Regeneron Pharmaceuticals’ monoclonal antibody treatment for COVID-19 has “diminished potency” when used against the omicron variant, while AstraZeneca plc’s antibody product “retained neutralizing activity” against the new variant. The antibody treatments remain the standard of care for unvaccinated COVID-19 patients with severe disease. Regeneron emphasized that its treatment is effective against the delta variant. However, omicron has become the dominant variant in recent days: the Associated Press reported 73% of new infections last week were omicron.
