Covid-19: Brazilian Variant

Lord Winston Excerpts

Tuesday 2nd March 2021 Lords Chamber

[Lord Bethell (Con)]

The noble Lord is entirely right. Our commitment to genomic sequencing, which has lasted for years, has put Britain in great shape to be able to do the sequencing necessary to track these variants. We are doing more sequencing than any other country. But as the noble Lord knows, this is detective work, and it is extremely complex. While the 484K mutation might be the significant change in both the Brazil and South African variants, it might be one of a great many other mutations in its genomic characteristics. This is the detective work we are doing. I am afraid that it will take some time to get to the bottom of it, and it needs to be complemented by field studies into how the mutation reacts in real life, as well as with antibodies. The combination of immunology, virology, biology and real-world clinical study will give us the insight that we need.

[Lord Winston (Lab) [V]]

My Lords, with due respect to the Minister, I wonder if a pinch of salt is quite the right treatment for some of these variants of the Covid virus. It is not just the Brazilian and other different variants. For example, in addition to Siqueira’s paper, which has just been published from Brazil in the last couple of weeks, the paper from Bogota shows numerous variants which are not quite the same. Some of these may be rather more virulent, and it is possible that they may even cause reinfection—it is certainly not very clear. The point is this: surely we need to be very cautious indeed about our airports and whether the list we have is sufficient. At what stage do we decide that we need to take much firmer action with all incoming passengers to the United Kingdom, making certain that they are properly tracked and traced?

[Lord Bethell (Con)]

The noble Lord is entirely right. Things are happening around the world which are causing a great deal of anxiety. Stories of possible reinfection in South Africa are extremely concerning and the huge spike in infections in South America has not been properly explained. It is possible that there are a number of mutations, and mutations of mutations, there. The truth is that we do not have the genomic or immunological data that we need to fully understand what is going on. That is why we have taken a precautionary approach, as the noble Lord recommends. We have instituted both managed quarantine and a red list which we keep under review. If we feel it necessary to extend that list, we will do so.
