I am grateful to my hon. Friend. I seem to be taking multiple interventions today from people I have known in a past life in different ways and forms, which is always a pleasure. He will be aware that the prioritisation and roll-out of vaccines in that context are guided by the clinical advice of the Joint Committee on Vaccination and Immunisation, which, as he will appreciate, at the current time, and rightly, is clearly focused on what will do the most to save lives. We have seen—I will turn to this in my speech shortly—that age is the single biggest determinant of risk of death, so it is right that we are prioritising those most at risk as we roll out the vaccine. When I come to them later, he will hear about the very ambitious and deliverable plans, which he heard about from the vaccines Minister yesterday, to ramp up the roll-out across our country.
