Nurse Florence®, What Are Memory B Cells? is a warm and easygoing picture book that follows three curious girls, Jean, Condi, and Sonia, as they join Nurse Florence in the cafeteria to learn what memory B cells are and why they matter. The story blends kid-friendly dialogue with simple explanations, showing where these cells come from, how they help the immune system remember past invaders, and how healthy habits keep the body strong. It feels like a gentle science lesson tucked inside a casual lunchtime chat.

The girls wander over to Nurse Florence with the kind of natural excitement you’d see in a real school cafeteria, and that relaxed tone carries through the whole story. The explanations build step by step, first what B cells look like, then that they’re made in bone marrow, then how they “remember” infections and transform into plasma cells when needed. The pacing is slow enough for kids to follow but fast enough that it never drags. It reminded me of a friendly teacher who always knows when to pause and when to move on.

I also appreciated how the book doesn’t shy away from big ideas. The parts about abnormal B cells leading to autoimmune issues or cancers are handled simply and calmly, making the information clear without being frightening. It’s refreshing to see a children’s book trust young readers with real science instead of watering everything down. The drawings help too, they give the concepts a visual anchor without overwhelming the pages.

My favorite section comes near the end, when the girls start brainstorming ways to keep the immune system healthy. They take turns suggesting things like eating fruits and veggies, exercising, sleeping well, washing hands, managing stress, avoiding smoking or vaping, and staying up-to-date on vaccines. It feels lively and almost playful, like a little health pep talk disguised as a conversation between friends. It also helps kids connect the science to their real lives, which gives the book a nice sense of purpose.

Nurse Florence®, What Are Memory B Cells? is a warm, engaging introduction to immune science. I’d recommend it to kids who enjoy learning how the body works, to parents who want clear and friendly explanations, and to teachers looking for accessible science material. It’s upbeat, informative, and surprisingly charming, a great pick for sparking curiosity.
