When the coronavirus pandemic first struck, opinions of how to combat it typically involved some form of mass “natural immunity” or vaccination. New variants unfortunately seem to have mutations that help it evade both, which is becoming cause for concern:
“An emerging Omicron subvariant has raised concerns about a surge of COVID-19 cases this winter, after it was found to display a worrying proclivity for evading vaccine immunity. BA.2.75.2, as it is called, can largely dodge neutralizing antibodies in the blood and is resistant to several monoclonal antibody treatments, new research from Sweden has discovered.
“While antibody immunity is not completely gone, BA.2.75.2 exhibited far more dramatic resistance than variants we’ve previously studied, largely driven by two mutations in the receptor binding domain of the spike protein,” said corresponding author Ben Murrell in a statement.
