I don't think I can be any clearer about the actual position—that the vaccine isn't being held back, it's being delivered to our NHS as quickly as the NHS can deliver itself, and our infrastructure has increased significantly to allow even more of those supplies to go out, and we'll carry on doing so. And I should say that we're in the same position as other UK nations in having a store of the Pfizer-BioNTech vaccine that is being stored in significant storage facilities to then be delivered as quickly as all nations can have it. So, the Pfizer vaccine delivered today in England, Scotland and Northern Ireland is from a delivery they will already have had, just as it is here in Wales, and it's about the capacity of each of our delivery systems to be able to deliver that into the arms of the public. And I look forward to figures for the end of this week to see the significant increase that I fully expect in the delivery both of the Pfizer-BioNTech vaccine and the AstraZeneca one, and I look forward to people across the Chamber welcoming and celebrating the success of our NHS in doing so.
