Convalescent plasma has been used as a treatment for many infections, including coronaviruses such as SARS, and yielded positive results in healing patients. This method is being applied for COVID-19, but scientists are still unsure how effective it is for this virus.
What scientists know is that convalescent plasma is not harmful, so it has been approved as one of the methods for treating COVID-19 patients. It works by removing blood plasma containing antibodies from recovered COVID-19 cases and giving it to COVID-19 patients.
