Over 2,400 people have contracted measles in the United States so far this year, topping the total number of cases for 2025 in just seven months. At the same time, vaccination rates have been declining, and there’s a lot of conversation about what’s driving vaccine hesitancy and how to combat misinformation.
Elisabeth Marnik has lived in both worlds: She wasn’t vaccinated as a kid because her parents were concerned that vaccines could do harm. In high school, she fell in love with science. She went to college, got vaccinated, and then earned a PhD in immunology. She joins Flora to talk about what people misunderstand vaccine hesitancy, and how she approaches science communication in today’s messy information ecosystem.
