Understanding the Prevalence and Associated Factors of Behavioral Intention of COVID-۱۹ Vaccination Under Specific Scenarios Combining Effectiveness, Safety, and Cost in the Hong Kong Chinese General Population

BackgroundThe prevalence of coronavirus disease ۲۰۱۹ (COVID-۱۹) vaccination is very critical in controlling COVID-۱۹. This study mainly aimed to (۱) investigate behavioral intentions of COVID-۱۹ vaccination under various specific scenarios, and (۲) associated factors of the afore-mentioned vaccination intentions. MethodsA random anonymous telephone survey interviewed ۴۵۰ Chinese adults from September ۱۶-۳۰, ۲۰۲۰ in Hong Kong, China. Nine scenarios of behavioral intentions of COVID-۱۹ vaccinations were measured combining effectiveness (۸۰% versus ۵۰%), safety (rare versus common mild side effect), and cost (free versus HK ۵۰۰). ResultsThe prevalence of behavioral intentions of COVID-۱۹ vaccination under the ۹ specific scenarios was very low and varied greatly (۴.۲% to ۳۸.۰%). The prospective countries of manufacture also influenced vaccination intention (eg, Japan: ۵۵.۸% vs China: ۳۱.۱%). Only ۱۳.۱% intended to take up COVID-۱۹ vaccination at the soonest upon its availability. The attributes of effectiveness and side effect influenced vaccination intention most. Positively associated factors of behavioral intentions of COVID-۱۹ vaccination included trust/satisfaction toward the government, exposure to positive social media information about COVID-۱۹ vaccines, descriptive norms, perceived impact on the pandemic, perceived duration of protectiveness, and life satisfaction. ConclusionIntention of COVID-۱۹ vaccination was low in the Hong Kong general population, especially among younger people, females, and single people. Health promotion is warranted to enhance the intention. The significant factors identified in this study may be considered when designing such health promotion. Future research is required to confirm the findings in other countries. Such studies should pay attention to the specific context of cost, safety, and effectiveness, which would lead to different responses in the level of behavioral intention of COVID-۱۹ vaccination (BICV).
