In this episode of the Contagion Podcast, we take on one of the most pressing challenges in modern medicine: vaccine hesitancy. As misinformation spreads rapidly across social media and trust in institutions continues to shift, clinicians are increasingly navigating complex, emotionally charged conversations with patients and families.

To explore this issue, we sit down with Dr. Lisa Hayes, a board-certified pediatrician, to better understand what vaccine hesitancy looks like today—from inside the exam room. From routine well-child visits to high-stakes discussions about safety and risk, Dr. Hayes shares her firsthand experience engaging with parents who are uncertain, skeptical, or simply overwhelmed by the volume of information coming at them from every direction.

We begin by examining how we got here. Vaccine hesitancy is not new, but it has evolved dramatically over time. From early debates around smallpox vaccination to the lasting impact of the now-debunked MMR-autism claims, historical events have shaped public perception in lasting ways. Layer onto that the rise of digital media, where health information—and misinformation—spreads faster than ever, and the COVID-19 pandemic, which further strained trust and amplified division.  

But this episode goes beyond history. We focus on the real-world dynamics of these conversations today. What are parents most concerned about? How do clinicians decide when to lead with data, when to lead with empathy, and how to balance both? And what happens when deeply held beliefs collide with public health recommendations?

We also take an honest look at the broader context of mistrust in healthcare, particularly among communities that have experienced bias, dismissal, or inequity. Understanding this backdrop is essential to rebuilding meaningful connections with patients.

Finally, we turn toward solutions. What strategies actually work? How can clinicians meet families where they are without compromising scientific integrity? And what does the future of vaccine communication look like in an era defined by information overload?

This is a conversation about more than vaccines—it’s about trust, communication, and the evolving role of the clinician in a rapidly changing world.
