Vaccinations have been instrumental in decreasing and eliminating many diseases that were once considered a threat to the world’s population. Yet, over the decades’ many individuals, have become vaccine-hesitant. Vaccine hesitancy, in general, is the delay or refusal of getting a vaccine to protect against disease. According to the World Health Organization (WHO) is a global public health threat. A literature review was conducted to examine how health behavioral theories could be used to understand and address vaccine hesitancy in adults. This study found that most individuals make their vaccination decisions according to perceived risks of disease and the threat of those risks to their wellbeing, as well as overcoming any barriers or obstacles to their health decision. In order to address the gaps in vaccine hesitant adults, and their communities we must develop targeted interventions using the Health Belief Model (HBM), Protection Motivation Theory (PMT), and 3C’s Framework in combination to understand the thought process on how individuals make health decisions. In the hope of creating more knowledgeable and healthier communities within the United States, it is vital to put more effort on health behavioral models to increase vaccine uptake. Additional interventions will need to focus on overcoming the barriers that can exist within different communities due to race, gender, or socioeconomic status.
