I am grateful to the noble Baroness for giving me an opportunity to address this issue, and I hope the noble Baroness, Lady Thornton, will forgive me for overlooking it in my opening answers. The noble Baroness, Lady Bennett, is entirely right: ventilation is critical—but it is also challenging. On air filters, we have to understand better the science of whether filtration really makes an impact on the spread of the virus. I would not want investment in a large amount of ventilation infrastructure that did not actually have an impact. I agree that we have a lot to learn from the Victorians, who understood these matters very well. We must understand how modern buildings, which are often airtight to achieve environmental qualifications, may need to be adapted to get fresh air within them. We may also need to change our lifestyles, so that more socialising, eating and drinking is done outside—something that I, as an outdoorsy person, would very much welcome.

I am sure that the Minister is alive to the fact that the beta variant is less susceptible to the AstraZeneca vaccine in particular, with effectiveness as low as 10%. Perhaps, therefore, he found it understandable that the Government put further restrictions on travel from France. However, could he explain why we are not doing it with Greece, where the levels of that variant are higher than in France, or Spain, where they are much higher than in France?

The noble Lord makes an important and serious point—but could I just address one matter first? The AstraZeneca vaccine has very low efficacy on a single dose against beta—around 14% or 15%—but on two doses its effectiveness is significantly higher. None the less, his broad point is right. As we vaccinate the nation, the variants that escape the vaccine will gain a natural advantage, and those will be the ones that begin to outperform the highly infectious variants such as delta that work so well among the unvaccinated. When it comes to travel, the analysis is complex. We have taken a precautionary approach with France, which I think is right, because there is a large amount of beta in France, but we are looking at all countries all the time, and we will take whatever steps are necessary to protect these shores.
