Thanks to Russell George for that question. As I said in my original answer, the spring booster campaign in Wales began last week, on 14 March, focusing on care home residents in the first instance. We expect, within a further three weeks, to have completed the bulk of care home vaccination. There will be some care homes, because of outbreaks, where there will be some further time needed, but the bulk of care home residents will have received that booster. And then we will continue with the rest of the population. It depends, as I know the Member is aware, on when you had your last vaccination when you get called, because a certain number of weeks have to elapse before it is safe and sensible for you to have the fourth vaccination. We will use all the normal means of communication—directly from health boards, using the Welsh Government's own social media channels, in which the leader of the opposition has shown considerable interest in recent times. We will be using those to make sure that we get that message across, and the key message in Wales is that you will be contacted by the health service; it doesn't rely on you going hunting for an appointment. The health service will come to you, and it will do it, as we've seen through the whole pandemic, very reliably and at the right moment for you.
