FDA changes guidelines for blood donors
The FDA recently made changes to several guidelines during the COVID-19 pandemic, which may offer additional opportunities for you to give blood if you were previously unable to donate.
Military members and their families
The largest impact in South Texas, with its large military population, is a change to guidelines involving service members and their families. Many members of the U.S. military, their families and civilian contractors stationed in Europe during the 1980s and 1990s are now eligible to donate. They previously were deferred from giving blood following the outbreak of “mad cow disease,” or Creutzfeldt-Jakob disease.
The FDA also reduced the deferral or waiting period to give blood to 3 months for many potential donors who previously had to wait 12 months to donate. A complete list of the guideline changes is included below.
Have you been told you're ineligible to give blood?

Why the changes?
The Food and Drug Administration’s changes to blood donation guidelines were the result of recent studies and data showing the criteria can be modified without compromising the safety of the blood supply. The changes will increase the number of people able to give blood.
The FDA is continuing to evaluate eligibility guidelines and you can learn more about the changes on the FDA website.
What is new for people who were active-duty military, civilian military employees and their families in Europe?
Until these changes, if you were stationed for more than six months in Germany, Belgium, the Netherlands from 1980-90, or Greece, Turkey, Spain, Portugal or Italy from 1980-96, you could not donate blood. You now are eligible to give.
What about other countries in Europe?
Anyone who spent five years or more in France or Ireland from 1980-2001 will not be able to give. If you received a blood transfusion in the United Kingdom, Ireland or France since 1980, or lived in the United Kingdom for more than three months from 1980-96, you still will not be able to donate.
Why were these rules in place?
The guidance affecting military personnel was the result of the outbreak in Europe of variant Creutzfeldt-Jakob disease (vCJD), commonly referred to as “mad cow disease.”
What else has changed?
You now will be able to donate three months after the following (the deferral period previously had been 12 months):
- Travel to areas with a risk of malaria in the last three years
- A man who had sex with another man
- A blood transfusion
- Organ, tissue or bone marrow transplant
- Bone or skin graft
- Contact with someone else’s blood
- An accidental needle-stick
- Sexual contact with anyone who has HIV/AIDS or has a had a positive test for the HIV/AIDS virus
- Sexual contact with a prostitute or anyone else who takes money or drugs for sex
- Sexual contact with anyone who has ever used needles to take drugs or steroids, or anything not prescribed by their doctor
- Female donors who have had sexual contact with a male who had sexual contact with another male
- A tattoo from a non-licensed facility (there is no waiting period if tattoos were done in a state-regulated establishment and have fully healed)
- An ear or body piercing without single-use equipment (there is no waiting period if piercings were done with a single-use device, as long as they have healed)
- Treatment for syphilis or gonorrhea
You now will be able to donate three months after the following (the deferral previously had been indefinite):
- Use of needles to take drugs, steroid or anything else not prescribed by your doctor
- Accepting money, drugs or other payment for sex
