Please note that for this treatment to be impactful, it must be given within 10 days of developing COVID-19 symptoms.

Information & eligibility 

What is monoclonal antibody treatment for COVID-19?

Antibodies are naturally made in our bodies to fight infection. When our immune system meets a new foreign substance in the body, it makes new antibodies that attack the foreign substance. The next time that substance shows up, our immune system can produce the same antibodies to help the body fight it off before it can make a person sick. These types of naturally occurring antibodies provide active immunity. Monoclonal antibodies are laboratory-made proteins designed to mimic the body’s ability to fight off viruses and pathogens. 

Monoclonal antibody treatment for COVID-19 has received emergency use authorization by the Food and Drug Administration (FDA) as an investigational medicine used for the treatment of COVID-19 patients at high-risk of developing severe illness.
