Thank you very much, and thank you for that response. We had an opportunity at health committee this morning to question members of the technical advisory cell on the next steps, but I wonder if you could tell us a little more, Minister, as to when the opportunities provided by the vaccine will be included in modelling for the likely pattern of the pandemic over coming months. This is only a development, of course. We're very pleased to hear of it, but we're a very long way from being in a situation where a vaccine will be available to be administered to people. But to date, of course, we don't know what the expected impact of the introduction of a vaccine will be on the spread of the virus in months to come. So, I wonder if there's any modelling on that, and more assurances, perhaps, if you could provide them, on the guarantee that Wales will receive at least its population share as the vaccine is distributed, whenever that may be?
