From Hesitant to Hopeful: Why Some Parents Don’t Vaccinate—and How We Bridge the Gap

Ever paused at a vaccine insert, googled an ingredient, or felt torn between fear and science? Dr. Elisabeth Marnik (@sciencewhizliz) wasn’t vaccinated as a child. She grew up in an anti-vax household—but today, she’s a scientist, professor, and mom who vaccinates her own children and helps others feel informed, not fearful. 🧬 In this episode, we talk about what changed her mind—and how we move the conversation on vaccines away from shaming and toward shared values like protecting our kids. We cover: What it was like growing up unvaccinated and how becoming a mom changed her entire perspective How mistrust in larger systems (schools, government, healthcare) fuels vaccine resistance What people often get wrong about vaccine hesitancy—and why yelling never changes minds The difference between being anti-vax and vaccine-hesitant—and why reducing it to a binary doesn’t help anyone Her powerful quote: “The reason my mom didn’t vaccinate is the same reason I chose to vaccinate—because I want to protect my kids.” How science communicators can do a better job at discussing vaccines This conversation was inspired by one of her Substack pieces: 📖 Read it here To connect with Dr. Liz Marnik follow her on Instagram @sciencewhizliz, check out all her resources at https://open.substack.com/pub/fromthescienceclass and https://www.elisabethmarnikphd.com/.
