The Trump Administration's Transformation of the NIH, CDC, and HHS Under Robert F. Kennedy Jr.

3 days ago: Bhattacharya Named Acting CDC Director

Overview

Jay Bhattacharya co-authored the Great Barrington Declaration in October 2020, publicly opposing the Centers for Disease Control and Prevention's pandemic response policies. Five years later, he now controls both the CDC and the National Institutes of Health—the two largest federal public health agencies—making him the most powerful health official in America outside the cabinet.

The appointment caps a turbulent year at the CDC. Since Robert F. Kennedy Jr. became Health and Human Services secretary in February 2025, the agency has lost its only Senate-confirmed director to firing, seen multiple senior officials resign in protest, shed nearly a quarter of its workforce, and overhauled the childhood vaccine schedule to recommend six fewer immunizations. The CDC now operates without permanent leadership while under the temporary control of someone who publicly challenged its core pandemic-era decisions.

Timeline

  1. Bhattacharya Named Acting CDC Director

    Leadership

    The NIH director was appointed to simultaneously lead the CDC, giving him control over both major federal health research and public health agencies.

  2. Acting CDC Director O'Neill Departs

    Leadership

    O'Neill left HHS with no public explanation. He was approaching the 210-day limit for acting officials under the Vacancies Reform Act.

  3. Childhood Vaccine Schedule Overhauled

    Policy

    Acting CDC Director O'Neill signed a memorandum reducing recommended childhood vaccines from 18 diseases to 11, modeled on Denmark's schedule.

  4. Fired CDC Director Testifies to Senate

    Investigation

    Monarez told senators Kennedy ordered her to pre-approve all vaccine panel recommendations regardless of evidence. Kennedy called her 'a liar.'

  5. CDC Director Fired After Less Than a Month

    Leadership

    Kennedy fired Monarez—the first Senate-confirmed CDC director ever dismissed. Multiple senior officials resigned in protest, citing politicization of public health.

  6. Monarez Confirmed as CDC Director

    Confirmation

    Career scientist Susan Monarez was Senate-confirmed as CDC director.

  7. O'Neill Sworn in as HHS Deputy Secretary

    Leadership

    Thiel associate Jim O'Neill was sworn in as HHS deputy secretary after 52-43 confirmation vote.

  8. Bhattacharya Takes NIH Leadership

    Leadership

    Bhattacharya became the 18th director of the National Institutes of Health.

  9. Bhattacharya Confirmed as NIH Director

    Confirmation

    The Senate confirmed Jay Bhattacharya as NIH director on a party-line 53-47 vote.

  10. Kennedy Confirmed as HHS Secretary

    Confirmation

    The Senate confirmed Robert F. Kennedy Jr. as Health and Human Services secretary by a 52-48 vote after contentious hearings focused on his vaccine skepticism.

  11. Trump Nominates Bhattacharya for NIH

    Nomination

    President-elect Donald Trump nominated the Great Barrington Declaration co-author to lead the National Institutes of Health.

  12. Great Barrington Declaration Published

    Policy

    Bhattacharya and two other scientists published the declaration opposing lockdowns, advocating 'focused protection' while allowing natural immunity to develop. Major health organizations and NIH leadership denounced it.

Scenarios

1

Bhattacharya Nominated as Permanent CDC Director

Discussed by: Health policy analysts at STAT News and Axios

The administration could nominate Bhattacharya for permanent CDC director, allowing him to retain both roles long-term. This would consolidate research and public health policy under unified leadership aligned with Kennedy's priorities. Senate confirmation would be contentious given Bhattacharya's pandemic-era positions, but Republicans hold a majority. The Vacancies Reform Act requires Trump to nominate someone within 210 days of Monarez's firing—a deadline approaching in late March.

2

New Permanent CDC Director Nominated From Outside

Discussed by: PBS News, federal health policy observers

Trump nominates a different candidate for permanent CDC director, ending Bhattacharya's dual role. This would address concerns about one person managing two major agencies in different cities. Finding a candidate who aligns with Kennedy's priorities, has sufficient credentials, and can win Senate confirmation may prove difficult—the first Senate-confirmed director lasted less than a month before being fired.

3

Extended Vacancy Continues Through Midterms

Discussed by: Federal News Network, political analysts

No permanent CDC director is confirmed before the 2026 midterm elections. The administration cycles through acting directors to comply with Vacancies Act limits while avoiding a potentially contentious confirmation battle. This would leave the CDC without stable leadership during a critical period, hampering long-term planning and institutional continuity.

4

Major Public Health Emergency Tests Leadership Structure

Discussed by: Former CDC officials quoted in CNN, STAT News

A significant disease outbreak or public health crisis forces rapid coordination between the NIH and CDC. The dual-director arrangement either proves efficient—with unified decision-making—or reveals strain, as one person cannot adequately lead two major agencies in different cities during an emergency. Former officials have warned that both agencies require full-time attention to respond effectively to threats.

Historical Context

Scott Pruitt Leads EPA After Suing It (2017-2018)

February 2017 - July 2018

What Happened

President Trump appointed Oklahoma Attorney General Scott Pruitt to lead the Environmental Protection Agency. Pruitt had filed or joined 14 lawsuits against the EPA and described himself as 'a leading advocate against the EPA's activist agenda.' He was confirmed 52-46 along party lines.

Outcome

Short Term

Pruitt pursued aggressive deregulation, rolling back Obama-era environmental rules. He faced mounting ethics scandals over lavish spending and management decisions.

Long Term

Pruitt resigned in July 2018 amid investigations. His tenure demonstrated that agency critics can pursue significant policy reversals from within, but also face institutional and political friction.

Why It's Relevant Today

Bhattacharya's appointment follows a similar pattern: a vocal critic of the agency's major policy decisions now controls it. Unlike Pruitt, Bhattacharya also retains leadership of a related agency (NIH), expanding his policy influence across federal health research and public health.

Francis Collins Denounces Great Barrington Declaration (2020)

October 2020

What Happened

Four days after Bhattacharya and colleagues published the Great Barrington Declaration, then-NIH Director Francis Collins emailed Anthony Fauci describing the authors as 'fringe epidemiologists' and calling for 'a quick and devastating published takedown.' The World Health Organization, American Public Health Association, and UK government also criticized the declaration.

Outcome

Short Term

The declaration was widely rejected by mainstream public health officials. Its authors faced professional criticism and accusations of promoting dangerous policy.

Long Term

The declaration gained political support from the Trump administration and conservative media. Post-pandemic reassessments of lockdown policies generated renewed interest in its arguments.

Why It's Relevant Today

The same NIH that orchestrated opposition to Bhattacharya's declaration is now led by Bhattacharya himself. He also controls the CDC, the primary agency that implemented the policies he criticized.

FEMA Director Under Multiple Administrations (Various)

Ongoing precedent

What Happened

Federal agency heads occasionally serve in multiple roles during transitions or emergencies. Acting officials have led agencies for extended periods when permanent nominees face confirmation delays or political obstacles.

Outcome

Short Term

Extended vacancies and dual roles typically function for routine operations but can strain capacity during crises.

Long Term

The Vacancies Reform Act of 1998 formalized time limits on acting officials specifically to prevent indefinite vacancies and ensure Senate confirmation.

Why It's Relevant Today

Bhattacharya's dual role is unusual in scope—leading the nation's primary biomedical research funder and its primary public health agency simultaneously, with headquarters 600 miles apart.
