Monoclonal Antibodies Treatment

What are Monoclonal Antibodies? 

Your body naturally makes antibodies to fight infection. However, your body may not have antibodies designed to recognize a novel (or new) virus like SARS-CoV-2, the virus that causes COVID-19. Monoclonal antibodies, or mAbs, are made in a laboratory to fight a particular infection (in this case, SARS-CoV-2) and are given to you directly in an infusion. So the mAb treatment may help if you are at high risk for serious symptoms or a hospital stay.

A mAb treatment for COVID-19 is different from a COVID-19 vaccine. The vaccine triggers your body’s natural immune response, but this can take weeks to develop enough antibodies against a virus. So if you have the virus, the mAb treatment gives your body the antibodies it needs to protect itself. The mAb treatment does not replace the need for the immunity from the vaccine but it can help you if you are at risk for developing serious COVID-19.

What Can I Expect From Treatment? 

The mAb treatment is usually offered at an infusion center because the treatment is given through an intravenous (IV) infusion or shots. Depending on the mAb treatment you receive, the whole process takes about 2 to 3 hours. First, the medical staff conduct a screening; then they start an IV, which delivers the mAbs to your body in just over an hour.

 It takes less time if the mAb treatment is offered to you as a series of shots. Afterward, the medical team will have you stay at the infusion center for another hour to be sure you do not have an allergic reaction or any other side effects. These reactions are rare, but the medical team must observe you for this hour and can respond quickly if you have a reaction. You will be released to go home after the medical team has monitored you following your infusion.

Even if you start feeling better, it is important to know that you could still spread the virus for a while. So, you will need to isolate yourself (be alone) until all of these things happen:

At least 10 days have passed since your first symptoms of COVID-19
You have not had a fever in at least 24 hours, without taking any medicine that reduces fever
Your other symptoms of COVID-19 are improving

Can Monoclonal Antibody Treatment Make Me Sick? 

Antibody treatments do not contain any live SARS-CoV-2, so there is no risk you will get COVID-19 from mAb treatment. However, the antibody treatment may have side effects:

Allergic reactions can happen during and after an antibody infusion. Tell your healthcare professional right away if you get any of the following signs and symptoms of an allergic reaction: fever, chills, nausea, headache, shortness of breath, low or high blood pressure, rapid or slow heart rate, chest discomfort or pain, weakness, confusion, feeling tired, wheezing, swelling of your lips, face, or throat, rash including hives, itching, muscle aches, feeling faint, dizziness, and sweating.

An infusion of any medicine may cause brief pain, bleeding, bruising of the skin, soreness, swelling, and possible infection at the infusion site.


These are not all the possible side effects of antibody treatment. Serious and unexpected side effects may happen. Some possible risks from antibody treatment are:

It may interfere with your body’s ability to fight off a future infection of SARS-CoV-2.
It may reduce your body’s immune response to a vaccine for SARS-CoV-2.


The mAb treatments for COVID-19, like other treatments authorized for emergency use by the U.S. Food and Drug Administration, are still being studied. So it is possible that we do not know all the risks yet. As researchers continue to study the virus and how mAb treatment affects it, we will learn more about these possible risks. If you have any questions, please talk with your healthcare professional.
