Thank you, Llywydd. This morning there's been a suggestion that the Joint Committee on Vaccination and Immunisation could recommend changes to the priority groups for vaccination if evidence, which is starting to emerge, demonstrates that vaccination has an impact on the transfer of the virus too—not only does it prevent people from becoming ill, but it protects those around them too. I know that following the advice of the JCVI is the Welsh Government's policy, but can the Minister tell us how willing the Government is to change strategy, if necessary, in terms of the necessary digital infrastructure and so on? Can the Government implement a new policy at short notice if that is the advice the Government receives?
