Mobile Treatment Clinics Discontinued

The mobile mAb buses that were deployed across the state through the Colorado Department of Public Health and Environment have been discontinued due to Omicron and the shortage of sotrovimab (the treatment used). 

Contact your health care provider to see what options may be available to you.

About the Treatment

Antibodies are proteins that exist in our immune system. They recognize and defend against harmful viruses and bacteria.

Monoclonal antibodies are made in a laboratory and designed to target a specific bacteria or virus, like SARS-CoV-2, which is the virus that causes COVID-19. Monoclonal antibodies are given to patients through a series of injections (shots). They must be given before someone is hospitalized with COVID-19.

Find Out if You Qualify

You might be eligible for treatment if you have:

  • Tested positive for COVID-19, your symptoms started within the last 10 days,
  • you aren’t hospitalized or on oxygen due to COVID-19,
  • and you are at risk of getting very sick without treatment.

People as young as 12 years old can get monoclonal antibody treatment. 

People at risk of getting very sick include:

People who are 65 years or older.

Older individuals are at an increased risk to get more severely ill or hospitalized due to COVID-19. 

These treatments can reduce your risk if you have been exposed to the virus.

People who are obese or overweight.

This includes adults with a BMI of 25 or more.

It also includes children age 12 to 17 who have a BMI in the 85th percentile or higher for their age and gender.

People with certain underlying conditions.

This includes pregnancy. See a full list from the CDC by clicking here.


Monoclonal antibody therapy is not a substitute for a COVID-19 vaccine

Getting vaccinated is the best way to keep from getting sick with COVID-19.

How do I find out if I’m eligible?

You may be eligible if you have tested positive for COVID-19, have mild to moderate symptoms, and are at high risk of developing severe illness; or if you are not fully vaccinated (or may not respond to the vaccine), have been exposed to COVID-19, and are at risk of developing severe illness. Monoclonal antibody therapy is not for use in patients who are hospitalized, on oxygen for COVID-19 treatment, or require an increase in baseline oxygen flow rate due to COVID-19.

What is the cost?

Monoclonal antibody therapy is free. It is paid for through Medicaid, Medicare, and many health insurance plans. Some providers may charge an administration fee.

Are there any side effects?

Most people tolerate monoclonal antibody infusions very well. Some people may experience infusion-related side effects, such as nausea and dizziness, that are short-lived and go away on their own. As with any medication, there is the potential for mild or more severe allergic reactions, which are uncommon.
