Immunologist Liz Marnik, raised unvaccinated, now advocates for science and empathy in vaccine discussions

Immunologist Liz Marnik grew up in a household that rejected vaccines, and she herself went without any immunizations into adulthood.

At age 23 she visited a travel clinic and received all standard vaccines, a decision that marked a personal reversal of her childhood beliefs.

When she became a mother in 2019, a difficult birth and a near-miss with a hepatitis B shot for her newborn forced her to confront the practical importance of early vaccination.

The experience deepened her empathy for people who fear vaccines, and she now argues that shaming skeptics does little to improve acceptance.

Marnik uses her platform as a scientist to call for patience and respectful dialogue rather than condemnation in vaccine conversations.
