Data were collected as part of the After the End project, which investigates lived experiences in the aftermath of diseases, disasters, and other global health crises once they are officially declared to be ‘over’.  A cross-sectional, correlational design was used to assess factors associated with vaccine intent, which was analysed as a binary outcome: being less or more likely to have a COVID-19 vaccine in the future. The primary independent variable was perceived temporal proximity. Covariates included age, gender, direct COVID impact/risk variables (having long-COVID, having a health condition perceived as increasing vulnerability to COVID-19, or being a carer for someone vulnerable), and trust in government. Participants were adult UK residents recruited through Prolific.com, an online research platform where individuals opt in to take part in studies. Recruitment used Prolific’s “Representative Sample” feature, which applies census matched quota sampling to ensure that the sample reflects UK population distributions for age, gender, and ethnicity. Because Prolific distributes studies directly to eligible users, a conventional response rate was not calculated. The questionnaire was available for one day, on 8 March 2025, with no reminders issued.
