Former HHS Deputy Secretary and Acting CDC Director - Departed HHS; nominated to lead National Science Foundation

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.

Deputy HHS Secretary and Acting CDC Director - Formally adopted ACIP’s hepatitis B recommendation into CDC schedule on Dec 16, 2025

In December 2025, the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP)—reconstituted by Health and Human Services Secretary Robert F. Kennedy Jr.—voted 8–3 to end the universal recommendation for hepatitis B vaccination within 24 hours of all US newborns’ birth. On December 16, 2025, Acting CDC Director Jim O’Neill formally adopted the recommendation, shifting to individual-based or shared clinical decision-making for infants of mothers testing negative for hepatitis B, with any first dose suggested no earlier than two months old; birth doses remain advised for infants of positive or unknown-status mothers.

Deputy HHS Secretary and Acting CDC Director - Ratified ACIP’s revised hepatitis B recommendations, formally shifting CDC policy from universal to individualized newborn vaccination

On December 5, 2025, the Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP)—recently overhauled under Health and Human Services Secretary Robert F. Kennedy Jr.—voted 8–3 to end the longstanding recommendation that every U.S. newborn receive a hepatitis B vaccine dose within 24 hours of birth. For babies whose mothers test negative for hepatitis B, the panel now advises individualized decision-making with parents and suggests delaying the first dose until at least two months of age, while retaining the birth dose for infants whose mothers are infected or whose status is unknown; acting CDC Director Jim O’Neill ratified this on December 16, 2025.

Deputy Secretary, U.S. Department of Health and Human Services - Leading federal response to Minnesota fraud allegations

On January 5, 2026, Governor Tim Walz became the highest-profile political casualty of Minnesota's welfare fraud crisis, announcing he would drop his bid for a third term. The stunning reversal came just two days before a contentious January 7 House Oversight Committee hearing where Republican state lawmakers testified that Walz and Attorney General Keith Ellison ignored rampant fraud and silenced whistleblowers. Within 24 hours of that hearing, the Trump administration dramatically escalated its response: on January 6, HHS froze $10 billion in child care and family assistance funding to five Democratic states—California, Colorado, Illinois, Minnesota, and New York—citing fraud concerns but providing no evidence of wrongdoing outside Minnesota. A coalition of the five states sued immediately, and on January 9, U.S. District Judge Arun Subramanian granted a temporary restraining order blocking the freeze for 14 days. Hours later, Agriculture Secretary Brooke Rollins announced USDA would suspend an additional $129 million in federal awards to Minnesota, prompting Ellison to vow 'I'll see you in court.'

Deputy Secretary of Health and Human Services; Acting Director, Centers for Disease Control and Prevention - Tasked with implementing vaccine schedule changes at CDC

In his second term, President Donald Trump has moved to fundamentally recast U.S. childhood vaccination policy, arguing that the country gives too many shots compared with its peers. On December 5, 2025, after a federal vaccine advisory panel voted 8–3 to end the longstanding recommendation that all newborns receive a hepatitis B shot at birth, Trump signed a presidential memorandum ordering the Health and Human Services secretary and the CDC director to review the entire childhood schedule and align it where possible with “best practices from peer, developed countries.”
