ROCKFORD — The Rock River Valley Blood Center is collecting plasma from recovered COVID-19 patients, joining other blood centers nationwide in an effort to help care for individuals affected by the virus.

Convalescent plasma is collected from recovered patients and administered to people currently diagnosed with COVID-19. Donors must have proof of a positive nasal swab test for COVID-19 and be 28 days out from their last symptoms. They also must meet the requirements to donate blood.

While there is no proven treatment for COVID-19, it is possible that convalescent plasma collected from recovered COVID-19 patients contains antibodies to SARS-CoV-2 (the virus that causes COVID-19) and might provide passive immunity for some COVID-19 patients.
