For many years, individuals who lived in Europe during the 1980s faced blood donation restrictions in the United States. These precautions were implemented to safeguard the blood supply but have since been updated, reflecting advancements in scientific understanding and risk assessment.
Understanding the Deferral
Past deferral policies stemmed from concerns about variant Creutzfeldt-Jakob Disease (vCJD), also known as “Mad Cow Disease.” This rare, fatal neurological condition was first identified in the United Kingdom, with most human cases linked to consuming contaminated beef during a UK epidemic in the 1980s and 1990s.
The deferral was a precautionary measure due to vCJD’s long incubation period and the lack of an approved blood screening test. Although transmission risk through blood was largely theoretical, a few UK cases suggested transfusion transmission, leading health authorities to implement broad deferrals.
Who is Affected by the Rules
The U.S. Food and Drug Administration (FDA) significantly updated its blood donation guidelines for vCJD exposure. As of May 2022, the FDA removed deferral recommendations for individuals who spent time in certain European countries, making many previously ineligible donors now eligible.
Specifically, deferrals for time spent in the United Kingdom (including England, Northern Ireland, Scotland, Wales, the Isle of Man, the Channel Islands, Gibraltar, or the Falkland Islands) from 1980-1996 have been removed. Individuals who spent time in France and Ireland from 1980-2001 are also generally no longer deferred based on that travel history. Additionally, the deferral for receiving a blood transfusion in the UK, France, or Ireland from 1980 to the present has been lifted.
Previously deferred individuals should contact their local blood center, as some may require a reinstatement process. Permanent deferrals still apply for those diagnosed with vCJD, Creutzfeldt-Jakob Disease (CJD), or other transmissible spongiform encephalopathies. Deferrals also remain for individuals with a blood relative diagnosed with familial prion disease or who received certain human tissue transplants, such as cadaveric pituitary human growth hormone or dura mater grafts.
Protecting the Blood Supply
Ensuring blood supply safety is a top priority for health authorities. Past vCJD deferral policies were part of a comprehensive strategy to minimize theoretical risk to transfusion recipients. These regulations are designed to maintain a safe and adequate blood supply through careful donor screening.
The FDA’s recent lifting of European travel deferrals reflects a risk reassessment, concluding vCJD transmission risk by blood components is now negligible. This decision was based on extensive research and ongoing surveillance. Blood collection organizations continue rigorous testing and screening processes for all potential donors, including detailed health questionnaires and physical assessments.
How to Still Contribute
Individuals unable to donate blood due to current eligibility criteria can still make a meaningful difference. One way to contribute is by encouraging eligible friends, family, and colleagues to donate. Spreading awareness about the ongoing need for blood and the donation process can inspire others.
Volunteering at blood drives or donation centers offers direct support, ensuring smooth operations and a positive donor experience. Financial donations to blood organizations also provide essential resources, supporting research, operational costs, and community outreach. These alternative forms of support are valuable contributions to public health.
