My Lords, I cannot promise to have a simple algorithm to make the calculation that the noble Lord refers to. I will ask the system if such a thing exists, but I have never come across such a thing. The challenge he alludes to is entirely right: the vaccine pressure on the virus will create the circumstances in which variants are possible. That is why we are investing heavily in sequencing, not only here in the UK where everyone positive is now sequenced thoroughly and studied, but also offering that around the world through NVAP—the new variant assessment platform—to try to understand what is going on in markets around the world. To date, we think that we have tracked down all the current routes that the virus is taking, and we are satisfied that they are met by the vaccine, but we keep our eyes peeled.

My Lords, evidence shows that those in close contact with a positive case need to be traced with 48 hours to break the chain of transmission. Regardless, if close contacts have to self-isolate or self-test, how does stopping a mandatory requirement to register, either digitally or manually, on entering a venue such as a pub or restaurant help with the effective tracing of close contacts if no record exists of people in venues where positive cases are identified?

My Lords, the registration of people going into events is an onerous responsibility for the hospitality industry and we have to make a proportionate assessment of what kinds of burden we are putting on the economy and society. With more than 60% of the population now having been double vaccinated for over two weeks and with the vaccination programme going along at 500,000 a day, it is the moment to start backing off on some of these obligations. That means dismantling some of the infrastructure of test and trace, which we seek to do in a proportionate and logical fashion.
