• Trump signs executive order redefining U.S. childhood vaccine recommendations and directing legal challenges to state vaccine mandates. — President Trump signed Executive Order 14420 establishing "Gold Standard Childhood Vaccine Recommendations" aligned with peer nations' practices, reducing the number of recommended vaccines and doses. The order directs the Attorney General to challenge state vaccine-mandate laws on constitutional grounds (parental authority, religious freedom, disability accommodations, equal protection) and instructs federal agencies to ensure contractors and grantees comply with religious and medical exemptions. It also establishes an HHS Task Force to develop single-dose vaccine alternatives and reassess vaccine safety and timing.
• Trump signs executive order restructuring childhood vaccination schedule — Donald Trump signed an executive order directing sweeping changes to the CDC childhood vaccination schedule, including breaking the MMR vaccine into three separate shots, reducing recommended vaccines from 18 to 11 diseases, and moving several vaccines to "shared clinical decision-making." The order bypasses the CDC—the federal agency tasked with vaccine recommendations—and attempts to reinstate changes halted by a federal judge in March for violating federal law. Trump and HHS Secretary Robert F. Kennedy Jr. repeatedly invoked an unproven autism-vaccine link during the signing.
• Trump issued executive order mandating split MMR vaccine and separate childhood immunizations — Trump signed an executive order requiring the combined MMR vaccine to be administered as three separate single-disease shots and mandating that childhood immunizations be given at separate medical visits, once domestically available. The order reflects a decades-long personal belief that vaccines cause autism, a claim contradicted by scientific evidence. Sen. Bill Cassidy, a physician who confirmed RFK Jr. as health secretary, publicly opposed the order, stating vaccines are safe, effective, and do not cause autism, and that splitting vaccines will increase hesitancy and make children less safe.
• Trump issues executive order realigning U.S. childhood vaccine recommendations with peer-developed-nation standards — President Trump signed an executive order on August 10, 2026, directing the Department of Health and Human Services to implement "Gold Standard Childhood Vaccine Recommendations" aligned with practices in peer developed countries. The order identifies three vaccine categories (universal, high-risk, and shared clinical decision-making), directs HHS to develop single-dose vaccine alternatives to combination products, and instructs the Attorney General to challenge state vaccine mandate laws on constitutional grounds. The order emphasizes parental choice and religious exemptions while maintaining vaccine availability.
• Trump signed Executive Order 14420 establishing "Gold Standard Childhood Vaccine Recommendations" and directing federal agencies to challenge state vaccine mandate laws. — President Trump signed Executive Order 14420 on August 10, 2026, declaring a new set of "Gold Standard Childhood Vaccine Recommendations" based on a HHS scientific assessment. The order categorizes vaccines into three tiers: those recommended for all children (measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type B, pneumococcal disease, HPV, varicella); those for high-risk groups; and those based on shared clinical decision-making. The order directs the Attorney General to challenge state vaccine mandate laws and directs federal agencies to ensure contractors comply with parental choice and religious exemption obligations. It also establishes an HHS Task Force on Safer Childhood Vaccines to develop single-dose vaccine options and reassess vaccine schedules.
• White House issued fact sheet on executive order revising childhood vaccine recommendations — The White House published a fact sheet on August 10, 2026, describing an executive order signed by President Trump that revises U.S. childhood vaccine recommendations. The order reduces recommended routine childhood vaccines from 18 diseases to 11, recommends separating the combined MMR vaccine into three single-disease shots, and advises spacing vaccines across separate medical visits. The order directs HHS to present plans for vaccine research and directs federal agencies to advance the new recommendations. States with school vaccine requirements are advised to consider updating their laws accordingly.
• Trump issues executive order on vaccines attempting to reinstate vaccine schedule changes — Donald Trump issued an executive order attempting to reinstate sweeping changes to the US vaccine schedule previously made by Robert F Kennedy Jr, the health secretary, which had been halted by a federal judge. The order cannot change CDC recommendations or federal law, but experts warn it creates confusion and undermines public trust in vaccines. The order invokes religious freedom, potentially pressuring states to reduce vaccination mandates for school attendance.
• Trump issues executive order on childhood vaccine schedule — On Monday, Trump issued an executive order directing states to revise their recommendations on childhood vaccinations. The order calls for separating the measles, mumps, and rubella (MMR) vaccine into three single-disease shots administered at separate appointments, despite such separate vaccinations not being available in the United States. Trump falsely claimed the vaccines could be "quite lethal" in combination, contradicting scientific evidence of the MMR vaccine's safety and effectiveness. Separating vaccines would require multiple doctor visits, reducing vaccination rates among poor families and leaving communities more vulnerable to disease.

• Trump appoints climate science denier Matthew Wielicki to lead US Global Change Research Program — The Trump administration appointed Matthew Wielicki, a former geochemist who publicly denies established climate science and lacks formal training in climate science, to lead the US Global Change Research Program and oversee the National Climate Assessment. Wielicki has criticized "climate alarmism" online and cast doubt on climate science conclusions. The appointment occurs as the Trump administration has gutted climate research programs, shuttered data-collection offices, and previously shut down the online portal providing access to five editions of the congressionally mandated National Climate Assessment published since 2000.

