According to a study by the International Journal of Environmental Research and Public Health, published January 23rd, 2015, safety levels of ethylmercury and aluminum in vaccines have never been established.
“Despite their long use as active agents of medicines and fungicides, the safety levels of these substances have never been determined, either for animals or for adult humans—much less for fetuses, newborns, infants, and children.” (1)
“Rigorous and replicable studies (in different animal species) have shown evidence of EtHg (ethylmercury), and of Al (aluminum) toxicities. More research attention has been given to EtHg and findings have showed a solid link with neurotoxic effects in humans; however, the potential synergic effect of both toxic agents has not been properly studied. Therefore, early life exposure to both EtHg and Al deserves due consideration.” (1)
