At first blush, this book seems a little alarmist. However, if you have any inkling of the influence of megacorporations, you'll realize that all of this is more than plausible. You need to read many books and talk to many people before you make vaccination decisions. You also have to look at everything you are doing to keep your baby healthy. For instance, if you are bottle feeding a baby who spends 10 hours a day in a crowded day care center, your approach must be different than for a breastfed baby who gets to stay at home.
