Conceptual Models and Coping Strategies of “Vaccine Hesitancy”: A Review Study

According to WHO (World Health Organization) estimates, vaccination can prevent 2.5 million deaths each year. The vaccination plan has played a significant role in reducing the mortality and morbidity of infectious diseases of great public health significance. The high vaccination rate not only provides direct protection for the vaccinated individuals, but also plays an indirect protective effect for the entire community. However, more and more people choose to postpone or refuse vaccination. People's hesitancy on vaccination has become an increasingly serious problem, leading to the resurgence of vaccine-preventable diseases. Vaccine hesitancy is affected by many factors. Countries need to carry out in-depth research to ensure vaccine coverage and minimize vaccine hesitancy, which has become an international priority. This article summarizes the research background of vaccine hesitancy, the definition of vaccine hesitancy, the influencing factors and conceptual models of vaccine hesitancy, and proposes coping strategies of vaccine hesitancy through a review of existing research and literature.
