When fighting illness, the body produces antibodies-proteins that counteract a pathogen. Antibodies remain in plasma for weeks or months after recovery. The antibodies in patients who have recovered from COVID-19 attack the virus and can potentially be useful as a treatment for the virus.
The American Red Cross is accepting plasma donations from individuals who have recovered from COVID-19. For more information or to determine your eligibility call 800-733-2767 or visit the Plasma Donations from Recovered COVID-19 Patients page.
