Model A is a univariate model. Sociodemographic characteristics were adjusted in Model B. All covariates were adjusted in Model C, including region, age group, education, occupation, monthly household income per capita, gravidity, parity, history of chronic disease, history of influenza vaccination, knowledge of COVID-19, and the other three risk perceptions. Model D only adjusted the significant covariates including region, age group, education and knowledge of COVID-19, and the other three risk perceptions based the Pearson's χ²-test.
