Rise of ‘Alarming’ Subvariants of COVID ‘Worrisome’ for Winter

Medscape (Dec. 16, 2022) – It’s a story perhaps more appropriate for Halloween than for the festive holiday season, given its scary implications. Four Omicron subvariants of the virus that causes COVID-19 will be the most common strains going from person to person this winter, new research predicts.

Not too dire so far, until you consider what else the researchers found.

The BQ.1, BQ1.1, XBB, and XBB.1 subvariants are the most resistant to neutralizing antibodies, researcher Qian Wang, PhD, and colleagues report. This means you have no or “markedly reduced” protection against infection from these four strains, even if you’ve already had COVID-19 or are vaccinated and boosted multiple times, including with a bivalent vaccine.
