Thanks for looking that up for me. I grew up in south east Kentucky. Harlan, Kentucky.
I found several papers that have been published about the Hepatitis A vacine the footnote on the vacine that talks about the Adverse events following the administration of the vacine reads as follows
Serious Adverse Events
An estimated 1.3 million persons in Europe and Asia were vaccinated with HAVRIX before the vaccine's licensure in the United States in 1995. Reports of serious adverse events, without regard to causality, received by the vaccine manufacturer included anaphylaxis, Guillain-Barré syndrome, brachial plexus neuropathy, transverse myelitis, multiple sclerosis, encephalopathy, and erythema multiforme (SmithKline Beecham Biologicals, unpublished data, 1995). The majority of these events occurred among adults, and approximately one third occurred among persons receiving other vaccines concurrently. For serious adverse events for which background incidence data can be estimated (e.g., Guillain-Barré syndrome and brachial plexus neuropathy), rates for vaccine recipients were not higher than would be expected for an unvaccinated population (CDC, unpublished data, 1995).
With further reading I found this article ... Presence of Oligoclonal T Cells in Cerebrospinal Fluid of a Child with Multiphasic Disseminated Encephalomyelitis following Hepatitis A Virus Infection
http://cdli.asm.org/cgi/content/full/8/5/984
as you can see the article is full of medical jargon and stuff reserved for those with an education... I have to admit I didn't read the whole article, but it talks of known climate regions which predispose one to the eventual contraction of MS and how other articles have sited an increased number of reported childhood exposure to the hepititis's and a possible link therein
Interesting at least...
Where did you grow up?
