Thimerosal: From the 1930s to 2011

Thimersol DOES have neurotoxic effects on infants and toddlers! That’s a scientifically derived conclusion that’s been viciously kept from health consumers probably due to not wanting to have to scrape egg off the universal face of Big Pharma vaccine manufacturers, the medical professions, and government health agencies. Or, is there a more sinister reason? You be the judge after considering Dr. F. Edward Yazbak’s exceptional review of the literature regarding Thimerosal and vaccines at (…)

There are three parts to this incomparable report regarding Thimerosal that every healthcare professional, federal, state, and local health agencies personnel should read to get the down and dirty facts about what’s been going on under their closed eyes regarding a neurotoxin they are pushing with such vigor as to make one wonder why. The following is taken from Dr. Yazbak’s report that you ought to read in order to connect the dots back to the very beginning of the Thimerosal issue.

Doctor Yazbak says, “In all, there were 64 PubMed listings related in some way to Thimerosal from the 1930s to 1999, an average of 1 publication a year.”

Furthermore, “Over 300 articles on issues related to Thimerosal in vaccines were written, peer-reviewed and published in the last 12 years. On average, there was 1 publication per year from the late 1930’s to 1999 vs. more than 25 publications per year from 1999 to April 2011.”

“Given the fact that pediatric vaccines have been recommended and used ‘since the 1930’s’, the paucity of research for decades into a key vaccine ingredient is at best shocking and at worst damning.”

In his article, Yazbak cites exceptional resources, but two has data that cannot be misconstrued. Keep in mind that the U.S. Army uses hair testing, so it definitely is no unscientific woo-woo stuff! Following are two hair test results studies regarding breast fed infants who were vaccinated with Thimerosal-containing vaccines.

Hair mercury in breast-fed infants exposed to thimerosal-preserved vaccines. Marques RC, Dórea JG, Fonseca MF, Bastos WR, Malm O. Eur J Pediatr. 2007 Sep;166(9):935-41. Epub 2007 Jan 20. PMID: 17237965 (

“…the Hg exposure corrected for body weight at the day of immunization was much higher from thimerosal- EtHg (5.7 to 11.3 microgHg/kg b.w.) than from breastfeeding (0.266 microgHg/kg b.w.). While mothers showed a relative decrease (-57%) in total hair-Hg during the 6 months lactation there was substantial increase in the infant’s hair-Hg (446%). We speculate that dose and parenteral mode of thimerosal-EtHg exposure modulated the relative increase in hair-Hg of breast-fed infants at 6 months of age.”

Neonate exposure to thimerosal mercury from hepatitis B vaccines. Dórea JG, Marques RC, Brandão KG. Am J Perinatol. 2009 Aug;26(7):523-7. Epub 2009 Mar 12. PMID:19283656 (

“Infant exposure to ethylmercury (EtHg) has not only increased but is starting earlier as a result of the current immunization schedule that uses thimerosal-containing vaccines (TCVs). Although vaccination schedule varies considerably between countries, infants in less-developed countries continue to be exposed to EtHg derived from more affordable TCVs. We studied the exposure of newborns to EtHg from hepatitis B vaccines; hospital records (21,685) were summarized for the years 2001 to 2005 regarding date of birth, vaccination date, and birth weight. Most of the vaccinations occurred in the first 24 hours postdelivery; over the 5 years, there was an increase in vaccinations within hours of birth (same day), from 7.4% (2001) to 87.8% (2005). Nearly 94.6% of infants are now being vaccinated within the first 24 hours. Range of mercury exposure spread from 4.2 to 21.1 microg mercury/kg body weight for those receiving TCVs with the highest thimerosal concentration; these exposure levels are conservative for 2% of children receiving vaccines within 2 to 3 postnatal days, when they are still going through physiological postnatal weight loss. Because of the particular timing (transitioning from in utero to ex utero metabolism) and specific aspects of exposure (i.e., parenteral mode, bypassing gastroenteric barriers) and dose (related to vaccine manufacturer and with variation in birth weight), this study reveals critical issues that can modulate toxicokinetics and toxicodynamics of organomercurials in neonates.”

