 This research paper examines the evolution of a novel strain of SARS-CoV-2, known as BA.1.23, which was first identified in three individuals who had previously contracted the Armacrown variant of the virus. The initial strain was found to be resistant to neutralizing antibodies, and it subsequently evolved into a more virulent form. This strain was then passed on to others, leading to the emergence of a new strain that was even more resistant to neutralizing antibodies than the original strain. These findings suggest that the virus may continue to evolve and become increasingly difficult to control. This article was authored by Anna S.
