Minister, the vaccine roll-out is proceeding very effectively and efficiently, which we're all very grateful for, but, obviously, we need a very good take-up of the vaccine if we are going to have Wales as protected as we would like it to be. It is good, generally, but there are some gaps, and you've referred already to black and ethnic minorities, for example. I know there's emerging information in terms of some our more deprived communities not taking up the vaccine opportunities in the numbers that we would like. You've already talked about role models, Minister, and communication and messaging. As this information becomes available, in terms of gaps in vaccine take-up, how will you be monitoring that and responding to it, in terms of adapting messaging and communication, and working with those who reach out into these communities and can help to improve the position as we go through this programme?
