The purpose of this study is to evaluate the safety of administration of plasma containing antibodies to the SARS-CoV-2 virus (i.e., convalescent plasma) and if it is able to prevent disease or lessen the severity of disease in individuals who are at high risk of developing COVID-19 due to a recent exposure. This study will also measure the level of anti-SARS-CoV-2 antibodies in patient's blood after the administration of the convalescent plasma.


People who become infected with a virus such as SARS-CoV-2 usually develop an immune response and produce antibodies against the virus. Antibodies are natural proteins made by the body's immune system that attack viruses and other germs. These antibodies are found in plasma, which is the yellow, clear part of the blood. There have been other studies using plasma to treat other types of viruses that showed some positive results. Human plasma containing antibodies to the SARS-CoV-2 virus is an option for prevention and treatment of COVID-19. This type of treatment, known as passive antibody therapy, could be rapidly available when there are sufficient numbers of people who have recovered from infection and can donate antibody-containing plasma. In contrast to vaccination strategies, which begin to provide protection weeks after administration, antibody-containing plasma would provide its protective benefits immediately. Additionally, passive antibody therapy may be the only way to provide immunity for some immunocompromised patients who do not respond to vaccines.

This research will evaluate the safety of administration of plasma containing antibodies to the SARS-CoV-2 virus (i.e., convalescent plasma). The research will also measure the level of anti-SARS-CoV-2 antibodies in patient's blood after the administration of the convalescent plasma.

Inclusion Criteria

Is your age between 1 yrs and 18 yrs?
Gender: Male or Female
Do you have Corona Virus Infection?
Do you have any of these conditions: Coronavirus or Coronavirus Infection or Corona Virus Infection?
Between 1 month and 18 years of age at the time of consent
Determined to be at high-risk for severe SARS-CoV-2 disease based on the American Academy of Pediatrics definition of immunocompromised children and reported high-risk Pediatric subpopulations. These include the following groups: Immunocompromised, Hemodynamically significant cardiac disease {e.g. congenital heart disease}, Lung disease with chronic respiratory failure, Infant, i.e. child 1 year old
Confirmed SARS-CoV-2 infection OR high-risk exposure as defined
Confirmed infection: Child who tested positive for COVID-19 and is no more than 96 hours after onset of symptoms (and within 120 hours at the time of receipt of plasma)
High-risk exposure: Susceptible child who was not previously infected or otherwise immune to SARS-CoV-2 and exposed within 96 hours prior to enrollment (and within 120 hours at the time of receipt of plasma). Both criteria below should be met: A household member or daycare center (same room) exposure to a person with [confirmed SARS-CoV-2 OR with clinically compatible disease in regions with widespread ongoing transmission] and a negative for SARS-CoV-2 (nasopharyngeal swab)
Subject is judged by the investigator to have the initiative and means to be compliant with the protocol
Subjects or their legal representatives must have the ability to read, understand, and provide written informed consent for the initiation of any study related procedures

Exclusion Criteria

History of severe reactions (e.g. anaphylaxis) to transfusion of blood products. Subjects with minor reactions such as fever, itching, chills, etc. that resolve spontaneously or respond to pre-medications, and that do not represent more significant allergic reactions will not be excluded
Inability to complete therapy with the study product within the stipulated time frame outlined above
Female subjects in child-bearing age with a positive pregnancy test, breastfeeding, or planning to become pregnant/breastfeed during the study period
Subject / caregiver deemed by the study team to be non-compliant with the study protocol
Clear my responses
