ABSTRACT
Objective@#This study aims to investigate the willingness and influencing factors of COVID-19 vaccination among Chinese middle school students, and to provide a reference for promoting the implementation of COVID-19 vaccination among middle school students.@*Methods@#An online survey was conducted among middle school students in Beijing, Anqing of Anhui Province, Xi an of Shaanxi Province and Shenzhen of Guangdong Province, and 9 153 participants were enrolled in the present study. Single factor analysis and multinomial Logistic regression was used to determine the related factors of COVID-19 vaccination willingness.@*Results@#The prevalence of vaccine acceptance, vaccine hesitancy and vaccine refusal among middle school students were 60.05%, 31.59% and 8.36%, respectively. The results of Chi square analysis showed there were significant difference of COVID-19 vaccination willingness among sex, school residence, grade, region, vaccination willingness of surrounding classmates, vaccination willingness of others, fear of SARS-CoV-2 and risk of SARS-CoV-2 infection( χ 2=8.43-1 059.43, P <0.05). Multinomial Logistic regression analysis presented that, compared to "vaccine acceptance" group, those girls, non resident in school, living in Beijing or Anqing, disagree or uncertain with influenced by peers, disagree or uncertain with influenced by others, uncertain with fear of SARS-CoV-2, disagree or uncertain with having risk of SARS-CoV-2 infection were more likely to show vaccine hesitancy( OR =1.22,1.21,1.49,1.69,1.75,2.54,1.41,2.32,3.32,1.99,2.38, P <0.05). And those non boarding in school, living in Beijing or Xi an, disagree or uncertainty influenced by peers, disagree or uncertainty influenced by others, disagree with fear of SARS- CoV- 2, disagree or uncertainty in having risk of SARS-CoV-2 infection were more likely to show vaccine refusal ( OR =1.27, 2.29 ,1.46,3.88,2.37,2.31,1.47,2.14,4.24,1.47, P <0.05).@*Conclusion@#The willingness of COVID-19 vaccination among middle school students in four cities is low, and targeted interventions should be advocated to form herd immunity.
