The question of whether vaccines cause autism has been studied extensively. The scientific evidence is clear: vaccines do not cause autism. Here are the key facts every parent should know.

The Research Is Extensive

• A 2019 Danish study of over 650,000 children found no increased risk from the MMR vaccine
• A 2014 meta-analysis of over 1.2 million children found no vaccine-autism link
• The Institute of Medicine reviewed over 1,000 studies and confirmed vaccine safety
• Vaccinated and unvaccinated children show identical autism rates

The Original Study Was Fraudulent

The hypothesis originated from a 1998 study by Andrew Wakefield. Investigation revealed manipulated data and undisclosed financial conflicts. The Lancet retracted the paper, and Wakefield lost his medical license.

Thimerosal and Ingredients

Thimerosal was removed from nearly all childhood vaccines by 2001 as a precaution, yet autism rates continued to rise, further disproving any connection.

What Actually Causes Autism

Autism is primarily genetic, with heritability estimates of 60-90%. Environmental factors during pregnancy may also play a role. For evidence-based support, ABA therapy helps autistic individuals develop skills. Contact Treetop ABA Therapy to learn more.
