convalescent serum

Among the most favoured possible treatments for COVID-19 is convalescent serum.  This is serum taken from the blood of patients who have recovered from the coronavirus. It is rich in antibodies, and can be administered as a prophylactic to people who do not have the disease, or as a treatment to people who do have it in order to boost their immune systems.  A few small trials have produced positive results.  The preparation of the serum for safe use is standard and minimal.
