This book is a go-to guide for all families seeking trustworthy information about the science and safety of vaccines. Paul A. Offit and Charlotte A. Moser—scientists and parents with decades of experience—equip readers with the facts they need to navigate vaccine decisions for the whole family, from babies to elders. In straightforward prose, they offer accessible and authoritative answers to today’s most common vaccine-related questions.

Offit and Moser explain how vaccines work, how they are made, and how they are tested. Chapters examine vaccine safety, ingredients, the workings of the immune system, and practical considerations from the implications of different medical conditions to missed doses. The book covers vaccines that have been available for decades as well as newer vaccines for illnesses such as RSV, COVID-19, and mpox, including both traditional and mRNA vaccines. The second half of the book is a guide to individual vaccines organized by age groups, including the first and second year of life, ages three to six, older children and teenagers, and adults. A timely resource for all families, this book allays unfounded fears and provides a clear, easy-to-understand picture of vaccines and vaccination.

Vaccines and Your Family is a revised and updated edition of Vaccines and Your Child (2011) that expands coverage to include all ages and addresses recent scientific progress. It explores the new recommendations and new questions regarding vaccines that have arisen in the intervening years.
