How can convalescent plasma be used to treat COVID-19?
The blood from people who recover from COVID-19 contains substances called antibodies, which are capable of fighting the virus that causes the illness. For some other diseases caused by respiratory viruses, giving people the liquid portion of blood that contains these antibodies, called plasma, obtained from those who have recovered from the virus, may lead to more rapid improvement of the disease. Patients with COVID-19 may improve faster if they receive plasma from those who have recovered from COVID-19, because it may have the ability to fight the virus that causes COVID-19.
Can you donate convalescent plasma after getting the COVID-19 vaccine?
At this time individuals who have received a COVID-19 vaccine are not able to donate convalescent plasma with the Red Cross. (source – Red Cross) However, other plasma donation providers may allow convalescent plasma donation after vaccination if donors meet Food and Drug Administration (FDA) eligibility criteria. (source – FDA) To learn more about convalescent plasma donation requirements visit the FDA (source – FDA) or talk to your local plasma donation provider. (last updated 4/6/2021)
How long does it take to get better from COVID-19?
Those with a mild case of COVID-19 usually recover in one to two weeks. For severe cases, recovery can take six weeks or more, and for some, there may be lasting symptoms with or without damage to the heart, kidneys, lungs and brain.
How long does it take to develop COVID-19 antibodies?
After infection with the COVID-19 virus, it can take two to three weeks to develop enough antibodies to be detected in an antibody test, so it's important that you're not tested too soon. Antibodies may be detected in your blood for several weeks after you recover from COVID-19.
Is it recommended to take antibody tests after receiving the COVID-19 vaccine?
FDA reminds the public and health care providers that results from currently authorized SARS-CoV-2 antibody tests should not be used to evaluate a person’s level of immunity from COVID-19 at any time, and especially after the person received a COVID-19 vaccination.
Do vaccinated people who got COVID-19 have more COVID-19 antibodies?
Lab research suggests that people with hybrid immunity make higher levels of virus-fighting antibodies than people who've been either vaccinated or infected. Their antibodies are also more potent than those in people who've only gotten their initial COVID-19 vaccines.
Can I stay at home to recover if I have only mild symptoms of COVID-19?
Most people with COVID-19 have mild illness and can recover at home without medical care. Do not leave your home, except to get medical care. Do not visit public areas.
Can COVID-19 symptoms get worse as it goes along?
COVID-19 can cause symptoms that are mild at first, but then become more intense over five to seven days, with worsening cough and shortness of breath.
How long do lingering symptoms last after COVID-19?
Symptoms. People with post-COVID conditions (or long COVID) may experience many symptoms. People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.
Do people produce COVID-19 antibodies after infection?
Most people who've recovered from COVID-19 do make antibodies against the virus.
When should you take a COVID-19 test after exposure?
YES: Get tested at least 5 days after exposure. Follow quarantine guidance while waiting to test.
Can you get COVID-19 if you already had it and have antibodies?
It is important to remember that some people with antibodies to SARS-CoV-2 may become infected after vaccination (vaccine breakthrough infection) or after recovering from a past infection (reinfected).
Recommendations
- The COVID-19 Treatment Guidelines Panel (the Panel) recommends against the use of CCP that was collected prior to the emergence of the Omicron (B.1.1.529) variant for the treatment of COVID-19 (AIII).
- The Panel recommends against the use of CCP for the treatment of COVID-19 in hospitalized, immunocompetent patients (AI).
- The COVID-19 Treatment Guidelines Panel (the Panel) recommends against the use of CCP that was collected prior to the emergence of the Omicron (B.1.1.529) variant for the treatment of COVID-19 (AIII).
- The Panel recommends against the use of CCP for the treatment of COVID-19 in hospitalized, immunocompetent patients (AI).
- There is insufficient evidence for the Panel to recommend either for or against the use of high-titer CCP that was collected after the emergence of Omicron for the treatment of immunocompromised pa...
Rationale
- Regarding the Use of COVID-19 Convalescent Plasma Collected Prior to the Emergence of the O…
The Omicron variant is the dominant SARS-CoV-2 variant currently circulating in the United States. Although in vitro data suggest that the CCP collected from vaccinated and unvaccinated individuals who have recovered from Omicron infection exhibits neutralizing activity against the … - For Hospitalized, Immunocompetent Patients
Under the revised EUA, the use of CCP is no longer authorized for hospitalized patients who do not have immunosuppressive disease or who are not receiving immunosuppressive treatments. Clinical data on the use of CCP for the treatment of COVID-19 in hospitalized, immunocompeten…
Considerations in Pregnancy
- The safety and efficacy of using CCP during pregnancy have not been evaluated in clinical trials, and published data on its use in pregnant individuals with COVID-19 are limited to case reports.51 Pathogen-specific immunoglobulins (Ig) are used clinically during pregnancy to prevent infection from varicella zoster virus and rabies virus and have been used in clinical trials of congenital cyt…
Considerations in Children
- The safety and efficacy of CCP have not been systematically evaluated in pediatric patients. Published literature on its use in children is limited to case reports and case series. A few clinical trials that are evaluating the use of CCP in children are ongoing. The use of CCP may be considered on a case-by-case basis for hospitalized children who are immunocompromised an…
Adverse Effects
- The available data suggest that serious adverse reactions following the administration of CCP are infrequent and consistent with the risks associated with plasma infusions for other indications. These risks include transfusion-transmitted infections (e.g., HIV, hepatitis B, hepatitis C), allergic reactions, anaphylactic reactions, febrile nonhemolytic reactions, transfusion-related acute lung …
Clinical Trials
- Several randomized clinical trials that are evaluating the use of CCP for the treatment of COVID-19 are underway. Please see ClinicalTrials.govfor the latest information.
