Antibodies in convalescent plasma may inhibit viremia, making it an efficient treatment. However, this treatment has shown to be less effective in the late stages of the disease and may be difficult to obtain because large amounts of plasma are required and transfusions are typically done in a hospital setting. Though there is not strong evidence that this treatment causes severe adverse events, the patient may experience mild fever, allergic reactions, bronchospasms, transfusion-related acute lung injury, and circulatory overload in patients with cardiorespiratory disorders.
