HHS, CDC Announce New ACIP Members

WASHINGTON—SEPTEMBER 15, 2025— The U.S. Department of Health and Human Services (HHS) and the Centers for Disease Control and Prevention (CDC) today announced the appointment of five new members to the CDC Advisory Committee on Immunization Practices (ACIP). These appointments reflect the commitment of Secretary Robert F. Kennedy, Jr. to transparency, evidence-based science, and diverse expertise in guiding the nation’s immunization policies. In June, Secretary Kennedy reconstituted ACIP to restore public trust in vaccines.

“ACIP safeguards the health of Americans by issuing objective, evidence-based vaccine recommendations,” Secretary Kennedy said. “Its new members bring diverse expertise that strengthens the committee and ensures it fulfills its mission with transparency, independence, and gold-standard science.”

The newly appointed members are:

• Hillary Blackburn, PharmD, M.B.A., Director of Medication Access and Affordability, AscensionRx, St. Louis, Missouri. Dr. Blackburn leads initiatives to optimize medication access for underserved populations and improve affordability in value-based care. She previously served as Chief Pharmacy Officer at the Dispensary of Hope, overseeing formulary and research strategy. She is also a leader in professional pharmacy organizations, host of the Talk to Your Pharmacist podcast, and author of How Pharmacists Lead.
• Kirk Milhoan, M.D., Ph.D., Medical Director, For Hearts and Souls Free Medical Clinic, Kihei, Hawaii. Dr. Milhoan is a pediatric cardiologist and former U.S. Air Force flight surgeon, with two combat tours in Iraq.

He holds a Ph.D. in the mechanisms of myocardial inflammation.
• Raymond Pollak, M.D., F.A.C.S., F.R.C.S. Dr. Pollak is a surgeon, transplant immunobiologist, and transplant specialist who has published more than 120 peer-reviewed works and served as principal investigator on NIH transplant biology grants and numerous drug trials. He previously served as Chief of Liver Transplantation and Director of Multiorgan Transplant Programs at the University of Illinois and has held leadership roles with the United Network for Organ Sharing and the American Society of Transplant Surgeons.

“The new ACIP members bring a wealth of real-world public health experience to the job of making immunization recommendations,” said Deputy Secretary of Health and Human Services and Acting Director of the CDC Jim O’Neill. “We are grateful for their service in helping restore the public confidence in vaccines that was lost during the Biden era.”

ACIP provides recommendations  to the CDC Director and HHS Secretary on the use of vaccines for the control of vaccine-preventable diseases in the civilian population of the United States.
