In this episode of A Moment in Health, Dr. Ashish Jha explains how 99% of new hepatitis B infections can be prevented with a universal newborn vaccine and critiques the recent ACIP decision to step away from that recommendation. He reviews a new New England Journal of Medicine study showing that one dose of the HPV vaccine is non-inferior to the traditional two-dose schedule, reducing barriers to protection. Dr. Jha is joined by Cate Ryan, Brown Class of 2021 and current Harvard public health student, who reflects on how reporting on science during the pandemic shaped her path in public health and how issues like housing stability continue to drive her work today.

Dr. Jha discusses:

• Universal Hepatitis В Vaccination at Birth — CIDRAP
• Noninferiority of One HPV Vaccine Dose to Two Doses — New England Journal of Medicine

Cate Ryan is an MPH candidate at the Harvard T.H. Chan School of Public Health, focusing on the intersection of health and housing. She graduated from Brown in 2021 with a cell and molecular biology major and was the former senior science and research editor for the Brown Daily Herald, as well as the producer of the COVID Pod with Dr. Ashish Jha.

Dr. Ashish K. Jha is the dean of the Brown University School of Public Health.

In this episode of A Moment in Health, Dr. Ashish Jha highlights a striking new statistic: 40% of fully subsidized ACA enrollees had no insurance claims last year — a number far higher than the 15–20% typically seen in employer-based plans. He then reviews a major New England Journal of Medicine trial showing that a modified mRNA influenza vaccine reduced lab-confirmed flu infections by 35% compared to traditional flu shots, producing stronger immune responses with slightly more short-term reactogenicity. Associate Professor of the Practice Dr. Craig Spencer, emergency physician and public health leader, joins to discuss his experience attending the Children's Health Defense conference in Austin — unpacking the movement’s growing cohesion, the small but vocal anti-vaccine contingent, and why many attendees feel unheard by the health system.

Dr. Jha discusses:

• Efficacy, Immunogenicity, and Safety of Modified mRNA Influenza Vaccine — New England Journal of Medicine
• I’m a physician who went to the anti-vaccine movement’s biggest gathering. More of my colleagues should too — STAT

Dr. Craig Spencer is an emergency medicine physician and an Associate Professor of the Practice of Health Services, Policy and Practice at Brown University School of Public Health. As a physician he focuses on frontline preparedness, both in the U.S. and globally, especially on the impact of COVID-19 on health systems. This includes the real world impact of pandemic preparedness – or lack of preparedness – for clinicians and patients, particularly from a humanitarian perspective.

In this episode of A Moment in Health, Dr. Ashish Jha highlights a striking data point: 13.1% of U.S. adolescents and young adults report using AI tools for mental health advice, with 93% saying the guidance was helpful. He reviews a 2022 study from Italy’s Marche region showing that improving ventilation in more than 10,000 classrooms reduced SARS-CoV-2 transmission by nearly 80%, underscoring the enormous impact of better indoor air quality on respiratory infections. Georgia Lagoudas, Senior Fellow at the Pandemic Center, joins to explain why indoor air quality standards in the U.S. are outdated, the benefits improving indoor air quality can have and the progress we have made.

Dr. Jha discusses:

• Use of Generative AI for Mental Health Advice Among US Adolescents and Young Adults — JAMA Network Open
• Increasing ventilation reduces SARS-CoV-2 airborne transmission in schools: A retrospective cohort study in Italy's Marche region — Frontiers in Public Health
• The Effect of Air Purifiers in Schools — Resources for the Future

Dr. Georgia Lagoudas is a Senior Fellow at the Brown University School of Public Health’s Pandemic Center. She recently served as Senior Advisor for Biotechnology and Bioeconomy at the White House Office of Science and Technology Policy. During her time at the White House, she coordinated a variety of initiatives, including drafting and implementation of an Executive Order on Advancing the American Bioeconomy, as well as launching a White House Initiative to improve indoor air quality.
