Why newest Covid variant ‘JN.1’ is worrying scientists

Scientists are alarmed by a new Covid-19 variant, JN.1, which is believed to be more infectious and capable of evading vaccine immunity. The variant, identified in Luxembourg, has since spread to several countries. It contains a significant number of unique mutations, particularly in the spike protein, that may contribute to increased infectivity and immune evasion. However, initial data suggests that updated vaccines and treatments will still offer protection against JN.1. This variant’s resemblance to earlier variants with distinct spike proteins is also noteworthy.
