Lords ChamberMy Lords, what a perceptive question from the noble and right reverend Lord—he absolutely hits the nail on the head. The honest truth is that we do not have the precise figures on this but the indications are that he is right: the vaccine does not stop you being infected or transmitting it, but it reduces the chances of both those things dramatically. That is one of the reasons why we have kept our foreign travel arrangements under review. It is possible that the effect that he describes may mean that we can look very thoroughly at foreign travel—I think all noble Lords would welcome that.
My Lords, I have no doubt about the Minister’s personal integrity but he will recognise that he is part of a Government who are not exactly renowned for their probity or truthfulness. I want to ask him about lateral flow tests. There have been reports that the accuracy of this test, which has been less than 100% in any case, is less still when it comes to the delta variant. Can he say a little more about that, and what discussions are taking place with UK companies, who appear to have developed better models which may be more accurate?
My Lords, the noble Lord is entirely right that the Porton Down verification team has looked extremely closely at all lateral flow tests and their sensitivity to the delta variant in particular. There is suggestion and some indication that for very low viral loads, the LFTs are not quite as sensitive, or if they are sensitive, the band is less easy to read. However, for higher viral loads—in other words, the kind of viral loads that the body needs to carry to be infectious—there is no change of sensitivity. Therefore, from that point of view the LFTs continue to perform their original purpose very effectively but we need to keep a very close eye on sensitivity with the new variants.
I pay tribute to all UK companies which are coming forward with LFT, PCR or genomic sequencing tests. I am extremely proud of the progress that the UK diagnostics industry has made. We have extremely high standards and extremely high validation and authorisation protocols through Porton Down. Those standards are very difficult to achieve but we are working extremely closely with UK companies to try to get them over the line so that they can play an important role in our response to the pandemic.
