This handbook is intended to provide school authorities with a guide to the development of an effective school immunization program. The handbook is divided into three sections and seven appendices. Section One explains the legal definitions of various terms related to mandatory immunization practices. Section Two outlines the elements necessary for an efficient vaccine project, and Section Three provides sample procedures and activities as well as a range of frequently asked questions and answers relating to such a program. The appendices include the "Immunization Guidelines" of the New York State Department of Health and detailed excerpts from public health and education law texts dealing with the issue of compulsory immunization. A sample of the request form for exemption for religious reasons is also included. (LH)
