While writing my book, I came to the realization that I have been part of what might be described as a sleeping giant—an organization known as the American College of Emergency Physicians (ACEP). In drawing this analogy, I believe it is fair to say a significant percentage of parents with sick infants seek immediate medical care at sites other than their primary care locations. Many of these infants and children will have received a recent immunization. Unless doctors working in emergency and urgent care fully understand and appreciate the objectives of the National Childhood Vaccine Injury Act (NCVIA) and the requirements of the Vaccine Adverse Event Reporting System (VAERS), the majority of adverse events will go unreported.
