Summary

This study collects blood plasma from people who have recovered from COVID-19 to learn more about the antibodies it contains. Researchers will give this plasma to people currently sick with COVID-19 and track how their health changes. The goal is to understand which antibody profiles lead to better outcomes, not to provide a proven treatment. About 95 adults who have recovered from or are currently infected with COVID-19 will take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

For COVID-19 convalescent individuals: * Age: ≥ 18 years * Evidence of COVID-19 documented by a laboratory test either by: a diagnostic test (e.g., a NP swab) at the time of illness OR a positive serological test for SARS-CoV-2 antibodies after recovery, if prior diagnostic testing was not performed at the time COVID-19 was suspected. Note: If volunteers can't provide evidence of COVID-19, but are otherwise eligible, then we will test them for SARS-CoV-2 antibodies to confirm eligibility. * Be willing to complete a pre-screening questionnaire * Be willing to donate blood samples * Permit medical record review * For prospective CCP donors only: weigh more than 110 pounds and be in general good health For (COVID-19 convalescent plasma (CCP) recipients: * Be enrolled in a clinical trial involving the infusion of CCP for the treatment of COVID-19. * Be willing to provide blood samples * Permit medical record review
