	Dear List Members,
			K. Weber kindly posted a message regarding ongoing 
research on stealth virus encephalopathy as a cause of chronic fatigue 
syndrome. The work is described at the Web site 

			A virus repeatedly isolated from a CFS patient 
has a high degree of sequence homology to African green monkey 
cytomegalovirus. Primary kidney cell cultures from these animals are used 
to produce live polio virus vaccines. It has been known but never 
publically disclosed that the monkeys used in polio vaccine production 
harbor cytomegalovirus and that this type of virus can be grown out from 
monkey kidney cultures. It was also known, since I did the studies while 
working at the FDA, that polio vaccines contained DNA which could not 
hybridize to the DNA from normal monkey cells.

		An important issue concerning polio vaccines is, 
therefore, not whether they were effective in diminishing the incidence 
of polio, but whether they inadvertently introduced pathogenic 
monkey-derived viruses into humans. Although this important topic has 
been presented at both an FDA sponsored vaccine safety meeting and an 
Institute of Medicine Workshop on vaccine safety, neither FDA nor CDC has 
been willing to engage in any meaningful dialogue.   

		Additional information can be found on the Web site.
