FOIA: Peter Patriarca – Asleep at the Switch Email

Peter Patriarca, an FDA employee, admitted back in 1999, in a confidential e-mail obtained through FOIA, that, “… the greatest point of vulnerability on this issue is that the systematic review of thimerosal in vaccines by the FDA could have been done years ago and on an ongoing basis as the childhood immunization schedule became more complex.  The calculations done by FDA are not complex. I’m not sure if there will be an easy way out of the potential perception that the FDA, CDC and immunization policy bodies may have been “asleep at the switch” re: thimerosal until now”.

Thimerosal’s Nomination to the National Toxicology Program

In 2001, Thimerosal was nominated to the NTP for further study to assess gaps in knowledge regarding toxicokinetics and the potential for neurodevelopmental toxicity. These gaps included comparative toxicity of ethyl- and methylmercury, the metabolism and elimination of ethylmercury compared with methylmercury, the effect of intermittent intramuscular doses of thimerosal from vaccines compared with chronic low dose oral exposure to methylmercury, and the susceptibility of the infant compared with the fetus to adverse effects from organic mercurials. In order to provide a more complete assessment of the toxicity of thimerosal during the critical period of neurodevelopment, well-designed studies were needed to address these gaps in knowledge in appropriate animal model(s). Many of these studies were never done and thimerosal’s nomination was rejected.

Thimerosal is recognized as a reproductive toxicant in the state of California

Outlined below is a review by the California Environment Protection Agency regarding the use of thimerosal as it relates to Proposition 65 in California. Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted in November 1986. The proposition protects the state’s drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals. Proposition 65 requires the state to maintain and update a list of chemicals known to the state to cause cancer or reproductive toxicity.

Thimerosal – MSDS

Exposure to methylmercury most commonly occurs when people eat kinds of fish and shellfish that have high levels of methylmercury in their tissues. Almost all people have at least small amounts of methylmercury in their bodies, reflecting the widespread presence of methylmercury in the environment. U.S. Centers for Disease Control and Prevention (CDC) data show that most people have blood mercury levels below levels associated with possible health effects. Methylmercury, however, is a powerful neurotoxin, and people exposed to high levels may experience adverse health effects. If you are concerned about your exposure to methylmercury, you should consult your physician.

My name is Walter Orenstein. I’m Director of the National Immunization Program at CDC and I want to thank all of you for coming here and taking time out of your very busy schedules to spend the next day and a half with us. Not only do we thank you for taking time out, but for taking the time out on such short notice, and also putting up with what I gather those of us who are townies here didn’t realize, but apparently the biggest meeting in Atlanta which has taken up all the hotel space and all of the cars, so I think many of you have had to take taxis here. We appreciate you putting up with this, but at least we did arrange the weather nicely and you can look out occasionally and see some beautiful trees.
