The role of new dengue vaccines in curtailing the emerging global threat of dengue outbreaks arising from mass gathering sporting and religious events

The risk of outbreaks of arthropod-borne pathogens arising from mass gathering events is ever increasing due to the rising number of travellers from arbovirus endemic areas, and the expansion and adaptation of arthropod vectors such as mosquitoes worldwide due to climate and environmental change [1-4]. Indeed, introduction of dengue virus (DENV) was a concern at the recent Olympic Games in Paris 2024, Japan 2020 and Brazil 2014 but outbreaks did not happen [5-7].
