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
