Treatment for COVID-19


Have you had a positive test for COVID-19? Do you have symptoms? Has it been less than 7 days since your symptoms started?

You might meet the criteria for monoclonal antibody treatment. While the treatment helps reduce serious outcomes caused by COVID-19, it is NOT a substitute for full vaccination.

To qualify, you must:

  • Have a positive COVID-19 test, AND;
  • Have symptoms that began within the last 7 days, AND;
  • Be unvaccinated or partially vaccinated, AND;
  • Have no prior history of COVID-19 infection, AND;
  • Be older than 40 years of age, OR;

  • Be unvaccinated or partially vaccinated, AND;
  • Have no prior history of COVID-19 infection, AND;
  • Be 18-40 years old, AND;
  • Have a serious health condition which may include diabetes, smoking, obesity, heart disease, kidney disease, lung disease, or cancer, OR;

  • Be 18 years or older (regardless of whether you are vaccinated or previously infected with COVID-19), AND;
  • Be immunocompromised due to a medical condition or treatment.


All people must be able to receive treatment within 7 days of symptom onset to be eligible.


Find Out If You Qualify

If you have tested positive for COVID-19, your symptoms began less than 7 days ago, and you meet the above criteria, please call Health Links - Info SantÚ at 204-788-8200 or 1-888-315-9257 to find out if you qualify to receive monoclonal antibodies. If you are eligible, you will be referred for treatment.

If you have a health condition, you can also discuss with your health care provider whether monoclonal antibody treatment is right for you.


A new monoclonal antibody treatment for COVID-19 has recently received interim approval by Health Canada for early treatment of mild to moderate COVID-19 illness in people at risk of becoming severely ill. Health Canada has authorized the use of this drug based on limited clinical testing in humans, and reviews of safety, efficacy, and quality. Antibodies are used by your immune system to fight off foreign objects. This treatment may be offered to unvaccinated people who are at risk of severe disease due to their age and/or medical condition, as well as people with weakened immune systems who may not respond to vaccination. It is the first treatment to be offered to outpatients in Manitoba and is administered by intravenous infusion, or through the vein, within 7 days of symptom onset. This treatment may help reduce the risk of hospitalization from COVID-19.


COVID-19 illnesses have ranged from very mild to severe, including illness resulting in death. People of all ages with severe chronic medical conditions like heart disease, lung disease, diabetes, and other conditions including obesity, seem to be at higher risk of being hospitalized for COVID-19. Older age, with or without other conditions, also places people at higher risk of being hospitalized for COVID-19. If you have not been vaccinated, or are at high risk of severe disease, you should get tested early if you develop symptoms of COVID-19, and check to see if you are eligible for treatment.


This treatment uses laboratory-made proteins, or antibodies, to give people with no prior antibodies to COVID-19 an initial immune response that may prevent serious illness. Antibodies are used by your immune system to fight off foreign substances. Monoclonal antibodies give your body temporary antibodies faster than your body can make them. The treatment may also help protect against severe COVID-19 illness in people with weakened immune systems who may not generate a strong response to the COVID-19 vaccines. This treatment is only effective in the very early phase of COVID-19 infection.

Monoclonal antibody treatment can only be given to you once. It is delivered intravenously, or using a needle into your vein. The antibodies attach to the spike protein of the coronavirus, and keeps the virus from entering and infecting healthy cells within your body to prevent COVID-19 symptoms from getting worse.


Contracting and being treated for COVID-19 does not offer the same protection to vaccination and it is possible to become sick again with COVID-19. The best way to prevent COVID-19 is to be fully vaccinated. You must wait to be vaccinated for 90 days after treatment because the antibodies in the treatment may also prevent your immune system from responding to the vaccine. Find a vaccination clinic near you.


There are currently two types of treatments available:

If you have been referred to a clinic for monoclonal antibody treatment and have not received an appointment within 24 hours, please call Health Links - Info SantÚ at 204-788-8200 or 1-888-315-9257


Health care providers can refer eligible inpatients (non-COVID-19 related admission) and outpatients. For more information, visit https://sharedhealthmb.ca/covid19/mab/


Manitoba's COVID-19 treatment approach is based on current and developing medical evidence. As the situation evolves, treatment options will be continually reviewed. This website will be updated regularly to reflect current information on updated eligibility and access.


If you meet all eligibility criteria and your self-administered rapid antigen test shows a positive result, you may be referred for treatment. Contact your health-care provider or Health Links-Info SantÚ to confirm your eligibility and the location where you may be able to receive treatment.  A health care provider will repeat a rapid antigen test to confirm the self-administered test result if a PCR test result isn’t available at the time of your assessment.
