And I'd be interested to hear any discussions around whether we've considered the merits or otherwise of futureproofing this bill, both for other coronavirus vaccines that may be required or, indeed, to make it clear that the routine flu vaccine is covered by this. I do understand that the Therapeutic Products Bill will fix all of these issues and this redundancy, but that's going to take a lot of time. If we do need to move quickly, if we do run out of Pfizer vaccine and do end up moving to AstraZeneca or an alternative, again, I come back to that point: are we coming back to the House?
