Which statement best describes the relationship between vaccines and Autism Spectrum Disorder?

• A. There is no connection between vaccines and Autism Spectrum Disorder
• B. Vaccines can cause Autism Spectrum Disorder
• C. Vaccines cure Autism Spectrum Disorder
• D. Autism Spectrum Disorder is prevented by vaccines

Answer: (A)

Vaccines do not cause Autism Spectrum Disorder. This is supported by decades of research, including large population studies and systematic reviews, which consistently find no association between vaccination and autism—even for vaccines like MMR. The fact that autism symptoms are typically noticed around the same age as many childhood vaccines does not imply causation; correlation here is coincidental. Autism is a neurodevelopmental condition with strong genetic contributions and other non-vaccine factors, while vaccines are designed to prevent infections. There is no evidence that vaccines cure or prevent autism, or that they have any causal role in its development.
