What is monoclonal antibody treatment?

When you get infected with a virus, such as severe acute respiratory syndrome coronavirus 2 (SARS­CoV-2), the virus that causes COVID-19, your immune system creates antibodies to fight it off. It takes time for your body to make these antibodies, which allows the infection to get worse and make you sicker. Monoclonal antibodies are laboratory-made proteins that mimic the immune system's ability to fight off harmful antigens such as viruses. 

The St. Charles Pulmonary Clinic uses REGEN-COV as its chosen brand of monoclonal antibody treatment. REGEN-COV contains two monoclonal antibodies that neutralize SARS-CoV-2 to help patients fight and recover from COVID-19. Being treated with REGEN-COV antibodies as soon as you are diagnosed with COVID-19 may limit the amount of virus that develops in your body, which may help you recover from the infection.
