New JN.1 COVID variant defies immunity, threatens global dominance: Study Warns

NEW DELHI: The JN.1 variant of the SARS-CoV-2 virus not only spreads easily but also seems to resist immunity, according to a study that emphasizes the urgent need for strategies to address its threat to public health.The emergence of JN.1 has sparked global concern due to its distinct genetic features and heightened infectivity. Carrying more than 30 spike protein mutations, including the hallmark Leu455Ser, JN.1 exhibits substantial potential for immune evasion.Researchers from The University of Tokyo, Japan, used genomic surveillance data from across France, the UK, and Spain, uncovering novel findings regarding the virological properties of JN.1.The study, published in The Lancet Infectious Diseases journal, sheds light on the variant’s potential to become the dominant lineage and alerts the global health community.
