Genome sequencing is a way to tell if there are mutations in the virus. This is a very important part of the battle against the virus. About half of the genome sequencing in the world is done in Britain. 
Lessons learned are pointed out by the Science Editor of The Times.

During the first wave with the origins of the coronavirus in Wuhan, China, focus shifted to selected countries without much attention to Europe next door to Britain. Much of the mutated virus strains from Europe, from Italy, Spain and other countries cause the epidemic to get out of control. This is being repeated in the second wave.

When the epidemic surged in Kent British health authorites conducted genome sequencing for the virus to find out that there was a variant, a mutation of the virus that was causing a surge. This has helped Britain prepare to tackle the pandemic as it changes with new strains of the virus.

This report in The Guardian says what India urgently needs is for the US to lift export restrictions on supplies for India's vaccine factories, and tools such as genome sequencing to identify and control emerging variants of the coronavirus.

The report also points out that of the 1 billion vaccine jabs about half are in the US and Europe and the low income countries have only a tiny fraction of vaccinations. India which sent 64 million vaccine doses to countries including Brazil and Morocco, Bangladesh, in 3 months prior is reported to have sent only 1.2 million doses this month.

The crisis in India also shows the need says The Guardian for an international approach to the crisis no a country by country approach. It says the Bush plan for Aids and the the 2014 plan for Ebola in West Africa are models of an international approach that is needed now.
