"As part of the FDAMA review, the FDA evaluated the amount of mercury an infant might receive in the form of ethylmercury from vaccines under the U.S. recommended childhood immunization schedule and compared these levels with existing guidelines for exposure to methylmercury, as there are no existing guidelines for ethylmercury, the metabolite of thimerosal. At the time of this review in 1999, the maximum cumulative exposure to mercury from vaccines in the recommended childhood immunization schedule was within acceptable limits for the methylmercury exposure guidelines set by FDA, ATSDR, and WHO. However, depending on the vaccine formulations used and the weight of the infant, some infants could have been exposed to cumulative levels of mercury during the first six months of life that exceeded EPA recommended guidelines for safe intake of methylmercury.

As a precautionary measure, the Public Health Service (including the FDA, National Institutes of Health (NIH), Center for Disease Control and Prevention (CDC) and Health Resources and Services Administration (HRSA) and the American Academy of Pediatrics issued two Joint Statements, urging vaccine manufacturers to reduce or eliminate thimerosal in vaccines as soon as possible (CDC 1999) and (CDC 2000). The U.S. Public Health Service agencies have collaborated with various investigators to initiate further studies to better understand any possible health effects from exposure to thimerosal in vaccines."

I never said it was linked to any disease. I said the FDA pulled it because of potential build-up.

I just quoted you two paragraphs from the FDA. In order for me (or my wife) to explain this properly to someone afraid of vaccines, I have to explain enough organic chemistry to point out that ethyl mercury and methyl mercury aren't the same... and then they're likely to point out that while polypropylene glycol and polyethylene glycol aren't the same, either, both of them are banned in Scandinavia as food additives but only one of them is in the US.

That's not denialism. That's people - apparently, like you - who think that anyone who doesn't have an organic chemistry degree shouldn't be allowed to point out that there are contradictions in behavior of the very organizations that are supposed to protect them.

"These people" are likely your friends and neighbors. They'd likely turn to you for advice. Your advice, as I've pointed out, is "STFU&GTFO."

And that's why you never change their mind.
