Dr. Le-Bucklin’s Answer:
The Autism Speaks organization best summarizes the answer to this question below:
Though the debate over the role that vaccines play in causing autism grows more heated every day, researchers have still not found a definitive link between the two. According to organizations such as the Centers for Disease Control and Prevention, the American Academy of Pediatrics and the World Health Organization, there’s just not enough evidence to support the contention that vaccines – specifically thimerosal-containing vaccines – cause children to develop autism.
One study published in the medical journal Lancet faulting the measles-mumps-rubella (MMR) shot has since been questioned by its own authors, and many others have also failed to pass scientific muster. Still, the accusations continue, largely from parents of children on the spectrum, and it’s easy to understand why: There are still no answers to this day about what’s causing a disorder that appears to steadily be expanding its reach.
Note: I was recently interviewed by Lani, the mother of triplets and co-founder of the Multiples and More Blog Network. This question was from our interview.
