Minister, the roll-out of a vaccine within days, as we're told, is obviously going to be very significant in terms of controlling the virus in the hospital environment. One of the aspects of this particular vaccine is that it has to be kept at -70 degrees centigrade, which means that managing it and containing the vaccine is going to be an extremely difficult technical task. Is it likely that vaccination in hospitals is going to be one of the high priorities when it is possible to roll-out the vaccine within Wales? Can you give us any more information on this?
