I thank my hon. Friend for affording me the opportunity to pay tribute to the work that our armed forces have done across many aspects of this, often visibly but also behind the scenes in providing planning expertise. They have provided in an incredible service to every aspect of the response. This is a massive undertaking—the largest vaccination programme, I think, in the NHS’s history—but, as the deputy chief medical officer has said, plans for it have been under way for some time. That includes logistics, transport and personal protective equipment, but also an expanded workforce so that we can deploy it rapidly. Every part of Government is going to be making a contribution to that, and as soon as the vaccine is approved, we want to be in a position to deliver it to as many people as possible.
