Senator CHISHOLM (Queensland) (15:00): Lincoln Hopper, CEO of St Vincent's Care Services, has said that the mistake has 'caused us to question whether some of the clinicians given the job of administering the vaccine have received the appropriate training'. Why has the government neglected to ensure proper training in the rollout of the vaccine? Honourable senators interjecting— The PRESIDENT: Order! We will get to this last answer when there is some modicum of order across the chamber. Government senators interjecting— The PRESIDENT: Order, Senator Canavan, Senator Ayres, Senator McKenzie and Senator Rennick. I call Senator Colbeck to answer the question.
