SECONDARY outcome
Timeframe: 6 monthsPopulation: We corrected the sample size for the secondary outcome of intention
Intention to vaccinate was assessed with a single item, 'How are you currently feeling about getting the updated COVID-19 vaccine? Would you…' with the following response options: 1. Definitely get it, 2. Probably get it, 3. Probably not get it, and 4. Definitely not get it. Responses 1 and 2 were collapsed into 'High intention to vaccinate' and responses 3 and 4 were collapsed into 'Low intention to vaccinate'. The data table shows the number of participants with high intention to vaccinate. Please note we only report this outcome for those NOT reporting vaccination at 6 months
