How do Monoclonal Antibodies Work?

When our bodies' are infected with viruses, we naturally produce antibodies, which are like soldiers, to fight the infection. However, without a vaccine or treatment, the process of building antibodies takes time. The monoclonal injection contains lab-made antibodies that will mimic your immune system's function and help you recover faster. 

Monoclonal antibodies like the ones used in the Regeneron COVID-19 treatment, have been studied by the FDA to treat conditions like cancers and autoimmune diseases.
