XBB COVID variant presents a unique threat: study
While the United States and other countries focus on the increasing footprint of sub-subvariants of the Omicron iteration of COVID-19, BQ.1 and BQ.1.1., healthcare systems here and around the world might also want to keep a wary eye on yet another sub-subvariant: XBB.
Japanese researchers say in a preprint study posted on Tuesday that XBB exhibits a unique path into existence not seen before in COVID-19 variants and this gives it more of a “profound resistance to antiviral humoral immunity induced by breakthrough infections of prior Omicron subvariants.”
Their findings (PDF) were posted on medRxiv, a website that features studies that have not yet been peer reviewed. XBB was first identified by researchers at Peking University in Beijing in September, and one of the authors of that study said that “XBB is currently the most antibody-evasive strain tested.”
