Thimerosal in Vaccines May Increase Serotonin Neurons in the Brain





MCS America

Lourdes Salvador's Column

...Co-founder of MCS America discusses the latest Multiple Chemical Sensitivity issues.









Lourdes Salvador is the founder of MCS America, a science writer, and a social advocate for the greater awareness of environmental contamination, human toxicology, and propagation of multiple chemical sensitivity (MCS) as a disorder of organic biological origin induced by toxic environmental insults.

Thimerosal in Vaccines May Increase Serotonin Neurons in the BrainThimerosal in Vaccines May Increase Serotonin Neurons in the Brain

by Lourdes Salvador



Embryonic exposure to thimerosal, a vaccine preservative, affects early development, say researchers Ida-Eto and colleagues.


Brain toxicity as a result of organomercury compounds is well known. Thimerosal is an organomercury compound which is still widely used as a pediatric vaccine preservative.


Ida-Eto and colleagues found that when pregnant rats are given thimerosal containing injections, it produces a predictable and dramatic increase in serotonergic neurons.


Too much serotonin is linked to agitation or restlessness, diarrhea, fast heart beat, hallucinations, increased body temperature, dilated pupils, twitching, trembling, loss of coordination, nausea, overactive reflexes, rapid changes in blood pressure, and vomiting. If serotonin increases too much, it can be life threatening.


Serotonin is involved in the regulation of several brain processes such as mood, sleep, appetite, memory, and perception. In fact, many other brain and body functions are affected by serotonin, including the heart, muscles, and endocrine systems.


These effects may or may not be reversible.


People who opt to take a gamble on vaccines may choose a thimerosal free version by request. The thimerosal free versions generally cost a bit more, however the loss of quality of life and financial costs to treat lifelong brain disorders that may result from thimerosal exposure is innumerably greater.



Ida-Eto M, Oyabu A, Ohkawara T, Tashiro Y, Narita N, Narita M. Embryonic exposure to thimerosal, an organomercury compound, causes abnormal early development of serotonergic neurons. Neurosci Lett. 2011 Jun 6. PMID:  21669256
