So what did we learn about supply chains from last year around measles vaccines and influenza vaccines? Were we ready? Had we figured out that no matter that it may be in central stores; it's not getting out to regional areas? Now, I know there have been some changes made, and I think they're actually correct—that is, to take PPE out of the hands of regional DHBs and centralise them. We maybe could have learnt that, or maybe we were doing that and it wasn't effective—I don't know. The Minister can address that, but maybe we should've brought those smarts to the table a heck of a lot earlier than we did. So I think this was a learning that we clearly had out of infectious disease last year, that DHBs were telling us that we should have been ready to do. We should have had the supply chain of PPE. If we ever get a vaccine, please, goodness, let us have a supply chain that makes sense and can deal to that. I've put that question on the table: supply chain and were we ready; did we learn from infectious diseases last year?
