State health officials from California, Oregon, Hawaii, and Washington have responded to recent changes made by the Centers for Disease Control and Prevention (CDC) to its “Autism and Vaccines” webpage. The West Coast Health Alliance released a joint statement emphasizing that vaccines are not linked to autism.
The Alliance highlighted that extensive research involving millions of people across multiple countries over several decades has shown no connection between vaccines and autism. They expressed concern about inaccurate claims recently posted on the CDC website.
“Autism is a complex neurodevelopmental condition with multiple contributing genetic and environmental factors. Suggesting it stems from any single cause, such as vaccination, misleads families who deserve accurate guidance. It is not only a disservice to families seeking clarity about vaccines but also potentially harmful to autistic individuals and their families,” the Alliance stated.
They reiterated that vaccines undergo thorough testing and remain essential in preventing infectious diseases. The officials stressed that public health guidance on immunization should be based on credible scientific evidence to assist parents and caregivers facing conflicting or incorrect information.
The Alliance advised families to consult trusted healthcare providers and reputable medical organizations, including the American Academy of Pediatrics, for reliable information.
