Introduction

      Vaccines are a hot topic today, but that’s really not anything new. They have been lauded, criticized, and discussed for hundreds of years, although the creation of new vaccines has certainly accelerated over the past 70 or so years. Yet dozens of misconceptions about vaccines still exist. For every person who embraces being fully vaccinated, there’s someone who questions certain vaccines or, worse, rejects them altogether, despite their proven benefits.

      This book is for both groups — the people who vaccinate themselves and their families but who want to know more about them, and the people who have questions about vaccines. Our goal is to have everyone vaccinated and, even more important, happy knowing they’re doing the best thing for their health.

About This Book

      Obviously, vaccines are the main topic of this book. But we intend to do more than just give you a vaccine schedule. We explain the history of vaccines (and it goes back much further than you might think), talk about the types of germs and diseases that led to vaccine development, and explain why the vaccine schedules are set up the way they are. We also discuss the myths about vaccines, especially with regard to children, and explain why the vaccine schedules have changed over the years.

      A quick note: Sidebars (shaded boxes of text) dig into the details of a given topic, but they aren’t crucial to understanding it. Feel free to read them or skip them. You can pass over the text accompanied by the Technical Stuff icon, too. The text marked with this icon gives some interesting but nonessential information about vaccines.

      One last thing: Within this book, you may note that some web addresses break across two lines of text. If you’re reading this book in print and want to visit one of these web pages, simply key in the web address exactly as it’s noted in the text, pretending as though the line break doesn’t exist. If you’re reading this as an e-book, you’ve got it easy — just click the web address to be taken directly to the web page.
