In the midst of the COVID-19 pandemic, does convalescent plasma from recovered patients offer fresh hope for those who are critically ill?
Is Convalescent Plasma an Answer?
Convalescent plasma is collected from those who have recovered from an illness (in this case COVID-19) and transfused to those currently ill. Passive antibody therapy is an old idea, but how much will it help in the current pandemic? Much current research seeks to answer that question.
My guests, Drs Pampee Young and Ralph Vassallo, are the medical leaders of the two largest blood collectors in the United States, the American Red Cross and Vitalant, respectively. They recorded separate interviews with me on April 30, 2020, to discuss what their organizations are doing to make COVID-19 convalescent plasma available for research use. We will also discuss the current pathways US hospitals must follow to transfuse this product.
PLEASE NOTE:
Things are moving quickly! One day after I recorded these interviews, the FDA updated their donor criteria. Please stick around until the end of the episode for an update.

Thank you very much. It was very interesting and eyes opening. Greetings from Israeli blood devices.
Thank you.
Great podcast. Very informative.
Still many questions left to be answered,such as what is the best therapeutic titer.
Couldn’t agree more, Maria, but that’s kind of the point for me: Blood centers are collecting and offering the product so it can be studied.
Silly Joe, you’re no dummy. 😉
Very informative. I do believe we need follow up studies on patients who have been transfused Ruth CCP and at what level of severity of the disease they were when they recurved the CCP
I believe you are correct, Laura! In my opinion, we’ve got to have more patients in randomized studies to really know how effective CCP is and in which populations. However, if the upcoming things people are working on, like vaccines and monoclonal immunotherapies, happen soon, we may never get those high-quality studies.
