What is Monoclonal Antibody Therapy (mAb)?

Your body naturally makes antibodies to fight infection. However, your body may not have antibodies designed to recognize a new virus like SARS-CoV-2, the virus that causes COVID-19.

Monoclonal antibodies, or mAbs, are lab-produced molecules that help your body fight off illness. Monoclonal antibodies can restore, boost or imitate your immune system’s response to the virus by replacing your natural antibodies. This treatment is administered by infusion. (source)
