Llywydd, can I thank Adam Price for those important questions? I think his description of it as a glimmer of hope is a good one, because I think that is what it is. It is hopeful and we need a bit of hope in these difficult times, but we mustn't exaggerate it either. It is the chief medical officer's office in Wales that is in charge of planning for any vaccine that becomes available to us. The chief medical officer was involved in this as far back as June, and was in correspondence with our health boards in July to make sure that plans are in place. 

On the storage issue, Llywydd, I think our current expectation is that if it were to be the Pfizer vaccine that was available first, with its need to be stored at below -75 degrees centigrade, then we would use the facilities available to the Welsh Blood Service, which does have facilities and in different parts of Wales that are able to keep things refrigerated at that temperature. But there are complications. My understanding of this vaccine is that it can only be taken out of refrigeration on four occasions before it's no longer capable of being used. So, there are some very real constraints with it. It has to be administered twice, as I know the Member will know, at a three-week interval, and it doesn't become effective until the first week after the second dose of the vaccine has been delivered. So, there's another set of difficult complications there. We don't yet know as to whether or not it will be effective in older people, and that's particularly a challenge at the moment because the Welsh plan, which is very similar to plans elsewhere in the United Kingdom, is to begin with priority groups and to begin with priority staff who are capable of administering the vaccine. So, our plan is that we would start with experienced vaccinators, people who do this all the time, and then we would expand beyond that. So, that's in terms of delivering the vaccine.

In terms of who will get the vaccine, until we're certain—more certain than we are now—as to which groups in the population this particular vaccine will be effective for, then we're likely to start with healthcare staff, social care staff, to make sure that front-line workers who are regularly in contact with people with coronavirus are vaccinated, and then, if it is effective with older people, then it will be care home residents and people in later stages of life that will get the next priority. So, it's a priority system; it will depend on how quickly the vaccine becomes available. We'll get a population share of it here in Wales, but there are a lot of questions that we will not yet know the answers to, and as those answers emerge, we will be able to firm up the programme that we will have for delivering the vaccine to those who need it the most first.
