             Cardiovascular disease; Sickle cell disease; Pulmonary disease; Neurologic disease;
             Immunosuppressed ; Baseline medical complexity (gastrostomy- or
             jejunostomy-dependence, parenteral nutrition dependence, tracheostomy-dependence,
             Baseline oxygen requirement, use of Continuous positive airway pressure [CPAP]/
             Bilevel positive airway pressure [BiPAP]/ventilator support).

        Exclusion Criteria

          -  Participant is pregnant or breastfeeding.

          -  Participant is currently hospitalized, or judged by the investigator as likely to
             require hospitalization in the next 24 hours, due to severe or critical COVID-19.

          -  Multisystem inflammatory syndrome in children (MIS-C).

          -  Prior, current, or planned future use of any of the following treatments during the
             study period: COVID-19 convalescent plasma, Monoclonal antibodies (mAbs) against
             Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) (for example [e.g.],
             casirivimab/imdevimab), intravenous immunoglobulin (IVIG) for any indication, or
             dexamethasone specifically for treatment of COVID-19.

          -  Current use of COVID-19 treatment (authorized, approved, or investigational).

          -  The following exclusions related to use of an authorized or approved vaccine for
             SARS-CoV-2 are applicable:

               1. Receipt of any authorized or approved vaccine for SARS-CoV-2 within 48 hours
                  prior to dosing.

               2. Planned use of any authorized or approved vaccine for SARS-CoV-2 within 90 days
                  of study drug administration per current Centers for Disease Control and
                  Prevention (CDC) recommendations.

          -  Receipt of any non-SARS-CoV-2 vaccines within 14 days (for non-live vaccines) or 28
             days (for live vaccine) of screening.

          -  Currently enrolled in another clinical study.

          -  Infants <24 weeks of age: maternal receipt of IVIG, SARS-CoV-2-directed convalescent
             plasma or SARS-CoV-2-directed mAb(s) within 3 months prior to birth or within 5
             half-lives of the investigational product (whichever is longer).
