Aug 11 (Reuters) - An influential U.S. medical journal is rejecting a call from Health Secretary Robert F. Kennedy Jr. to retract a large Danish study that found that aluminum ingredients in vaccines do not increase health risks for children, the journal's editor told Reuters. Kennedy has long promoted doubts about vaccines' safety and efficacy, and as health secretary has upended the federal government's process for recommending immunization.

A recent media report said he has been considering whether to initiate a review of shots that contain aluminum, which he says are linked to autoimmune diseases and allergies. The study, which was funded by the Danish government and published in July in the Annals of Internal Medicine, analyzed nationwide registry data for more than 1.2 million children over more than two decades. It did not find evidence that exposure to aluminum in vaccines had caused an increased risk for autoimmune, atopic or allergic, or neurodevelopmental disorders.

The work is by far the best available evidence on the question of the safety of aluminum in vaccines, said Adam Finn, a childhood vaccination expert in the UK and pediatrician at the University of Bristol, who was not involved in the study. "It's solid, (a) massive dataset and high-quality data," he said.

Kennedy described the research as "a deceitful propaganda stunt by the pharmaceutical industry," and said the scientists who authored it had "meticulously designed it not to find harm" in a detailed Aug. 1 opinion piece on TrialSite News, an independent website focused on clinical research. He called on the journal to "immediately retract" the study. "I see no reason for retraction," Dr. Christine Laine, editor in chief of the Annals and a professor of medicine at Thomas Jefferson University, said in an interview.
