Now, one of the issues that we've been canvassing in the discussions between the parties in advance of this legislation coming before the Parliament is whether or not what's called an immediate modification order pursuant to the epidemic preparedness response Act should be essentially used to give effect to the fourth dose being widely available. And it's been pointed out by people that the Immediate Modification Order (IMO) process, as it's known, has, for example, changed the time frames for the third dose from six down to four and then three months. The question is really: should that be able to be used for the provision of the fourth dose? For my part, I think that is an open legal question.
