Given new evidence on the B.1.617.2 (Delta) variant, CDC has updated the guidance for fully vaccinated people. CDC recommends universal indoor masking for all teachers, staff, students, and visitors to K-12 schools, regardless of vaccination status. Children should return to full-time in-person learning in the fall with layered prevention strategies in place.
The White House announced that vaccines will be required for international travelers coming into the United States, with an effective date of November 8, 2021.

People Who Are Immunocompromised

People Who Are Immunocompromised

Know how to protect yourself and what to do if you get sick

Updated May 11, 2023

Some people who are immunocompromised (have a weakened immune system) are more likely to get sick with COVID-19 or be sick for a longer period. People can be immunocompromised either due to a medical condition or from receipt of immunosuppressive medications or treatments.

Examples of medical conditions or treatments that may result in moderate to severe immunocompromise include but are not limited to:

  • Active treatment for solid tumor and hematologic malignancies
  • Hematologic malignancies associated with poor responses to COVID-19 vaccines regardless of current treatment status (e.g., chronic lymphocytic leukemia, non-Hodgkin lymphoma, multiple myeloma, acute leukemia)
  • Receipt of solid-organ transplant or an islet transplant and taking immunosuppressive therapy
  • Receipt of chimeric antigen receptor (CAR)-T-cell therapy or hematopoietic stem cell transplant (within 2 years of transplantation or taking immunosuppressive therapy)
  • Moderate or severe primary immunodeficiency (e.g., common variable immunodeficiency disease, severe combined immunodeficiency, DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection (people with HIV and CD4 cell counts less than 200/mm3, history of an AIDS-defining illness without immune reconstitution, or clinical manifestations of symptomatic HIV)
  • Active treatment with high-dose corticosteroids (i.e., 20 or more mg of prednisone or equivalent per day when administered for 2 or more weeks), alkylating agents, antimetabolites, transplant-related immunosuppressive drugs, cancer chemotherapeutic agents classified as severely immunosuppressive, tumor necrosis factor (TNF) blockers, and other biologic agents that are immunosuppressive or immunomodulatory

Talk to your healthcare provider if you have another medical condition or are on medication that may not be reflected above.

If you or someone you live or spend time with is immunocompromised, it is important to have a COVID-19 plan to protect yourself from infection and prepare for what to do if you get sick. Information on this page can help you build a COVID-19 plan for preventing, diagnosing, and treating COVID, so you know what to do and can act quickly if you’re exposed, develop symptoms, or test positive and when COVID-19 levels are increasing in your community.

How to Protect Yourself

Stay up to date on COVID-19 vaccinations

COVID-19 vaccines are effective at protecting people—especially those who are up to date— from getting seriously ill, being hospitalized, and even dying. As with vaccines for other diseases, you are protected best when you stay up to date with your COVID-19 vaccines. The people you live or spend time with can help protect you and themselves by staying up to date on their COVID-19 vaccines too.

Since your immune response to COVID-19 vaccination may not be as strong as in people who are not immunocompromised, you may have different recommendations for COVID-19 vaccines. Learn more about COVID-19 vaccine recommendations for people who are moderately or severely immunocompromised. Talk to your doctor if you have questions about getting a COVID-19 vaccine.

To find COVID-19 vaccine locations near you: Search, text your ZIP code to 438829, or call 1-800-232-0233.

Take extra precautions

Even if you stay up to date on COVID-19 vaccines, taking multiple prevention steps can provide additional layers of protection from COVID-19.

  • Wear a well-fitting, high quality mask or respirator. Properly fitting respirators provide the highest level of protection.
  • Avoid poorly ventilated or crowded indoor settings.
  • When indoors with others, try to improve ventilation as much as possible.
  • Wash your hands often with soap and water or use a hand sanitizer that contains at least 60% alcohol.

What you can do now

  • Know the symptoms of COVID-19.
  • Learn how to check COVID-19 hospital admission levels. Knowing your hospitalization level will help you decide when to add layers of protection, like wearing a mask.
  • Learn about COVID-19 testing, including the pros and cons of different test types, when you should test, and where you can get tested or acquire at-home tests.
  • Know how to reach a healthcare provider right away, including after hours or weekends. Ask them about telehealth appointment options.
  • Have an updated list of all your current medications in case you need to see a different provider.

What to do if you were exposed to COVID-19

  • Determine if you should stay home.
  • Monitor your health for COVID-19 symptoms
  • Get tested at least 5 full days after your exposure to COVID-19, even if you don’t develop symptoms.
  • Wear a high quality mask for 10 full days any time you are around others inside your home or in public. Do not go to places where you are unable to wear a mask.

What to do if you have COVID-19 symptoms

What to do if you have COVID-19

Effective treatments are now widely available and free, and you may be eligible.

  • Contact your healthcare provider, health department, or Community Health Center Externalto learn about treatment options. Don’t delay! Treatment must be started soon after you first develop symptoms to be effective.
  • If you don’t have timely access to a healthcare provider, check if a Test to Treat locationExternal is in your community. You can get tested, receive a prescription from a healthcare provider (either onsite or by telehealth), and have it filled all at one location.
  • Isolate until it’s safe to be around others. CDC recommends that you isolate for at least 10 and up to 20 days. Check with your healthcare provider to learn when you can be around others.
  • Monitor your symptoms. Call your healthcare provider if you develop symptoms that are severe or concerning to you. If you notice emergency warning signs, call 911 or call ahead to your local emergency facility.

Learn How to Get Treatment Quickly

If you have COVID-19, oral antiviral treatments are available for people who are more likely to get very sick. Learn more about COVID-19 treatment.

Don’t delay: Treatment must be started right away to be effective. Talk to your healthcare provider about what treatment options are best for you.

Antiviral treatments

Antiviral treatmentsExternal may help your body fight COVID-19 by stopping the SARS-CoV-2 virus (the virus that causes COVID-19) from multiplying in your body or by lowering the amount of the virus within your body. You can get a prescription from your healthcare provider or a Test to Treat locationExternal. Oral antivirals can be taken at home and must be given within 5 days after the first symptoms of COVID-19 appear.

Convalescent Plasma

Some people with COVID-19 who are immunocompromised or are receiving immunosuppressive treatment may benefit from a treatment called convalescent plasma.  Your healthcare provider can help decide whether this treatment is right for you.

Build Your Personal COVID-19 Plan

Make a COVID-19 plan now so you’re prepared. Consider the ways you will protect yourself and how to be prepared if you get sick with COVID-19. Include how you will adjust your plan if the COVID-19 situation changes in your community.

Your plan should include:

  1. What you’re doing to protect yourself and prepare (in case you get COVID)
  2. What you’ll do if you’re exposed or develop symptoms
  3. What you’ll do if you have COVID-19

Talk with your family, friends, and healthcare provider about your plan

Share your COVID-19 plan with your family, friends, and healthcare providers so they can support your prevention and preparation steps. Consider how others may help you if you get sick and identify the supplies you may need. Be sure to stick to your treatment plans, your routine healthcare appointments, and have all your prescriptions filled. Plan for options for work, childcare, and other responsibilities that may cause stress if you were to become sick.

COVID-19 remains a major health concern and this can be stressful to manage. Understanding what you can do to protect yourself and what to do if you get sick can help minimize that stress. Take as many steps as you can to prevent COVID-19 and get treated quickly if you have COVID-19.
