Making sense of epidemiological studies of young children exposed to thimerosal in vaccines

Abstract

To compare epidemiological studies dealing with neurological issues (compatible with Hg toxicity) linked to exposing newborns and infants to intramuscular doses of preservative-Hg resulting from vaccination with thimerosal-containing vaccines (TCV). Major databases were searched for studies that addressed neurodevelopment outcomes other than autism. Eight studies were identified and compared. Information extracted from the studies done in the USA, the UK, and Italy is important in understanding the complex interplay of variables but insufficient to establish non-toxicity for infants and young children still receiving TCV: a) there is ambiguity in some studies reporting neurodevelopment outcomes that seem to depend on confounding variables; b) the risk of neurotoxicity due to low doses of thimerosal is plausible at least for susceptible infants; c) there is a need to address these issues in less developed countries still using TCV in pregnant mothers, newborns, and young children. Since the use of TCV is still inevitable in many countries, this increases the need to protect vulnerable infants and promote actions that strengthen neurodevelopment. Developing countries should intensify campaigns that include breastfeeding among eff...Continue Reading

Cellular Immunometabolism

Immunometabolism involves not only the way metabolites are digested by the immune system, but the way in which they can alter the pathway of the immune system. These responses occur in day-to-day healthy cell functioning, but can result in diseases, such as autoimmune disorders. Discover the latest research on cellular immunometabolism here.

Avian Influenza: Innate Immune Adjuvant

Adjuvants systems that are added to vaccines against avian influenza have be explored to enhance the innate immune system response against the virus. Here is the latest research on avian influenza and the innate immune adjuvant.

Autism

Autism spectrum disorder is associated with challenges with social skills, repetitive behaviors, and often accompanied by sensory sensitivities and medical issues. Here is the latest research on autism.

Avian Influenza: Innate Immune Adjuvant (ASM)

Adjuvants systems that are added to vaccines against avian influenza have be explored to enhance the innate immune system response against the virus. Here is the latest research on avian influenza and the innate immune adjuvant.

Autism: Treatment Targets

The absence of effective treatments for autism are due to the high clinical and genetic heterogeneity between affected individuals, restricted knowledge of the underlying pathophysiological mechanisms, and the lack of reliable diagnostic biomarkers. Identification of more homogenous biological subgroups is therefore essential for the development of novel treatments based on the molecular mechanisms underpinning autism and autism spectrum disorders.
