I've been very interested in reading the cross-over threads discussing XMRV, autism, vaccines etc. Many on this forum have commented on having had autism like symptoms pre illness. Looking back, I was a happy well adjusted child up to late primary school stage (no sexual or other abuse that I can recall) but from the age of 10 or 11, I became steadily more socially phobic with a few good friends but hating crowds and strangers. I also have the face recognition problem. Nothing too serious but certainly suggestive of the autism/aspergers spectrum. One thing I do recall from later primary school age is the dreaded 'six needles/BCG' vaccination against TB. BCG is a live 'attenuated' virus. After doing a little web-surfing it appears that severe reactions to the vaccination (reported) are rare but involve the lymph glands and there are reports of post vaccination autism with the BCG and polio vaccines. This link is an anecdote, but interesting : http://www.whale.to/v/bcg2.html There is much more robust data available and sites dedicated to post vaccine autism : http://www.ageofautism.com/2008/06/vaccine-injurie.html I can't help wondering if early childhood vaccinations 'set us up' for developing ME?
