Chinese parents' intentions to vaccinate their children against SARS-CoV-2 infection and vaccine preferences.

This study aims to determine the intention of Chinese parents to vaccinate their children against SARS-CoV-2. Secondly, preferences for foreign- or domestically made COVID-19 vaccines were also explored. A nationwide, cross-sectional, self-administered online survey based on the Health Belief Model (HBM) and new vaccine concerns was used. Participants were eligible if they were residents of China with children aged 12 years old or younger. A total of 2,026 parents responded to the survey. Half reported a probable intent (50.7%) and 26.9% reported a definite intent. The results of the data analysis of partial least squares structural equation modeling (PLS-SEM) found that perceived cost barriers (B = -0.210, < .001) and new vaccine concerns (B = -0.201, < .001) had major effects in vaccination intent. Important constructs of vaccine concerns that predict vaccination intent were efficacy (B = 0.898, < .001), followed by safety (B = 0.861, < .001), side-effect (B = 0.806, < .001) and faulty/fake vaccine (B = 0.579, < .001). Perceived benefits (B = 1.81, < .001), self-efficacy (B = 0.159, < .001) and severity (B = 0.083, < .01) were also significant predictors in vaccination intent. Almost two-thirds (62.0%; 95%CI 59.8 to 64.1) reported a preference for domestically made and 19.1% (95%CI 17.2 to 20.7) preferred foreign-made COVID-19 vaccines. Multivariable logistic regression analysis revealed that higher incomes and concern of side-effects of the new COVID-19 vaccine were two of the most important influencing factors of preference for a foreign-made vaccine. This study sheds light on the importance of addressing concerns of new vaccines and the helpfulness of HBM in understanding parental decisions toward their children being vaccinated against SARS-CoV-2.
