From: COVID19 vaccine intentions in South Africa: health communication strategy to address vaccine hesitancy

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
