Is there any link between receiving a vaccine and developing autism?

No, vaccines do not cause autism. No research has shown a link between receiving vaccines, or any vaccine ingredient, and developing autism spectrum disorder (ASD).

Vaccines are safe and play a crucial role in protecting children from serious diseases. Vaccines undergo rigorous and stringent testing to ensure they meet the highest safety and efficacy standards.

This medical myth originates from a fraudulent 1998 study by Andrew Wakefield, an anti-vaccine activist, who falsely claimed a link between the measles, mumps, and rubella (MMR) vaccine and autism.

He suggested a link between the MMR vaccine and autism. However, he fabricated and falsified the results of the study, and had a financial conflict of interest on the topic. This caused a sharp decline in vaccination uptake, which lead to a number of global measles outbreaks and resulting deaths.

The journal publically withdrew his study and he lost his licence to work in the United Kingdom due to ethical and medical misconduct.

Children often receive an autism diagnosis around the same time they receive their routine vaccinations, which includes the MMR vaccine. However, decades of scientific research establishes that the MMR vaccine, or ingredients such as thimerosal, does not cause autism.

At present, researchers do not fully understand the potential causes of autism. However, evidence suggests that it may occur due to an interaction of genetic and environmental factors. While these factors may increase the likelihood of developing autism, they are not definitive causes.