• White House issued presidential memorandum directing HHS and CDC to review childhood vaccine recommendations against peer developed countries' practices — The White House issued a presidential memorandum on December 5, 2025, directing the Secretary of Health and Human Services and the Director of the Centers for Disease Control and Prevention to review the United States' core childhood vaccine recommendations against practices in peer developed countries. The memorandum states that the U.S. recommended vaccinations for 18 diseases as of January 2025, compared to 10 in Denmark, 14 in Japan, and 15 in Germany. It directs HHS and CDC to study whether peer countries' practices are superior and, if so, to update the U.S. schedule accordingly while preserving vaccine access.
• White House issues fact sheet on presidential memorandum directing vaccine schedule review — The White House issued a fact sheet on December 5, 2025, describing a Presidential Memorandum signed by President Trump directing the Secretary of Health and Human Services and the CDC Director to review U.S. core childhood vaccine recommendations against practices in peer developed countries. The memorandum instructs officials to update the U.S. schedule if they determine foreign practices are superior, while preserving vaccine access. The fact sheet states the U.S. currently recommends 18 diseases for universal childhood vaccination, compared to 10–15 in peer nations.

• Federal advisory panel votes to recommend scrapping infant hepatitis B vaccine — Kirk Milhoan, chair of the federal Advisory Committee on Immunization Practices (ACIP), appointed by Health Secretary Robert F. Kennedy Jr., announced the committee would vote Thursday on reversing the decades-old recommendation that newborns receive hepatitis B vaccination within 24 hours of birth. The panel, composed largely of Kennedy appointees skeptical of vaccine science, is also investigating whether childhood immunization schedules contribute to allergies and autoimmune disorders, focusing on aluminum adjuvants despite NIH findings of acceptable risk-benefit ratios.
• CDC ACIP delays vote on restricting infant hepatitis B vaccination — The CDC's Advisory Committee on Immunization Practices (ACIP) held a contentious meeting on December 4, 2025, to consider restricting hepatitis B vaccination for infants. After heated debate, a motion to delay the vote until December 5 passed 6–3. The committee, reconstituted with Trump-appointed members including anti-vaccine advocates and chaired by Kirk Milhoan (who promoted ivermectin), debated restricting a vaccine that has eliminated 99% of childhood hepatitis B cases since 1990 and carries a documented safety record across 1.4 billion doses over three decades. No new evidence of harm was presented.
• RFK Jr's vaccine advisory panel convenes to consider delaying hepatitis B vaccination for newborns — Robert F Kennedy Jr, US health secretary and anti-vaccine activist, convened his reconstituted vaccine advisory committee on December 4, 2025, to consider reversing decades of federal policy recommending hepatitis B vaccination for all newborns. Kennedy had dismissed all 17 members of the CDC's Advisory Committee on Immunization Practices earlier in 2025 and replaced them with vaccine skeptics aligned with his agenda. The panel has already voted to change influenza vaccine formulations and measles/mumps/rubella/chickenpox vaccination protocols.
• RFK Jr dismisses all members of CDC vaccine advisory committee and replaces them with vaccine skeptics — Earlier in 2025, Robert F Kennedy Jr dismissed all 17 members of the CDC's Advisory Committee on Immunization Practices and replaced them with his own appointees, including several vaccine skeptics aligned with his anti-vaccine agenda. This week, the committee's chair Dr Martin Kulldorff departed for another HHS role and was replaced by Dr Kirk Milhoan, a cardiologist critical of Covid-19 vaccines. The reconstituted panel has already voted to change influenza vaccine formulations and measles/mumps/rubella/chickenpox vaccination protocols.
• ACIP votes on restricting infant hepatitis B vaccine recommendation — The Advisory Committee on Immunization Practices (ACIP), a federal panel that advises the CDC on vaccine policy, held a contentious meeting and prepared to vote on whether to change the longstanding recommendation that all newborns receive hepatitis B vaccination within 24 hours of birth. The vote was delayed twice. The panel, reconstituted by Health Secretary Robert F. Kennedy Jr. with vaccine skeptics and anti-vaccine advocates, heard no new evidence of vaccine harm but proceeded toward a vote that could alter decades of immunization guidance affecting 1.4 billion people vaccinated over 30+ years.
• CDC Advisory Committee votes to limit hepatitis B vaccine access to newborns — The CDC Advisory Committee on Immunization Practices voted on December 5, 2025, to restrict hepatitis B vaccination from a routine universal recommendation to a "shared clinical decision-making" model requiring parental consultation with doctors. Most newborns will no longer automatically receive the vaccine at birth; instead, vaccination will be deferred to two months of age or later and made optional rather than standard. The decision marks the first time the CDC has limited access to a decades-old routine vaccination.

• White House issues press release misrepresenting Tylenol-autism research — The White House released a press release linking to scientific studies to support Trump's claim that acetaminophen (Tylenol) use during pregnancy causes autism. Medical experts found the studies provided only "weak" and "inconclusive" evidence. The release duplicated citations to create a false appearance of multiple independent confirmations, misrepresented study findings (claiming biological mechanisms were established when authors stated mechanisms remain unknown), and omitted contradictory research, including a large Swedish study showing associations disappear under rigorous sibling-control analysis.

• Case update — D.V.D. v. U.S. Department of Homeland Security (D. Mass.) 1:25-cv-10676 — The Supreme Court stopped a lower court's order which has prevented the administration from removing immigrants to third countries without an opportunity to present their claims of potential torture first. The Supreme Court's order is now in place while the litigation proceeds. Justices Sotomayor, Kagan, and Jackson dissented.
• CDC presentation included nonexistent vaccine study — On June 24, a presentation scheduled for Thursday's meeting of the CDC Advisory Committee on Immunization Practices was found to have included a study that does not appear to exist after it was published on the agency's website. The presentation by Lyn Redwood, a former leader of an anti-vaccine group, claimed that the nonexistent study found that the vaccine preservative thimerosal can have "long-term consequences in the brain."
• ACIP agenda cites study that author says was not conducted or published — The ACIP panel's new agenda cited a study that the cited author stated he did not conduct or publish, according to Reuters reporting. This continues a pattern of Kennedy's health department producing references to garbled or nonexistent studies while Kennedy repeatedly touts "gold-standard" science.
