I didn't see a poll for this before, and it seems like a useful one. I only recently remembered that I had gotten a tetanus booster not too long before developing a Type IV food sensitivity and subsequent ME/CFS. Maybe I'd have developed the immune system problem from some other trigger--such as a cold virus--at that time of my life, but the vaccination certainly seems suspicious in timing.
If you developed some immune system hypersensitivity soon after a vaccination, and then developed ME/CFS, vote yes, and maybe post a qualifier explaining it.
