One - health, environment, society - conference video contest

Changes to video contest rules

In order to facilitate access to the poster presenters’ videos and simplify the voting process, the video contest will be hosted on YouTube instead of Instagram, as previously announced. Submitted videos will be available on EFSA’s corporate YouTube channel for public voting from 1-28 February 2022. The three videos receiving the most ‘Likes’ will be the winners (more information below).

Please note that following the change of hosting platform, the contest Entry Requirements have been updated with the new technical specifications. All changes are underlined.
