Episode 6: Too Many Vaccines Too Soon?

This episode was updated in March 2026 to include a brief note acknowledging why the childhood vaccine schedule looks alarming at first glance — and why that instinct, while completely human, doesn't reflect how the immune system actually works. 

Heather breaks down one of the most common concerns parents have about vaccines: the childhood schedule. Why are so many given so early? Is it too much for a baby’s immune system?

In this episode, she walks through how the immune system actually works, why modern vaccines are designed the way they are, and what decades of research show about safety. She also explains why delaying or spacing out vaccines can leave children vulnerable when they need protection the most.

If you’ve ever looked at the schedule and felt overwhelmed, this episode will help you understand what’s really going on beneath the surface.
