July 20, 2022 – Thanks to new guidelines from the FDA, Oklahoma Blood Institute hopes to welcome back thousands of deferred blood donors who have been unable to donate blood for the last 20 years.


Previously, potential blood donors who had spent time in Europe, including many military families stationed abroad, were deferred from donating blood because of the theoretical risk of variant Creutzfeldt-Jakob disease (vCJD), commonly known as “mad cow disease,” which is a rare disease of the central nervous system.


Based on updated evidence, the FDA’s new guidance removes the deferral recommendations associated with risk of vCJD for time spent in the United Kingdom from 1980-1996; time spent in France and Ireland from 1980-2001; and receipt of a blood transfusion in the U.K., France or Ireland from 1980-present.


In 2020, the FDA removed several other European countries from the deferral list. These new changes remove the remaining countries, effectively lifting the entire deferral.


Those unsure if this eligibility guidance affects them are encouraged to call the OBI eligibility hotline at 888-308-3924.


“We are grateful to see the FDA use the latest scientific data to adjust deferral rules, allowing us to welcome back many donors, and invite in countless others who have not attempted to donate due to the restrictions,” said John Armitage, M.D., president and CEO of Oklahoma Blood Institute. “This move will help expand our donor pool, as there is an ongoing need for blood donation, especially during the summer months.”


OBI asks the community to respond by giving blood* today. Donors can make appointments and find donation locations at or by calling 877-340-8777. Walk-ins are welcome.


Oklahoma Blood Institute is the sixth-largest independent blood center in the nation, providing more than 90 percent of Oklahoma’s blood supply to over 160 hospitals and medical facilities.
