The B.1.640.2 variant was found by scholars at the IHU Mediterranee Infection Institute. According to researchers, it has 46 mutations, which makes it more resistant to immunizations and infectious than Omicron. At least 12 instances of the new type have been discovered near Marseilles, with travel to the African country of cameroon being related. In most regions of the world, however, the Omicron form remains the dominant strain. The threat posed by IHU variants, on the other hand, is fast increasing.
The genomes were retrieved using next-generation sequencing with Oxford Nanopore Technologies on GridION devices, according to a paper published on medRxiv. "The spike protein contains fourteen amino acid changes, including N501Y and E484K, as well as nine deletions. According to the research report, "this genotype pattern led to the creation of a new Pangolin lineage dubbed B.1.640.2, which is a phylogenetic sister group to the existing B.1.640 lineage renamed B.1.640.1."
