Episode 12: Expecting Protection: Building Vaccine Confidence for Moms-to-Be

This episode was updated in March 2026 to include a brief note acknowledging why vaccine decisions feel uniquely weighted during pregnancy — and why that instinct, while completely understandable, doesn't mean that caution and vaccination are in conflict.

Are vaccines safe during pregnancy—and why are they recommended?

In this episode, Heather explains how maternal immunization works, why certain vaccines are given during pregnancy, and how they protect both mother and baby. She walks through what the immune system is doing during this time, how antibodies are passed to the fetus, and what research shows about safety.

She also addresses common concerns and misconceptions, and explains why vaccination during pregnancy is one of the most effective ways to protect newborns in their earliest, most vulnerable weeks of life.
