TO ALL, I have heard that the US Red Cross refused to accept blood from any donor that has lived in England. Does any one know if this is true? If it is true,there is much more of a time bomb here than most of us know about.Johnray1

Yes, it's true, Johnray - or it was when last I checked. I can't donate, and my US born wife can't either because she lived in London during the outbreak. We tried to donate my son's cord blood after he was born in a California hospital back in 2001 and met with the same response.

To date here in the UK, there have been 67 identified recipients of blood from donors who later developed vCJD, 3 of these recipients then went on to develop the disease pretty soon after transfusion, and 1 additional case was asymptomatic, (died of unrelated illness but was found at postmortem to have prion induced aggregates).
Research into the " silent carriers of vCJD" is well funded here, and the surveillance programme is pretty good. Endoscopy and neurological instruments as well as transplants, blood products etc are all tracked because of the risk. A huge study is underway testing 200,000 people anonymously. There are treatments which may be effective if they can catch disease early before misfolded proteins accumulate in brain. vCJD appears to need very intact lymphoid tissue to accumulate and spread onward, this intact system begins to break down by the time we are in our 30s, perhaps why young people were the predominant victims with an average age of 26 at diagnosis. However here is the thing, the recipients of the contaminated blood that developed vCJD were older and incubation time shorter. The number is low so difficult to draw conclusions, but it may suggest that transmission of vCJD via contaminated beef is different than transmission from blood products. Animal studies conclude this, with blood products perhaps offering a more efficient transfers of the prion. ( big worry i.e.even if those contaminated by beef don't develop symptoms, these silent carriers may be efficient spreaders through blood products, shared endoscopes, surgical equipment etc) hence the caution of UK blood products). Here in the UK, after an incident at work where I was exposed to Hep B, I got a Ig vaccination post exposure for HepB which is a blood product. It was made from pooled US volunteers, as the UK stuff has all been destroyed due to possible vCJD contamination. So seems we don't trust some of our own products. So whether we are sitting on a giant time bomb, or a slight ripple we don't know. I do know here in UK the surveillance continues. |

From 2001
The Center for Biologics Evaluation and Research (CBER) and the U.S. Food and Drug Administration (FDA) learned earlier this year that some vaccines were manufactured with bovine–derived materials obtained from countries where bovine spongiform encephalopathy (BSE; mad cow disease) is prevalent or where a substantial risk for BSE exists. Creutzfeldt-Jakob disease (vCJD), the human equivalent of BSE, has been attributed to, among other possibilities, eating beef products from cattle infected with the prion agent of BSE. Although there is no evidence to date that cases of vCJD are related to the use of vaccines, interestingly a vaccine lot was withdrawn because of being exposed to FBS from the country where high risk for this prion disease exists. The study summarised in the first paragraph will be presented in the 101st ASM Meeting in Orlando in May 21, 2001 (1.00-2.30pm). The Kuopio team’s message to the scientific society in this presentation will be: More research is needed to understand nanobacteria and their role in human and animal diseases. To err on the side of safety is no vice; just as prions and viruses were viewed with scepticism before they were completely characterised, so concepts of nanobacteria (and the scientists who study them) will be knocked around until more is known about NB. Vaccines should be regarded as safe and essential to human health in the modern age until they are proven otherwise |

http://www.theguardian.com/world/2015/feb/13/canada-confirms-mad-cow-disease-case-bse
confirmed its first case of mad cow disease since 2011 on Friday but expressed confidence the discovery would not hit a beef export sector worth C$2bn ($1.6bn) a year. The Canadian Food Inspection Agency (CFIA) said no part of the animal, a beef cow from Alberta, had reached the human food or animal feed systems. Mad cow is formally known as bovine spongiform encephalopathy (BSE), a progressive, fatal neurological disease. “The CFIA is seeking to confirm the age of the animal, its history and how it became infected. The investigation will focus in on the feed supplied to this animal during the first year of its life,” the agency said. |

A codicil to the former conversation, I have found a vegan source of B12 worth having. It is not an insignificant amount. It is not an analogue which actually depletes your b12. It is not from a lab - you can grow it at home. 1.5 microgrammes is the RDA for most adults although the elderly, growing and pregnant have an RDA of 2.5 mcg That amounts to ½ -1 TEASPOONFUL!!! |
