Tiffany Pinckney remembers the fear she felt when the coronavirus she suffered from made it very difficult to breathe. So, when she recovered, the New York City woman became one of the country’s first survivors to donate her blood. That blood may now help other seriously ill patients. Pinckney told the Associated Press it was overwhelming to know that in my blood, there may be answers. Doctors around the world are reusing a treatment for infections that is about 100 years old, giving blood plasma from recovered patients to sick ones. Plasma is the yellowish liquid part of blood. The blood from former patients is filled with immune molecules that can help survivors defeat COVID 19, the disease caused by the coronavirus. Such donations have already been made by recovered patients in Houston and New York. Now, hospitals and blood centers in other areas are preparing for possibly hundreds of survivors to donate. Doctors do not know if the treatments will be successful.
