I know in the beginning some Gulf War Vets were being diagnosed with CFS and Fibromyalgia. There's also the issue of the sealed records in the UK. Makes you wonder a bit. There are so many things that go on that we just don't know about or it's found out later to be a problem. Examples: Celebrex (later tied to heart associated deaths), Bisphenol A in plastics (a hormone disruptor which has been in baby bottles, pacifiers and most plastic containers for 20 or so years, in process of being banned), melamine in dog food, and later found in baby formula, and an additive in most processed food. And various other products that the FDA approves and the CDC doesn't always followup on when problems are found. Oh and let's not forget retroviruses and pig DNA in vaccines. Aw noone will ever know, at least not for 30 or 40 or 50 years from now.
