This a phase II, proof-of-concept study. In the present study, we investigate if the
administration of blood-plasma from patients recovered from COVID-19, could be effective to
treat patients who are severely ill because of a COVID-19 infection. The general idea behind
the transfusion, is that plasma of recovered patients contains antibodies that could
eliminate the novel coronavirus causing COVID-19, and lead to a less severe course of the
disease, or a faster healing. Simply put, in this study we would like to investigate whether
'borrowed immunity' from a person who has cured from this disease, could be applied to cure
other patients more rapidly.
