Some researchers and doctors have started using plasma from people recovering from COVID-19 to treat others who have developed the disease

In the search for an effective treatment for COVID-19, an old method of fighting infectious diseases has recently resurfaced: transfusions with convalescent plasma. Plasma is a component of blood.

This method has a simple premise. The blood of people who have recovered from an infection contains antibodies. Antibodies are molecules that have learned to recognize and fight the pathogens, such as viruses, that have caused disease.

Doctors can separate plasma, one of the blood components that contain such antibodies, and administer it to people whose bodies are currently fighting an infectious disease. This can help their immune systems reject the pathogen more efficiently.

Recently, researchers and healthcare professionals have been looking into the possibility of using this method to treat people with COVID-19, the respiratory disease caused by the SARS-CoV-2 virus.

“This [therapy] will provide something that is immediately available. I think what you [will] see in the United States [will be its] continuous use. I hope that there will be better options down the line. For example, [I and my colleagues] are trying to make antibodies from convalescent plasma that may become available in a few months. There is also a hope for monoclonal antibodies in the future and various antivirals.”
