A federal judge completely blocked the US government from making some pretty sweeping changes to childhood immunizations, delivering a significant blow to Health Secretary Robert F Kennedy Jr’s agenda, as reported by the BBC. This ruling basically puts the brakes on Kennedy’s efforts to loosen vaccine regulations, which he’s been pushing since taking office a year ago.
Kennedy had aimed to slash the number of recommended childhood shots from 17 down to just 11. He also fired all the existing members of the Advisory Committee for Immunization Practices (ACIP), the advisory panel of outside experts that normally makes recommendations to the US Centers for Disease Control and Prevention. He then replaced them with his own picks, many of whom have openly expressed skeptical views about vaccines.
Judge Brian Murphy, from the US District Court for the District of Massachusetts, didn’t just stop the vaccine schedule changes; he also suspended Kennedy’s appointments to that advisory panel. This means a scheduled Wednesday meeting for ACIP is now postponed, according to the Department of Health and Human Services (HHS).
The American Academy of Pediatrics, along with other major medical groups, had sued the government, arguing that Kennedy’s changes violated federal law
Judge Murphy’s 45-page ruling highlights that ACIP had strayed from its usual scientific, legally codified decision-making process. “Unfortunately, the Government has disregarded those methods and thereby undermined the integrity of its actions,” Murphy wrote, noting that Kennedy hadn’t used the “rigorous screening” typically involved when choosing panel members. Murphy also pointed out that the Trump administration had completely bypassed Acip when making changes to the vaccine schedule, calling it a “technical, procedural failure.”
These changes had really thrown a wrench into things for parents and doctors, causing a lot of chaos and confusion. People were especially worried about how insurance companies would cover immunizations that have long been considered vital for public health.
Respected medical groups have even been issuing their own recommendations to counter these new policies, arguing that they aren’t based in science and could endanger children’s health. Some states are even teaming up to encourage healthcare providers to stick to the pre-Kennedy immunization schedule.
Naturally, the Trump administration isn’t taking this lying down and is expected to appeal the ruling. HHS spokesman Andrew Nixon released a statement saying the agency “looks forward to this judge’s decision being overturned just like his other attempts to keep the Trump administration from governing.”
On the flip side, medical groups like the American Medical Association, which is the largest professional organization for doctors in the US, lauded the decision. They called it “an important step toward protecting the health of Americans, particularly children.”
