Which statement about Thimerosal and Autism Spectrum Disorder is correct?

Which statement about Thimerosal and Autism Spectrum Disorder is correct?

• A. Thimerosal is a major cause of ASD
• B. Thimerosal is safe and present in all vaccines
• C. Thimerosal should be avoided entirely to prevent ASD
• D. Thimerosal doesn't cause ASD and is no longer in most vaccines given to children

Answer: (D)

Thimerosal doesn't cause autism and is no longer in most vaccines given to children. A large body of research has repeatedly looked for any link between thimerosal exposure from vaccines and autism spectrum disorder and has consistently found no causal relationship. This matters because autism has a complex range of factors, but vaccines with and without thimerosal do not increase ASD risk. In response to safety concerns, thimerosal was removed or reduced to trace amounts in virtually all routine childhood vaccines, with only limited use in some multi-dose influenza vaccines. Therefore, the statement reflects the evidence: no link to ASD and minimal presence in vaccines given to children. The other statements contradict the evidence or current practice, which is why they’re not correct.
