COVID-19疫苗加強劑接種意願的預測因素：對公共衛生傳播的影響

Predictors for the Intention to Receive the Booster Dose of COVID-19 Vaccine: Implications for Public Health Communications

The purpose of this study was to investigate factors that predicted citizens’acceptance of public health messages recommending a booster dose in fighting against the mutated virus Omicron of the COVID-19. Data were provided by 531 adult citizens in a cross-sectional online survey between December 20, 2021 and January 15, 2022 in Taiwan. The results indicated that citizens’vaccination intention was predicted by their perceptions of the severity of COVID-19, the benefits and barriers to vaccination. Citizens’vaccination intention was also influenced by their trust in authorities handling the epidemic, media misinformation and interpersonal communication. In general, data also indicated that psychological factors predict the COVID-19 vaccination intention better than demographic, cultural and individual factors. Public health messages should be tailored to communicate these issues, especially for older age groups and those without chronic diseases. The findings provided evidence in support of health behaviors theories in the context of receiving booster doses of the COVID-19 vaccine in a country where the pandemic was under control.
