QUOTE : Ask the Aztecs and the Incas whether or not they would have liked to have access to vaccines. Oh, wait, you can't. They're dead. Vaccination is one of the best things that has happened to civilization. Empires toppled like sandcastles in the wake of diseases we do not give a second thought to today. If taking a moment to elaborate on that point will make this book unpopular with a large group of antivaxxers, that’s okay. This feels like a good hill to die on. It’s surely a better one than the Incas got.
