And this bill allows us to do that. It allows us to adapt our public health measures by enabling the Director-General of Health to authorise, by notice, the administration of consented COVID-19 vaccines to be used without, and to be administered without, a prescription. So in that sense, it's, essentially, making a permanent and a bit more of a futureproofed solution to meet those ongoing vaccine requirements. Some of those requirements include, as we're talking about now, additional doses but, also, changes to the dose intervals, perhaps, or targeting different population groups, should that be required, but always and only should the scientific evidence support doing so.
