Elisabeth Marnik, 37, Leads Vaccine Outreach After Growing Up Unvaccinated

Summary
Since February, Elisabeth Marnik has served as executive director of The Evidence Collective, using her own path from unvaccinated child to immunologist to argue that empathy works better than shaming in vaccine communication.
At 23, Marnik sought every missed childhood shot before graduate school, a break from an anti-science evangelical upbringing in Connecticut shaped by her mother’s fears about vaccine side effects and distrust of doctors.
Her outreach now spans 64,000 Instagram followers, a 4,500-subscriber Substack and collaborations with influencers, religious leaders and journalists aimed at breaking online echo chambers around public health.
Marnik says her 2019 childbirth and brief hesitation over her newborn’s hepatitis B shot helped her better understand parental fear, reinforcing her view that mandates may be necessary but rarely persuade on their own.
Her mother still rejects most vaccines, though Marnik calls small shifts—accepting measles vaccine benefits and masking around a newborn—evidence that long, patient conversations can move people incrementally.
