I lived in Paris for five months in 1987, the year Mad Cow Disease (Creutzfeldt-Jakob disease) ravaged the UK and Europe. I returned to Canada in the summer of the same year and was told that I would not be allowed to donate blood because I was deemed a risk.
I returned to the blood donor clinic every year or so to be told the same thing again and again. My school frequently had blood donor clinics which I joined, to no avail, decade after decade, until I received an email a few weeks ago: Following updated guidance from the Food and Drug Administration, New York Blood Center announced revised eligibility regarding Creutzfeldt-Jakob disease (also known as Mad Cow disease, CJD or vCJD).
And so, yes, it took the United States government 35 years to allow me to give blood again. Is there really anybody in charge of anything?
