President Trump Urges COVID 19 Survivors To Donate Plasma

Convalescent plasma has been used for more than a century to treat people stricken with infectious diseases. People who have already recovered from the virus build up antibodies in their blood plasma that can be beneficial to people who still have the illness. The Trump administration identified plasma as a potential therapy early in the pandemic, and the FDA selected Mayo Clinic to make it available on a compassionate-use basis across the country, called an “expanded access program,” that was closely coordinated with the agency.
