What is this? Convalescent plasma and hyperimmune immunoglobulin have been suggested as possible treatments for COVID-19.

In this Cochrane Rapid Review, the authors searched for studies that had evaluated convalescent plasma or hyperimmune immunoglobulin for people with COVID‐19, irrespective of disease severity, age, gender or ethnicity. They did not restrict their searches by type or language of publication and searched for articles published between 1 January 2019 and 23 April 2020. They included 7 case‐series and one prospectively planned, single‐arm intervention study (total: 32 participants), and rated these as very low‐certainty evidence, with all studies being at high risk of bias. The authors also identified a further 48 ongoing studies evaluating convalescent plasma (47 studies) or hyperimmune immunoglobulin (1), of which 22 are randomized trials.

What was found: At the time of this review, the available research showed that the benefits and harms of convalescent plasma or hyperimmune immunoglobulin are uncertain. The review will be updated as a living systematic review and these updates are expected to show different results to the current results.
