European citizens are all exposed to an infodemic spreading increasingly which can severely impact their democratic participation and engagement. This may include disinformation, misinformation, fake news, and other types of interference on different issues related to public life. A pre-emptive approach needs to be taken to decrease the worsening impact, such as using vaccination against the spread of the pandemic. IMMUNE 2 INFODEMIC aims to immunise EU citizens/residents against disinformation and misinformation on selected themes by empowering and equipping them with several easy-to-use tools. The project consortium formulates and co-produces 3 instruments (vaccines): digital literacy, media literacy, and critical thinking; and applies these instruments to 3 selected hot themes (boosters): elections, COVID-19 and migration. The workshop aims to initiate the coproduction of the materials (videos, infographics, presentations) that will be used in events, workshops and e-learning settings against dis/misinformation. We aim to involve the experts and target group in the product design at the initial phase by bringing field experts, researchers, practitioners, media and communication experts, etc. together.
