Again, Senator Watt, I'm going to insist that, rather than just take the opportunity to say the answer is not appreciated and then read out the question again, particularly when it's only part of the question being read—it contained a number of quotations that refer to a rather comprehensive area of public policy. The minister is directly relevant to that by addressing the issue of vaccination. I can't instruct him on how to answer a question. But I don't think anyone would assert that that is not relevant to the modelling that you refer to.
