Excerpt from "Promoting Childhood Immunizations" Immunization was perhaps the single most beneficial public health measure of the 20th century. ?Vaccine manufacturers
work in tandem with government, academic, and nongovernmental agencies to develop safe and effective vaccines that
decreases health costs and improve compliance. Despite overwhelming evidence of vaccine safety, suspicion and
misconception continue in small groups of hesitant or resistant parents, often leading to outbreaks of vaccine-preventable
infections on the front lines of vaccination, nurse practitioners can improve vaccination rates by developing a trusting
relationship with parents and being armed with information based on sound clinical evidence. Sthe study that follows was
supported by the Intramural Research Program of the National Institutes of Health, Clinical Center, Department of Radiology,
and National Cancer Institute.
