# Kati's Tiny Messengers: Dr. Katalin Karikó and the Battle Against Covid-19 - Hardcover

by **Megan Hoyt** (Author), **Vivien Mildenberger** (Illustrator)

**From the author of the National Jewish Book Award Finalist _Bartali's Bicycle_ comes the story of Katalin Karikó, the Nobel Prize-winning scientist whose research of mRNA led to the world-altering development of the Covid-19 vaccine.** **Perfect for readers who love science, STEM, and books like _Dr. Fauci: How a Boy from Brooklyn Became America's Doctor or Hidden Figures: The True Story of Four Black Women and the Space Race._**

When she was young, Katalin Karikó decided she would study science--even though she had never even met a scientist! But she was determined to learn as much as she could about the human body, and once she made a decision, she stuck with it. Katalin had to learn English while attending university, but she worked hard until she became a doctor.

After facing many challenges, including lack of research funding and harsh immigration policies, Kati and her family uprooted from Hungary and moved to America, where she became a top researcher. She knew that, with work, she could teach one of the building blocks of life, messenger RNA, to fight off harmful viruses. There was just one problem--no one else believed her.

Then, the COVID-19 pandemic hit, and Kati and her work were thrust into the spotlight. But with her unshakable will, she was ready to face the challenge.

Includes a note from Dr. Karikó, a time line, and more information about mRNA.
