Brief overview

An unvaccinated, homeschooled child became an immunologist who changes minds with empathy, patience and story, not facts.

  1. Relationships opened the door, not data aloneLiz says friendships with people outside her church made her realize you can be a good person and believe differently, which let her question everything she had been taught.
  2. Changing a mind can take fourteen yearsShe counts 14 years of conversations with her mother before hearing a single positive word about a vaccine.
  3. Lead with empathy and curiosityInstead of citing safety data, she asks a worried parent what they have heard and why they are worried, because someone made to feel stupid will not engage.
