Sorry, I know that can be scary. I've had nurses get irritated by my thimerosol questions and insistance on seeing the ingredients, because I was scared of it.

Thimersol can be harmful to anyone because of the mercury in it. But you needed the vaccination at the time, so there's not much that you could have done. I think that as Boldylocks said, continuing chelation would be a good idea. I don't have any advice on what type of chelation to do, but hopefully some others will chime in on this. Do you have a doctor that is currently treating you for mercury? If so, I would check in with him/her and see what they advise.

Take care,
