My husband gave blood today. They only test the unvaxxed for antibodies & if they have them, they use their blood as treatment for those at risk of adverse outcomes. Why can’t they use blood of vaxxed who also had Covid? Real question for MDs. What’s wrong with vaxxed blood?

We continue to evaluate the feasibility & timeline to implement the necessary changes, alongside evolving hospital needs. We're committed to building a readily available supply of convalescent plasma to ensure patients with COVID-19 have all treatment options available. (3/3)

While updated FDA guidance allows donations from those who received a COVID-19 vaccine to be processed into convalescent plasma, it would require complex Red Cross system updates & delay our ability to meet immediate needs of immunocompromised patients with the virus. (2/3)
