Northeast health leaders say CDC's shift on vaccines, autism was "inconsistent with decades of research" and may lead to "unnecessary fear and harm."

A Harvard study found that the children of women who contracted COVID-19 while pregnant may be at an increased risk for autism and other diagnoses, raising new concerns about the CDC’s decision to stop recommending the vaccine to pregnant women.

Dr. Ralph Lee Abraham, the Louisiana surgeon general who halted his state’s vaccine promotion campaigns and delayed warning the public about a deadly whooping cough outbreak, has quietly been installed as the second-highest official at the Centers for Disease Control and Prevention.

Abraham ordered the Louisiana health department to stop promoting mass vaccinations during an uptick in influenza cases last winter.

Changing its web page, the CDC now promotes the myth that vaccines are linked to autism despite years of research refuting the claim.

Hundreds of scientific studies have found no link between vaccines and autism. But some doctors say they're fielding more and more questions from parents on the topic.

A major shift in federal health messaging has sparked intense concern among medical experts and autism advocacy groups. The sudden change, driven by political pressure, has raised questions about the reliability of public health communication and its impact on parents already navigating fear and confusion.
