RFK Jr.'s vaccine panel threatens to change hepatitis B schedule

Trump administration updates CDC vaccine panel charter to allow RFK Jr. to handpick members after court blocked his hepatitis B vaccine changes.

Objective Facts

The US Department of Health and Human Services on April 9, 2026, adopted new rules allowing Health Secretary Robert F. Kennedy Jr. to handpick members of the CDC's vaccine advisory panel, serving as a workaround for a recent court ruling. U.S. District Judge Brian E. Murphy issued an injunction on March 16, 2026, finding that federal officials likely violated established legal procedures in both rewriting vaccine guidance and restructuring the advisory panel. The ACIP panel, handpicked by RFK Jr., had voted on December 5, 2025, to eliminate the recommendation that all infants be vaccinated against hepatitis B at birth. HHS spokesman Andrew Nixon downplayed the significance of the new charter changes, saying they are routine statutory requirements and do not signal any broader policy shift.

Left-Leaning Perspective

Paul A. Offit, director at the Children's Hospital of Philadelphia Vaccine Education Center, told Chemical & Engineering News he was relieved by the March ruling: "It's just—finally! Since February, when RFK Jr. was sworn in, you just held your breath at every ACIP meeting." Dr. Richard Besser, president of the Robert Wood Johnson Foundation, declared it "a triumph of science over misinformation" and "a huge blow to Kennedy's vaccine policies," while American Academy of Pediatrics president Dr. Andrew Racine said the ruling "re-established a degree of clarity" about childhood vaccinations. Attorney Richard Hughes IV, representing the plaintiffs, stated in the Pharmaceutical Executive report that "this ruling is a momentous step toward restoring science-based vaccine policymaking" and that "the judge recognized that the actions of Secretary Kennedy and the Advisory Committee on Immunization Practices are not grounded in science and that they are destructive." However, left-leaning outlets have now grown concerned that the April 2026 charter changes represent an attempt by Trump administration health officials to broaden committee membership and "evade the type of legal challenge that has left the currently appointed body in limbo." Critics in outlets like Business Story characterize the new charter as steering advisors toward issues favored by anti-vaccine campaigners, charging ACIP members with analyzing "cumulative effects of vaccines," which they argue mirrors efforts to blame vaccines for autism and neurodevelopmental disorders.

Right-Leaning Perspective

Lawyers with the U.S. Department of Justice, as reported by CNBC, argued that while HHS welcomed debate about vaccine policy, Kennedy and officials under him had broad authority to change it to address what they described as a decline in public trust in vaccines following the COVID-19 pandemic. Groups aligned with Kennedy's Make America Healthy Again movement like Children's Health Defense and the Independent Medical Alliance, reported by CNBC, characterized the March court decision as judicial overreach and argued that the changes advocated by the committee should not be controversial. According to NPR, HHS spokesman Andrew Nixon stated the administration plans to appeal, saying: "HHS looks forward to this judge's decision being overturned just like his other attempts to keep the Trump administration from governing." Regarding the April charter changes, NBC News reported that HHS spokesman Andrew Nixon downplayed the significance, saying the renewal "are routine statutory requirements and do not signal any broader policy shift," while attorney Aaron Siri, representing the Informed Consent Action Network, sent Kennedy a letter recommending changes to "clarify committee member criteria." The Boston Globe noted that Republican-led polling has found Kennedy's vaccine policies are widely unpopular even among supporters of his Make America Healthy Again movement.

Deep Dive

Kennedy fired all 17 existing ACIP members on June 9, 2025, citing need for a "clean sweep to reestablish public confidence," then initiated one of the most significant vaccine policy overhauls in decades, reducing recommended childhood diseases from 17 to 11 and ending hepatitis B birth dose recommendations. Judge Murphy's March 16, 2026 injunction focused on legal process rather than vaccine science itself, concluding that mass removal of committee members likely violated the Federal Advisory Committee Act and that policy changes lacked required expert balance and proper administrative procedures. The December 2025 ACIP vote to eliminate universal hepatitis B vaccination for newborns involved Kennedy allies including climate scientist Cynthia Nevison, businessperson Mark Blaxill from anti-vaccine groups, and sports medicine doctor Tracy Beth Høeg. What each side gets right: Pro-Kennedy advocates correctly identify that vaccine policy should be subject to evidence review and that some public trust declined post-COVID; they also legitimately question whether all recommended vaccines fit every population equally. Medical organizations and experts get right that the December ACIP proceedings lacked standard scientific rigor (no formal working group, non-expert presenters, slides withheld until meeting day) and that hepatitis B transmission in the U.S. remains possible through non-maternal routes. What they leave out: Kennedy's supporters largely avoid engaging with epidemiological data showing how targeted maternal testing failed historically to prevent childhood infections; left-leaning critics underplay legitimate public concerns about pandemic-era vaccine communication failures. Kennedy's April 2026 charter revisions represent an effort to circumvent the March court ruling by broadening committee membership criteria and revising operational documents to increase focus on potential vaccine harms, while HHS downplays these as routine procedural renewals. The unresolved question is whether the new charter language, particularly directing ACIP to analyze "cumulative effects of vaccines," will allow Kennedy to appoint similarly anti-vaccine members who can now claim broader qualifications, potentially resurrecting the December hepatitis B recommendation under new legal cover.

RFK Jr.'s vaccine panel threatens to change hepatitis B schedule

What's Going On

The US Department of Health and Human Services on April 9, 2026, adopted new rules allowing Health Secretary Robert F.

HHS spokesman Andrew Nixon downplayed the significance of the new charter changes, saying they are routine statutory requirements and do not signal any broader policy shift.

Left says: Vaccine experts hailed the March court decision as a "great day for children," but critics now warn that RFK Jr.'s new April charter changes attempt to resurrect his anti-vaccine agenda through revised administrative rules.
Right says: The Trump administration argues Kennedy has legitimate authority to reshape vaccine policy and defend the ACIP changes, with allied groups characterizing court interference as judicial overreach.
✓ Common Ground
More than 200 medical groups, including the American Medical Association, the March of Dimes, and the Autism Science Foundation, announced they would disregard the administration's changes and follow the AAP's immunization schedule instead—a position that transcends traditional partisan lines.
Republican Senator Bill Cassidy, a Louisiana physician whose support was critical to Kennedy securing Senate confirmation, broke ranks and wrote on social media: "As a liver doctor who has treated patients with hepatitis B for decades, this change to the vaccine schedule is a mistake."
Even Republican-led polling found that Kennedy's vaccine agenda is widely unpopular with voters, including supporters of his Make America Healthy Again movement, suggesting limited consensus even within conservative circles.

◈ Tone Comparison

Left-leaning coverage uses phrases like Offit saying he's "trying to be less giddy" and that he "just held your breath at every ACIP meeting because you didn't know what nonsense they were about to put out there," conveying relief and anxiety. Right-wing HHS spokesman Andrew Nixon uses combative language accusing the judge of attempting to "keep the Trump administration from governing," framing the ruling as political obstruction rather than legitimate judicial review.
