Q: Are individuals who received a COVID-19 vaccine eligible to give COVID-19 convalescent plasma?

A: The FDA allows people who have received a COVID-19 vaccine to donate dedicated COVID-19 convalescent plasma within six months of their infection of the virus, based on data that antibodies from natural infection can decline after six months however, the Red Cross has discontinued our convalescent plasma collection program.

Throughout the pandemic, the Red Cross has adapted its collection of lifesaving products to meet the needs of all patients including COVID-19 patients. Due to the decline in hospital demand and because the Red Cross and our industry partners have been able to build a sufficient supply of convalescent plasma to meet the foreseeable needs of COVID-19 patients the Red Cross stopped collecting convalescent plasma completely on June 14.

The Red Cross is grateful to the tens of thousands of convalescent plasma donors who rolled up their sleeves to share their health and provide hope to patients and their families during an uncertain time.

Q: I’ve heard claims that the Red Cross refuses to accept convalescent plasma from individuals who have received a COVID-19 vaccine because it wipes out the antibodies. Is this true?

A: There are claims circulating that incorrectly state that the Red Cross will not accept convalescent plasma donations from those who have received the COVID-19 vaccine because “the vaccine wipes out those antibodies making the convalescent plasma ineffective in treating other COVID-19 patients.” This is not accurate.

Due to the decline in hospital demand and because the Red Cross and our industry partners have been able to build a sufficient supply of convalescent plasma to meet the foreseeable needs of COVID-19 patients the Red Cross stopped collecting convalescent plasma completely on June 14.
