I am kind of new here but when i saw the post on flu shots I had to respond. I developed my CFIDS 13 years ago after getting a flu shot not long after gettin Hep.B vaccinations. I don't know which started the path to CFIDS and could have been the combo. but wanted to share my acct. I was a teacher of sp. ed. and encouraged to get Hep. B. vac. so did-just 2 of them. When I got the flu shot several weeks later I came down with a 104 temp for a month and tested positive for Epstein Barr, Hepatitis, Herpes 6 and several other viruses. Anyway, was very sick for several years and got diagnosed with CFIDS. Have been disabled and not well ever since. Hope this will be of help to someone.
