Episode 7, Part 1: The Diseases That Vaccines Prevent

We’ve spent a lot of time talking about the risks and controversies surrounding vaccines. But what about the diseases they’re designed to prevent?

In this episode of Deep Dives, Dr. Justin Smith takes a closer look at the infectious diseases that once shaped childhood and pediatric medicine—and how vaccination has dramatically changed how often we encounter them.

We’ll explore what these infections actually look like, why some are more dangerous than others, and why understanding the diseases themselves is an essential part of making informed vaccine decisions.

We’ll also discuss one of the great paradoxes of preventive medicine: the more successful vaccines become, the easier it is to forget why we needed them in the first place.

This isn’t about exaggerating the dangers of infectious diseases or dismissing questions about vaccines. It’s about understanding both sides of the risk-benefit equation.

Because the vaccine is visible. The disease it prevents often isn’t.

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 dismissing legitimate questions can damage relationships between physicians and families.

Most importantly, we’ll talk about what it takes to rebuild credibility—not through blind trust or false certainty, but through honesty, transparency, humility, and a willingness to have difficult conversations.

Because trust isn’t something medicine can demand. It’s something we have to earn.

Deep Dives: Fear, Facts, and Finding Common Ground.

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 some common assumptions don’t match the evidence, and why transparency—not pretending conflicts don’t exist—is essential to rebuilding trust.
