This just out in a May 2010 BVA decision. It doesn’t matter which one- he lost. Listen to his evidence:In support of his claim, the Veteran submitted an excerpt of  an article indicating that “[a] research project headed by  Lawrence Deyton, MSPH, MD, the Director of Aids/Hepatitis at  the United States Department of Veterans Affairs in  Washington, D.C., said in part ‘Anyone who had inoculations  with the jet injector is at risk of having hepatitis C and  should be tested.’  Research indicates that the hepatitis C  virus still exists on medical instruments after cleaning with  many solutions.”:

But In a February 2010 opinion, a VA hepatologist opined, after  reviewing the Veteran’s claims file, that it was less likely  than not that the Veteran contracted hepatitis C as a result  of the in-service jet injector inoculations.  The opining  physician reasoned that the Veteran had multiple sources of  risk infection, including sources other than the  inoculations.  While it was possible in theory that the  immunizations could have transferred hepatitis C to the  Veteran, given his admitted history of cocaine use, it would  be impossible to show that the immunizations were the more  likely cause.  If he had no other potential causes  documented, and had not lived a life style such as alcohol  dependence, which in itself was a marker of possible  exposure, it might be more likely that he contracted the  virus as a result of the in-service immunizations.  However,  given his history of exposure by known sources, jet  immunization was a remote possibility of the cause of the  injection.  The physician noted, with significance, that  there were no proven cases of jet immunization causing  hepatitis C.

Witness the alcohol abuse as a viable vector for HCV. Would someone enlighten me as to what part of getting drunk is a HCV risk factor? Passing out in a puddle of infected blood? I say we add alien abduction to the list of risks. That is more believable.
