the Minister said earlier on, the fundamental intentionality here is to support and encourage increased rates of vaccination, because we know that that's an absolute important tool. It does so by doing two things: it allows for vaccine certificates to be used, and I note that more than well over a million people have downloaded that already, so there's clearly appetite and support; and it also allows for greater certainty for businesses about who and how they can operate to safely reopen, which is something everybody is looking forward to.
