The raw unstructured text extracted from online comments was converted to a structured dataset using Natural Language Processing Techniques. Traveller personas were defined using K-means based on the online survey results, with cluster (i.e. persona) descriptions made from the most discriminant features in a distinguished set of observations. The web-scraped profiles were mapped to the personas identified. Travel and vaccine-related behaviours were described for each persona.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>We identified ~2.6 million comments; ~880\u00a0k were unique and mentioned ~280\u00a0k unique trips by ~65\u00a0k unique profiles. Most comments were on destinations in Europe (37%), Africa (21%), Southeast Asia (12%) and the Middle East (11%). Eight personas were identified: \u2018middle-class family woman\u2019, \u2018young woman travelling with partner\u2019, \u2018female globe-trotter\u2019, \u2018upper-class active man\u2019, \u2018single male traveller\u2019, \u2018retired traveller\u2019, \u2018young backpacker\u2019, and \u2018visiting friends and relatives\u2019. Purpose of travel was leisure in 82\u201394% of profiles, except the \u2018visiting friends and relatives\u2019 persona. Malaria and rabies were the most commented diseases with 12.7\u00a0k and 6.6\u00a0k comments, respectively. The \u2018middle-class family woman\u2019 and the \u2018upper-class active man\u2019 personas were the most active in online conversations regarding endemic disease and vaccine-related topics, representing 40% and 19% of comments, respectively. Vaccination rates were 54%\u201371% across the traveller personas in the online survey. Reasons for vaccination reluctance included perception of low risk to disease exposure (21%), price (14%), fear of side effects (12%) and number of vaccines (11%).<\/jats:p>\n
