Deep Dives is a podcast that takes a thoughtful, evidence-based look at the parenting and pediatric topics people argue about most—without the outrage, oversimplification, or false certainty.

Episode 6: Why Trust in Medicine Has Declined Trust in medicine wasn’t lost overnight, and we can’t rebuild it by simply telling people to “trust the science.” In this episode of Deep Dives, Dr. Justin Smith explores how historical medical mistakes, pharmaceutical scandals, and the COVID-19 pandemic contributed to growing skepticism toward doctors, scientists, and public health institutions. We’ll examine where medicine has fallen short, why communicating uncertainty matters, and how dismissi...

Episode 5-Big Pharma, Money and Conflicts of Interest
Can we trust vaccine recommendations when pharmaceutical companies make money from vaccines? It’s a fair question—and one that deserves more than simply being told to trust the system. In Episode 5 of Deep Dives, we follow the money: how vaccine economics actually work, where pharmaceutical incentives and conflicts of interest exist, and what safeguards are designed to separate financial interests from vaccine recommendations. We’ll also talk about where skepticism is justified, where s...

Episode 3-Too Many, Too Soon
Episode 3: Too Many, Too Soon? Are kids getting too many vaccines too early? In this episode of Deep Dives, we take that concern seriously and look at why the modern vaccine schedule can feel overwhelming, how much antigen exposure children actually receive, and what we know about the immune system’s ability to handle it. We’ll also dig into the evidence comparing children vaccinated on schedule with those who receive vaccines later, and talk about the often-overlooked tradeoffs of delaying. ...

Episode 2-Andrew Wakefield and the MMR Scare
In 1998, a small study by Andrew Wakefield sparked one of the most influential vaccine scares in modern history—but the story behind the MMR controversy goes far beyond a single scientific paper. In this episode of Deep Dives, we examine what Wakefield actually claimed, the financial conflicts and research misconduct that later came to light, why the paper was retracted, and how its impact continues to shape conversations about vaccines and autism nearly three decades later.

Episode 1: Why Did Vaccines Become So Divisive? Vaccines were once seen mostly as a medical tool, but over time they became tied to trust, politics, parenting, identity, and fear. In this episode, we look at how that happened—how changing public health messages, social media, personal stories, institutional distrust, and genuine uncertainty helped turn a medical question into one of the most emotionally charged debates in parenting. The goal isn’t to dismiss concerns or force agreement, but t...
