COVID-19 vaccine uptake and its determinants among teenagers and their parents in Zhejiang, China: An online cross-sectional study

Abstract

Objective: To examine COVID-19 vaccine uptake and its determinants among teenagers and their parents in Zhejiang, China. Methods: An online cross-sectional study was conducted among parents of teenagers in Zhejiang, China from May 1 to 31, 2022. Data were interpreted via univariate and multivariate analyses using the statistical package for the social sciences (SPSS) program. Results: A total of 11 115 (96.11%) participants and 11 449 (99.00%) of their children in Zhejiang, China had been vaccinated against COVID-19. Children whose parents did not receive COVID-19 vaccination were 19 times (aOR 18.96, 95%CI 12.36-29.08) more likely to be unvaccinated than their counterparts. In addition, children with no previous influenza vaccination, those whose parents doubted the COVID-19 vaccine’s safety or effectiveness, were 6.11 times (aOR 6.11, 95%CI 2.80-13.34), 8.27 times (aOR 8.27, 95%CI 5.33-12.83), and 2.69 times (aOR 2.69, 95%CI 1.11-6.50) more likely to be unvaccinated than their counterparts, respectively. COVID-19 vaccine uptake varied between different sociodemographic groups. However, the odds of receiving the COVID-19 vaccine decreased as age and education level increased. The main refusal reasons claimed by participants were that they had medical conditions that may not qualify them for vaccination (53.78%), followed by safety concerns about the vaccine (13.56%), not knowing where to get vaccinated (6.44%), and concerns about fertility issues (5.56%). Conclusions: Despite a highly encouraging level of COVID-19 vaccine uptake in Zhejiang, China, the elderly and highly educated people had lower COVID-19 vaccine uptake. It is suggested that tailored health education strategies should be taken to increase the COVID-19 vaccine uptake in such groups. Furthermore, with vaccination rates at such a high level, the pandemic is still ongoing, and public confidence in vaccines may decline. Thus, sufficient evidence-based information regarding COVID-19 vaccines should be provided to the public.
