Since the commencement of his second term in January 2025, President Donald Trump, in close coordination with Secretary of Health and Human Services (HHS) Robert F. Kennedy, Jr., has initiated a systematic, far-reaching reconfiguration of the American public health landscape. Moving beyond traditional regulatory adjustments, the administration has utilized executive orders, personnel shifts, and significant budgetary restructuring to pivot the Department of Health and Human Services toward a philosophy termed "Make America Healthy Again" (MAHA).
This report outlines the key policy actions that have redefined federal public health, from the removal of digital databases to the fundamental restructuring of vaccine advisory committees and the termination of thousands of federal health workers.
The MAHA Agenda: A New Direction for HHS
The core pillar of the administration’s public health policy is the "Make America Healthy Again" initiative, formalized in an executive order on February 13, 2025. The initiative, led by Secretary Kennedy, explicitly aims to "re-direct our national focus" toward the systemic reduction of chronic diseases in children. By targeting obesity, diabetes, and mental health disorders through a lens that prioritizes environmental factors—such as food additives, pesticides, and vaccine schedules—the administration has signaled a definitive break from the previous federal focus on infectious disease management and established public health consensus.
Personnel and Structural Overhaul
The administration’s strategy has been marked by a radical "reduction in force" (RIF) and internal reorganization. By mid-2025, the administration successfully eliminated over 20,000 HHS positions. This was facilitated by the Supreme Court’s July 2025 decision to overturn a lower court injunction, allowing the administration to proceed with mass layoffs that had previously been blocked as likely unlawful. These cuts have gutted specific offices, including the HHS Office of Infectious Diseases & HIV Policy and the Office of Minority Health, fundamentally altering the department’s capacity to execute legacy public health programs.
Chronology of Key Policy Actions
The speed and scope of the administration’s policy shifts have been unprecedented. Below is a curated timeline of the most significant interventions:
- January 20, 2025: Executive orders mandate the removal of federal websites and databases related to Diversity, Equity, and Inclusion (DEI), LGBTQ+ health, and specific reproductive health metrics. While the administration agreed to restore these in September 2025, the initial months saw a significant void in accessible public health data.
- February 7, 2025: The NIH attempts to implement a 15% cap on indirect cost rates for research grants. Following a nationwide preliminary injunction in March and a permanent injunction in April, the policy remains mired in legal appeals.
- February 14, 2025: An executive order bans federal funding for schools and universities requiring COVID-19 vaccinations. By mid-March, all higher education institutions with such mandates had dropped the requirement.
- February 28, 2025: The "Richardson Waiver," which mandated public comment periods for agency rules, is rescinded. This allows HHS to implement changes to Medicaid and NIH funding without public input, significantly reducing transparency.
- March 17, 2025: The Surgeon General’s advisory on gun violence is removed from the HHS website, and the White House Office of Gun Violence Prevention is shuttered.
- June 9, 2025: Secretary Kennedy announces the dismissal of all 17 sitting members of the Advisory Committee on Immunization Practices (ACIP), replacing them with individuals skeptical of established vaccine policies.
- August 5, 2025: HHS cancels 22 projects worth $500 million in mRNA vaccine research, arguing that the technology failed to prevent upper respiratory infections.
- September 19, 2025: The FDA initiates a new review of mifepristone, citing a disputed report on adverse events.
- October 10, 2025: Over 1,000 HHS employees are terminated during a government shutdown, with significant losses at the CDC in the divisions of injury prevention and health statistics.
- January 5, 2026: HHS releases a memo significantly reducing the routine childhood immunization schedule, moving several vaccines—including hepatitis B, influenza, and rotavirus—to "shared clinical decision-making."
- April 10, 2026: An updated ACIP charter is published, removing the requirement for three annual meetings and placing the committee under stricter control of the CDC Director.
- October 8, 2026: HHS launches a new clinic at the NIH dedicated to studying "vaccine injuries" and incentivizes physicians to report suspected adverse events to the VAERS database.
Supporting Data and Evidence Conflicts
The administration’s data-driven arguments—specifically regarding vaccine safety—have frequently clashed with established scientific literature.
The Autism and Acetaminophen Debate
In September 2025, the administration linked acetaminophen use during pregnancy to autism, a claim that prompted immediate pushback from the medical community. Despite the absence of robust evidence, the FDA was directed to include new safety labels on acetaminophen. Furthermore, in November 2025, the CDC website was altered to state that a link between vaccines and autism "cannot be ruled out," a direct reversal of the scientific consensus upheld by the American Academy of Pediatrics (AAP) and the American Medical Association (AMA).
Measles Mortality Statistics
A public dispute in 2026 regarding measles deaths in Pennsylvania highlighted a change in how HHS reports mortality. By choosing to rely on National Center for Health Statistics (NCHS) records rather than local health department reports, the administration has created a discrepancy between state-reported data and federal figures, complicating the public’s ability to track the current measles epidemic.
Official Responses and Legal Challenges
The administration’s policies have been met with a wave of litigation from state attorneys general and professional medical organizations.
- Funding Clawbacks: When the administration attempted to pull back $11.4 billion in supplemental COVID-19 funding, 23 states sued. While some funding was restored to those states, the majority of the clawbacks remain in effect for Republican-led states that did not join the litigation.
- Vaccine Schedule Litigation: The revised childhood vaccination schedule, which effectively de-prioritized routine immunizations, was stayed by a federal judge in March 2026. The administration has appealed, and the legal battle over the CDC’s authority to alter these schedules remains ongoing.
- Professional Pushback: Major organizations like the AAP and the American College of Obstetricians and Gynecologists (ACOG) have been systematically excluded from ACIP working groups. In response, these groups have increasingly issued their own evidence-based guidance, creating a dual-layered reality for clinicians: federal recommendations that emphasize individual decision-making versus professional guidelines that maintain traditional public health standards.
Implications for the Future of Public Health
The long-term implications of these changes are profound and multi-faceted.
Regulatory Strain
The FDA’s new policy to allow drug approvals based on one clinical trial rather than two, combined with the "National Priority Voucher" program, is intended to speed up drug delivery. However, critics argue this risks "regulatory capture" and may overwhelm an agency already struggling with significant staff cuts, potentially leading to lower safety thresholds for new therapies.
The Erosion of "Trusted Authority"
Perhaps the most significant consequence is the erosion of the CDC’s role as a trusted national authority. By dismissing the ACIP, withholding CDC research reports (such as the 2026 COVID-19 vaccine effectiveness study), and dismantling the infrastructure for infectious disease tracking, the administration has signaled a permanent shift toward a decentralized and highly politicized public health model.
Impact on Vulnerable Populations
The removal of funding for sex education (TPP and PREP grants) and the restrictions on LGBTQ+ health data suggest that the administration is prioritizing ideological alignment over the collection of comprehensive public health statistics. As the administration moves into the latter half of 2026, the cumulative effect of these actions is a healthcare system where local, state, and federal guidance may increasingly diverge, leaving both clinicians and the public to navigate a fragmented landscape of health information.
The "Make America Healthy Again" agenda continues to evolve, with the administration showing no sign of slowing its efforts to dismantle legacy frameworks in favor of its new, highly contested health paradigms. Whether this approach leads to a reduction in chronic disease or a crisis of public trust remains the central question for the remainder of the presidential term.
