This project was conducted to determine the educational needs of public health nurses regarding childhood and adolescent immunizations among foster care youth. The needs assessment survey was designed to aid in increasing awareness of childhood and adolescent immunizations in this vulnerable population. There is a growing health concern about low immunization rates among childhood and adolescent youth, given the rise in vaccine-preventable diseases. Increasing rates of vaccine-preventable diseases in foster care children indicate that this population is in need of educated immunization advocates to assist in protecting them from contracting such diseases. Health advocacy and health education involves certain lifestyle choices, environmental conditions, and promotion of development of appropriate literature to assist in educating this vulnerable population.
