Thank you for that response. No one, of course, would deny the challenges arising from the circumstances in which the vaccine has to be stored. My second question also refers to that distribution challenge; it's on ensuring that there is equal opportunity for people, wherever they are in Wales, to have the vaccination. It's been suggested to me in briefings from officials that this vaccine isn't the most appropriate, perhaps, for harder-to-reach areas—rural areas, for example. But, of course, we only have this one that's been approved at the moment. So, can we have an assurance that people will be treated equitably in terms of being able to access the vaccine, if they are in the particular target group, whether they're in Wrexham or Risca or Aberdaron or Aberdare?
