Covid-19: Brazilian Variant

Lord Patel Excerpts

Tuesday 2nd March 2021 Lords Chamber

[Lord Bethell (Con)]

The vaccine is absolutely central to our strategy. It is an approach that has proved enormously popular, and I think I speak for a large number of people when I say that defending the vaccine has to be our number one priority. If there were a highly transmissible vaccine-escaping mutation, it would take us back to the beginning of this whole pandemic. That is why we have put in place red list countries and managed quarantine. That is why we are committed to Operation Eagle and the efforts to track down those bringing variants of concern into this country.

[Lord Patel (CB) [V]]

My Lords, the scientists are concerned about the P1 Brazilian variant because of three mutations, one of which is common to other variants, making it more transmissible. One of the others is referred to as the “escape mutation”, which may bypass some vaccine-induced immunity. Does the Minister agree that, apart from the measures the Government are taking of trace, track and isolate and surge testing—which I thoroughly approve of—it is important to continue genomic sequencing, at scale, of Covid cases to detect variants that may arise and to monitor and study post-vaccine immune response? That would enable us to modify the vaccines to boost the immune response and deal with the variants.

[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.
