Scientists have warned that the Omicron subvariants driving COVID cases among Americans appear to elude the immune system as well as medical treatments for the virus.

In a new study published in the scientific journal Cell, researchers from Columbia University and the University of Michigan warned that the Omicron subvariants BQ.1, BQ.1.1, XBB and XBB.1 were “the most resistant [COVID] variants to date.”
