Table 1 Variable definitions
Variable | Instrument question | Response |
|---|---|---|
Vaccine intention | ‘To what extent do you agree or disagree with the statement: If a vaccine for COVID-19 were available, I would get it?’ | strongly agree/ somewhat agree/ somewhat disagree/strongly disagree |
Risk of infection | ‘Do you think you are likely to get the coronavirus?’ | Yes/No |
Efficacy | ‘Can you avoid getting Coronavirus?’, ‘Vaccine ineffectiveness is not the main reason why you would not take a vaccine for COVID-19’. To create a vaccine-specific efficacy variable, the two questions are interacted. If the respondent does not state vaccines to be ineffective, it takes the value one and believes that coronavirus can be avoided. | Yes/No |
