A big step forward in COVID-19 treatment and a breakthrough for a Florida-based nonprofit blood center serving the southeast. OneBlood just became the first blood center to get full FDA approval to give high-titer COVID-19 convalescent plasma from people who recovered from COVID-19 to those with COVID who are also immunocompromised. “This license is something new and very important, especially for the ten million people in the United States who are immunosuppressed and can benefit from this,” said Dr. Rita Reik, Chief Medical Officer of OneBlood.
