A potential treatment for Covid using blood plasma does not reduce deaths among hospital patients, trials show.
The results are a blow to researchers and the NHS, which led the drive to collect plasma donations.
This arm of the Recovery trial, which is investigating a number of promising Covid treatments, has now been closed.
The Oxford researchers involved say they are “incredibly grateful” for the contribution of patients across the country.
Donations of plasma were temporarily suspended, according to NHS Blood and Transplant.**
There had been huge international interest in the role of convalescent plasma as a possible treatment for hospital patients with Covid-19.
