Abstract
Background: COVID-19 vaccine has been available in China since the beginning of the 2021, however, certain numbers of people are reluctant for some reasons to vaccinate. The high vaccine coverage is crucial for controlling disease transmission. Meanwhile, the vaccine hesitancy might be a barrier to the establishment of sufficient herd immunization. This study aims to investigate the prevalence of vaccine hesitancy towards the COVID-19 vaccine among different population groups, and explores the characteristics of different groups about vaccine hesitancy and common barriers and facilitators to vaccination decisions.Methods: The current survey was performed among students, public health professionals, medical workers and general population from January to March 2021 among Chinese from seven cities located in seven geographical territories of China. The questionnaire contained sociodemographic information, concerns about COVID-19 epidemic, general vaccination behavior and attitudes, the General Vaccine Hesitancy Scale, the COVID-19 Vaccine Hesitancy Scale and other potential factors of vaccine hesitancy. Univariate analysis was conducted by chi-squared test, and variables were significant at P < 0.10 were then included in a multivariable regression model.Results: The prevalence of COVID-19 vaccine hesitancy was 64.1% in our study, and a higher prevalence (73.7%) was in public health professionals compared to students (58.3%), medical workers (64.9%) and general population (61.1%). The results of multivariate analysis indicated that public health professionals were more likely to be hesitant against COVID-19 vaccine than general population (OR: 1.469, 95% CI: 1.069-2.019. And participants who needed transparent information about COVID-19 vaccine development, efficacy and safety (OR: 1.609, 95% CI: 1.343-1.928) and who have received negative information of COVID-19 vaccine (OR: 1.300, 95% CI: 1.130-1.496) were more likely to have vaccine hesitancy.Conclusions: Appropriate training in knowledge and communication skills about vaccines are necessary for public health professionals to help themselves and the public to increase their willingness of vaccination. Reducing the spread of misinformation and disseminating facts in a timely and accurate way will likely reduce vaccine hesitancy. Also, to establish suitable communication strategies between the government and the public and a warning system on infodemic would be helpful to improve public’s confidence in vaccination.
