The Biden administration, through the Department of Health and Human Services (HHS), announced the appointment of two new physicians to the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) on Friday, February 28, 2026. The appointments of Dr. Sean G. Downing, and Dr. Angelina Farella reflect a commitment to bolstering the committee with frontline clinical experience and a renewed focus on transparency in guiding the nation’s immunization policies. This move comes after Secretary of Health and Human Services Robert F. Kennedy, Jr. reconstituted ACIP in June 2025 with the stated goal of restoring public trust in vaccines.
ACIP plays a critical role in public health, providing recommendations to the CDC Director and HHS Secretary regarding the employ of immunizations to control vaccine-preventable diseases across the United States. The committee’s guidance directly impacts vaccination schedules for children and adults, as well as recommendations for specific populations. The recent appointments signal an effort to ensure these recommendations are informed by a diverse range of clinical perspectives.
New Voices on the Advisory Committee
Dr. Sean G. Downing, a physician specializing in both Internal Medicine and Pediatrics, brings over two decades of experience in primary care to the committee. Currently practicing in Sarasota, Florida, Dr. Downing holds admitting privileges at Sarasota Memorial Hospital and provides concierge care for patients of all ages. His background also includes function with medically uninsured patients in Nashua, New Hampshire, and experience in emergency and urgent care settings. Dr. Downing completed his combined Internal Medicine and Pediatrics residency at Brown University, following his medical degree from Georgetown University School of Medicine, where he also received graduate training in physiology and pharmacology.
Dr. Angelina Farella, a pediatrician and owner of A Brighter Tomorrow Family Health and Wellness in Webster, Texas, has dedicated more than 20 years to pediatric care. Since establishing her own practice in 2004, she has also served in various clinical roles, including pediatric urgent care and locum tenens positions. Dr. Farella completed her pediatric residency training at the University of Texas Medical Branch (UTMB), serving as Pediatric Chief Resident, and held academic appointments as Clinical Assistant Professor at UTMB and Adjunct Clinical Professor at William Carey University College of Osteopathic Medicine. She earned her medical degree with honors from Ross University School of Medicine and a Bachelor of Arts in Biology from Rutgers University.
A Focus on Transparency and “Gold-Standard Science”
Secretary Kennedy emphasized the importance of rigorous scientific scrutiny and open deliberation within ACIP. “ACIP must scrutinize the evidence openly, inquire hard questions, and earn the nation’s confidence through transparent deliberation,” Secretary Kennedy said. “Dr. Downing and Dr. Farella bring decades of real-world experience caring for children, adults, and families—and that frontline perspective is essential to making recommendations that are grounded in gold-standard science and worthy of public trust.”
The emphasis on “gold-standard science” reflects a broader effort to address concerns about vaccine hesitancy and rebuild confidence in public health recommendations. The appointments are intended to bring a practical, patient-centered approach to the committee’s deliberations, ensuring that recommendations are not only scientifically sound but also relevant to the experiences of individuals and families.
CDC Leadership Supports the New Appointments
CDC Acting Director Jay Bhattacharya, MD, PhD, echoed Secretary Kennedy’s sentiments, stating that “Public health works best when the science is rigorous and the process is transparent.” He added that the new appointments would “strengthen ACIP with experienced clinicians who understand how immunization guidance matters for patients and families.”
The appointments come at a time when public health agencies are working to maintain high vaccination rates against a range of preventable diseases, including influenza, measles, and COVID-19. Maintaining public trust in vaccines is crucial for achieving herd immunity and protecting vulnerable populations.
The Advisory Committee on Immunization Practices is scheduled to meet again in June 2026 to discuss updates to the recommended immunization schedule for adolescents and adults. Further information about ACIP meetings and recommendations can be found on the CDC website.
