An mRNA vaccine had never been made before, and she faced frequent criticism and was told by other scientists she would never succeed. After many years of hard work and dedication, she figured out how to use mRNA to make a vaccine--and when a deadly virus called COVID-19 started infecting millions of people, Kati's invention turned out to be exactly what the world needed. Never Give Up is the inspiring true story of a determined scientist who proved that a little bit of curiosity and a lot of hard work can save lives." -- Amazon.com.
