This website was created by Julia Bradley for BMS 223-01: Public Health Concepts, at Grand Valley State University. The website is a submission for a course assignment. All information was obtained through the course textbook, Disease: Identification, Prevention, and Control by Barbara Hamann, the Centers for Disease Control and Prevention, the World Health Organization, www.vaccines.gov, the National Meningitis Association, and a number of university resources on regional vaccination requirements.
