Australia is currently suffering from an appalling flu outbreak, which is worse than any it has seen in many years. The vaccine for under-65s is more complex this year and will not be in place before 31 October. Does the right hon. and learned Gentleman agree that if we have a worse epidemic than in 2017 and do not have the vaccines, which have to be kept chilled, we could grind NHS services across the UK to a halt this year? If we do not have the details from Yellowhammer, how can anybody be prepared?
