INTERVENTION: Randomisation Participants will be randomised equally across conditions stratified by three levels of vaccine hesitancy (positive, very doubtful, strongly hesitant). Intervention conditions There are ten information conditions. Each specific added section (conditions 2, 3, 5, 6, 7, 8) has a word count within 20% of the mean. Data on the time that participants take to read each condition will be collected. The conditions are: 1. Control: a basic statement of safety and effectiveness taken from https://www.nhs.uk. This control statement features at the end of all other conditions. 2. Collective benefit I: adding the collective vaccination benefit of not personally getting the virus. 3. Collective II: adding the collective vaccination benefit of not transmitting the virus to others. 4. Collective III: adding the collective vaccination benefits of not getting ill and not transmitting (i.e. adding 2 and 3 together). 5. Personal benefit: adding the personal benefit of getting vaccinated. 6. Seriousness: adding the seriousness of pandemic. 7. Safety: directly addressing concerns about vaccine safety related to the speed of development 8. Safety: indirectly addressing concerns about vaccine safety related to the speed of development 9. Collective and personal: adding the collective and personal benefits together (i.e. adding conditions 4 and 5). 10. Full combination: adding the information on the collective and personal benefits, the seriousness of the virus, & the safety information that indirectly addresses the speed of development concerns (i.e. adding CONDITION: COVID‐19 (SARS‐CoV‐2 infection) vaccine hesitancy ; Infections and Infestations PRIMARY OUTCOME: COVID‐19 vaccine hesitancy is measured using the Oxford Covid‐19 Vaccine Hesitancy Measure at post‐randomisation SECONDARY OUTCOME: Beliefs about COVID‐19 and vaccination are measured using the Oxford Vaccine Confidence and Complacency Scale at post‐randomisation INCLUSION CRITERIA: 1. UK adults (age 18 or above), quota sampled to be representative for age, gender, region, education level, and ethnicity
