I thank the First Minister for that answer. I was recently contacted by a constituent who is a student at Swansea University and received a first dose of the vaccine from the Swansea Bay University Health Board, but has come across significant issues trying to arrange the second vaccination elsewhere. If you'll indulge me, I'll read an excerpt of their correspondence, which says, 'I was living in Swansea as a student and got my first dose of the vaccine there. However, when moving back to my home address, I found it extremely difficult to contact Cardiff and Vale health board about the second vaccination. I was pushed from pillar to post and it took me about three or four days of contacting different people where I was continually told that I cannot phone them for my second vaccination, nor could I arrange for my second vaccination to be taken in another health board. It was only through a great deal of persistence and hours spent on the phone that I managed to get this appointment changed, but the system really isn't good enough, and I know that others in my position just won't bother taking the second dose if there is this much hassle involved'. So, can I ask, First Minister, what action are you taking to ensure that the process of booking a second vaccination in a different health board to the first is made as easy as possible for those, like students, who live in different places at different times of the year?
