    1. Larger, blinded, randomized control trials are still ongoing to confirm the efficacy of CP treatment, the RECOVERY trial in Oxford is one such Phase 3 trial of CP (NCT04381936).

      The RECOVERY trial in Oxford, with 5795 patients who were randomly allocated to receive convalescent plasma treatment and 5763 who received usual care alone, found that there was no statistically significant difference for 28-day mortality (24% for both groups, p-0.93) or the proportion of patients discharged from hospital within 28 days (66% CP vs 67% control, p=0.50) for the two groups. Additonally for patients without mechanical ventilation, there was no stastically significant difference in the intubation rate (28% CP vs 29% control, p=0.79).

      The trial showed convalescent plasma therapy had no benefit to patients with COVID-19. As a result the UK's health service has stopped collecting convalescent plasma from patients who had recovered from COVID-19.
