I refer to a scenario that was not addressed in the written submission. When the virus initially arrived in February, we thought it would last for five or six months. We have had an evolving understanding of it. Mr. Barnes rightly stated that the Government was prudent in preparing the budget on the basis of a no-deal Brexit and a vaccine not arriving until 2022.

The vaccine will arrive sooner than that and we know a little more about the virus. To paraphrase Donald Rumsfeld, there are still a few unknown unknowns. What will the impact be if the virus returns, as the flu does, and requires an annual vaccine? I suppose it is impossible to plan for such a scenario, but it is not out of the question. Do the witnesses have any observations in that regard?