Did you note in the above that Nearly 94.6% of infants are now being vaccinated within the first 24 hour? That truly is outrageous, in my opinion, since Hepatitis B is transmitted via contaminated street drug needles and sexual intercourse. Newborn babies have not been exposed to either unless the baby’s mother has Hepatitis B.

After careful review by Dr. Yazbak regarding Dr. Jose Dórea’s study dealing with Thimerosal and vaccines out of Universidade de Brasilia, one of Brazil’s largest and most prestigious universities, “Integrating Experimental (In Vitro and In Vivo) Neurotoxicity Studies of Low-dose Thimerosal Relevant to Vaccines”, he says,

“Thimerosal in concentrations such as those presently in pediatric vaccines still used in many countries “is toxic to cultured human brain cells and to laboratory animals”

The present use of TCVs in developing countries “is counterintuitive to global efforts to lower Hg exposure and to ban Hg in medical products”

The continued use of TCVs requires evaluation of “a sufficiently nontoxic level of ethylmercury compatible with repeated exposure (co-occuring with adjuvant –Al) during early life.” (

The last sentence by Dr. Yazbak quoting the Dόrea review is most revealing since the interaction of aluminum with TCVs has not been addressed by the U.S. HHS, CDC, FDA or even the pharmaceutical vaccine manufacturers, which doesn’t make sense since both are toxins and normally have neurotoxic effects—at least according to biochemistry.

Dr. Yazbak states, “The author ended by appropriately pointing out that more studies were urgently needed because ‘despite demonstrable toxicity of Ethyl Mercury’, Thimerosal-containing vaccines were still being used in increasing quantities in developing countries even though real concerns about pregnant women and newborns receiving such vaccines existed.”

In February 2004, Dr. Yazbak questioned the CDC’s action, “Why the CDC ever funded epidemiological studies in Denmark where the pediatric vaccination schedule was different from that of the United States, where fewer vaccines were administered and where Thimerosal had been banned for a decade are questions that just beg to be answered.” Note that Denmark had banned Thimerosal for ten years before 2004!

Dr. Yazbak contends, “Regardless, what no one knew or imagined was that the CDC was also clandestinely ghost-writing, in a fashion, a review of Thimerosal by a US academician and that the IOM committee wanted to see that review before the February 2004 hearing.” And, Dr. Yazbak includes the letters from July 2003 to December 2003 corroborating how that review would be written. They were obtained from CDC via the Freedom of Information Act. Interesting?

Dr. Yazbak’s conclusions are:

“The IOM Immunization Safety Review Committee was influenced by the CDC before and during its February 9, 2004 meeting. The committee’s decision concerning Thimerosal and autism was flawed, ill-advised and based on biased epidemiological studies, several of which funded or instigated by the CDC and its National Immunization Program. Moreover its timing was apparently designed to avoid imminent studies which could have demonstrated a connection between vaccines and autism.”

And, “Countries that have the means to buy preservative-free vaccines should ignore the WHO recommendations and do so. The minute added cost of preservative-free single dose vaccines is negligible when compared to the financial and human cost of autism.”

Furthermore, “HHS should order the Institute of Medicine to create a new Vaccine Safety Review Committee with a new chairperson.”

While, “The National Vaccine Injury Compensation Program should be requested to ignore the IOM recommendations and to review the presently available information on Thimerosal.”

Plus, “The preponderance of available evidence strongly suggests that Thimerosal containing vaccines could have indeed caused neurological and developmental complications in genetically predisposed infants and children.”

You are so RIGHT, Dr. Yazbak in saying, “In fact, the preponderance of evidence seems overwhelming!”

Thank you so very much, Dr. Yazbak, for this exceptional research and Vaccination News for publishing this incriminating report. I hope my condensation of part 3 will entice researchers, health professionals and agencies, and health consumers to read it in its entirety because there is an awful lot to learn. I applaud your efforts.
