The U.S. Centers for Disease Control and prevention (CDC) website is undergoing changes to reflect a discussion of potential links between vaccines and autism, following a directive from Health Secretary Robert F. Kennedy Jr. [[1]].

U.S. Health Secretary Robert F. Kennedy Jr. has directed the Centers for Disease Control and Prevention (CDC) to modify its website to include a discussion linking vaccines to autism cases, despite stating he does not believe vaccines cause autism.

U.S. Secretary of Health Robert F. Kennedy Jr. revealed on Friday, September 6, that he has instructed the Centers for Disease Control and Prevention (CDC) to modify its website to associate vaccines with cases of autism.
While Kennedy Jr. has clarified that he does not assert vaccines *cause* autism, he believes there is insufficient evidence to rule out a potential link. However, changes made to the agency’s website now present immunization and autism as closely related concepts. This move comes as vaccine confidence remains a critical public health concern.
The CDC, an agency now under the direction of an advisor to the Secretary of Health, updated its website on Wednesday, September 4, to emphasize that the claim vaccines “do not cause autism” is not based on scientific evidence.
The updated site also includes statements such as that scientific studies “have not ruled out the possibility that childhood vaccines cause autism” and that the CDC does not associate immunization with autism “to avoid vaccine hesitancy.”
Decision Follows a Pattern of Actions Discouraging Vaccination
The CDC added that the Department of Health and Human Services (HHS) is reviewing the causes of autism and investigating potential causal links with vaccines. This decision by Kennedy Jr. is the latest in a series of actions by the U.S. government that appear to discourage vaccination.
In August, the government led by Republican Donald Trump appointed Jim O’Neill, a senior official close to Kennedy Jr., as interim director of the government agency following the resignation of Susan Monarez, who claimed she was dismissed for opposing the Secretary of Health’s requests.
Furthermore, the effectiveness of some vaccines has been questioned by U.S. officials, including President Donald Trump, who in September raised doubts about the success of COVID-19 vaccines by demanding that pharmaceutical companies disclose their success rates.
The state of Florida, governed by Republican Ron DeSantis, announced in September plans to end mandatory vaccinations, a decision experts have lamented, as it could pave the way for the resurgence of diseases previously eradicated in the country.
