Role of literacy, fear and hesitancy on acceptance of COVID-19 vaccine among village health volunteers in Thailand

BACKGROUND: The roles of literacy, fear and hesitancy were investigated for acceptance of COVID-19 vaccine (AV) types among village health volunteers (VHVs) in Thailand. MATERIALS AND METHODS: A cross-sectional study was conducted using an unidentified online questionnaire to assess literacy, fear and hesitancy of COVID-19 vaccine acceptance among Thai VHVs between 1 and 15 October 2021. The questionnaire was developed based on the HLVa-IT (Health Literacy Vaccinale degli adulti in Italiano) for vaccine literacy (VL), using an adult Vaccine Hesitancy Scale (aVHS) for COVID-19 vaccine hesitancy (VH) and Fear of COVID-19 scale (FCoV-19S) for the distress of COVID-19 vaccine. The effects of VL, VH and vaccine fear (VF) on AV were estimated using multivariable logistic regression. RESULTS: A total of 5,312 VHVs completed the questionnaire. After adjustment with variables in the multivariable analysis, the VL score was insignificantly associated with increased vaccination (aOR = 1.002; (95%CI: 0.994–1.01)), while VF and VH significantly decreased the chance of vaccination, aOR = 0.966 (95%CI: 0.953–0.978) and aOR = 0.969; (95%CI: 0.960–0.979), respectively and VF and VH were negatively associated with AV for all types of vaccine preference, with VL showing a reverse relationship only for mRNA-based vaccines. CONCLUSION: VL may not increase AV among VHVs. To increase attitudes toward receiving COVID-19 vaccination in Thailand, the government and health-related organizations should instigate policies to significantly reduce VF and VH among Thai VHVs.
