DAVID SEYMOUR (Leader—ACT): Thank you, Mr Chair. I just wanted to ask the Minister about how he interprets the legislation before us. It says that if the Minister has given consent or provisional consent to a COVID-19 vaccine and a data sheet is approved for the vaccine under the regulations, the director-general (DG) can authorise a different way of administering it. In other words, that would mean that a vaccine that's already being used for COVID—and I assume that would include several, and I wonder if he could tell us which ones—the way it's administered, the doses, the frequency, perhaps even how it's injected, could be changed. Could he just confirm that is really what this is about. It's not about new vaccines; it's about the administration of those that have been consented, and, if so, which ones will it apply to that are currently consented COVID-19 vaccines?
