❓WHAT HAPPENED: The Centers for Disease Control and Prevention (CDC) has revised its stance on vaccines and autism, stating that a link cannot be ruled out, a reversal from its previous position.
👤WHO WAS INVOLVED: CDC officials, Health Secretary Robert F. Kennedy Jr., Dr. Susan J. Kressly, Dr. Paul Offitt, and public health experts.
📍WHEN & WHERE: The changes were recently made on the CDC’s website.
💬KEY QUOTE: The updated wording indicates that a link between childhood vaccines and autism “cannot be ruled out.”
🎯IMPACT: The change shows Health and Human Services (HHS) Secretary Robert F. Kennedy is continuing to challenge establishment dogma in public health.
The Centers for Disease Control and Prevention (CDC) has revised language on its website addressing vaccine safety, drawing national attention and igniting debate inside and outside the agency. The updated wording indicates that a link between childhood vaccines and autism “cannot be ruled out,” a departure from the CDC’s long-standing position that no connection exists.
Health Secretary Robert F. Kennedy Jr., who has for years voiced concerns about certain vaccines, welcomed the CDC’s wording change. In September, he had noted that “Some 40-70 percent of mothers who have children with autism believe that their child was injured by a vaccine,” adding: “President Trump believes that we should be listening to these mothers instead of gaslighting and marginalizing them like prior administrations.”
The controversy comes as the CDC is initiating a new large-scale investigation into potential associations between vaccines and autism using the agency’s Vaccine Safety Datalink. At a September event focused on autism, President Donald J. Trump called for separating the combined measles, mumps, and rubella (MMR) vaccine into three individual shots, saying, “When you mix them, there could be a problem.”
The America First leader also criticized the current infant immunization schedule, characterizing it as too intensive. “For a little baby to be injected with that much fluid… it’s crazy,” he said.
