My hon. Friend makes an important point about vaccination roll-out. We have also been doing testing pilots around the country to see how we can be in the best possible position so that, if a child does have covid, it does not mean that a large group of children will have to self-isolate. As we complete those pilots, we will look at how we can roll that out, especially into the areas that have been most affected. He makes an important point on vaccination, and we are certainly looking at how we can prioritise that, since teachers and support staff play such an important role in our national endeavour.
