Acceptance and willingness to pay for COVID-19 vaccines available in Vietnam: an online study during the fourth epidemic wave

Abstract

COVID-19 vaccines available in Vietnam have different prices, efficacies, and side effects. We studied acceptance and willingness to pay (WTP) for COVID-19 vaccines in Vietnam, using a self-designed online questionnaire. Respondents were 2093 unvaccinated adults. Multiple regression analyses identified factors associated with vaccine acceptance and WTP. Acceptance of free vaccines was around 90% for the three available in Vietnam (Astra Zeneca, SPUTNIK V, and Pfizer-BioNTech). WTP for the same vaccines was about 70%. Vaccine acceptance was associated with being female and/or chronically ill or undergoing COVID-19-related job changes. WTP was associated variously with family economic status, occupational changes due to COVID-19, chronic disease, and perceived risk of infection. Most respondents were willing to be vaccinated and many were willing to pay for it, depending on personal and family circumstances. Vietnam should budget for free vaccines to support those unable to pay.
