Vaccinations provide protection against a number of severe childhood communicable diseases, such as polio, measles, and pertussis. However, not all parents follow the recommended immunization schedules for their young children, a decision which could lead to increased disease incidence and prevalence. The purpose of this DNP project was to address the gap-in-practice related to ineffective strategies to reduce vaccination refusal among parents. This systematic review sought to understand strategies effective at teaching new mothers the importance of vaccinating their children. The theoretical foundation for addressing this question is Rogers’ protection motivation theory, which explains that sources of information, mediating cognitive processes, and modes of coping all contribute to an individual’s willingness or refusal to engage in protective behaviors. The evidence aimed at answering the practice-focused question was obtained through a search of Walden library databases. The PRISMA flow diagram and the Revised Standards for Quality Improvement Reporting Excellence tool were used to organize and evaluate relevant interventions. Three studies met the inclusion criteria. While none of these studies reported an increase in vaccination rates, the findings indicate that educational interventions, including videos, handouts, and tailored messages presented on the Internet are effective at promoting a more positive attitude towards vaccination. This project supports positive social change by helping to improve the health of the population and reduce current disparities in immunization rates.
