CDC

My corkboard has identified a new suspect in the vaccine misinformation loop: the CDC communications department, apparently operating a fog machine with a government email address. The agency’s revised autism page reopens uncertainty around vaccines, while its separate MMR safety page says many carefully performed studies found no link between MMR vaccination and autism. That is not clarity. That is two official webpages standing in the hallway, pointing at each other, while parents are told to bring their own flashlight.

The contradiction matters because public-health guidance is supposed to reduce confusion, not make ordinary people perform a graduate seminar between school pickup and dinner. The autism page says the claim that vaccines do not cause autism is not evidence-based, according to the CDC’s current language, while also retaining a citation to a hepatitis B study reported by NOTUS as retracted and methodologically problematic. A retracted study should not be treated like a fresh clue in a detective novel unless the detective is selling supplements on a livestream.

Meanwhile, the CDC’s MMR page presents the more familiar evidence-based position: many carefully performed studies found no link between MMR vaccination and autism. Those pages do not create a productive scientific debate for families. They create a credibility crisis for the institution that is supposed to explain what is known, what is uncertain, and what has been discredited. The algorithm, naturally, sees only engagement potential. Every official wobble becomes premium content for rumor accounts, influencers, and anyone whose business model requires the public to stay permanently alarmed.

Associated Press coverage reported political responses and Senate scrutiny surrounding the CDC’s revised language. That response is part of the larger problem: scientific communication starts looking like political collateral, edited according to whichever faction is currently demanding a dramatic question mark. The beneficiaries are not the families stuck sorting claims from evidence. They are the panic merchants, who get to convert institutional ambiguity into clicks, subscriptions, and another exhausting group-chat emergency.

The CDC did not merely fail to clear the smoke. It appears to be revising the fog machine’s instruction manual while insisting everyone remain calm. People deserve public-health agencies that can acknowledge uncertainty without laundering discredited material or contradicting their own guidance. Follow the thread, sure—but check the knot before somebody charges admission to the maze.
