We produced four short films to be used as part of a study on HIV vaccine misinformation. Designed as an “information vaccine” to build early resistance to common misinformation tactics, the videos use a TikTok-style format to appeal to young urban African women. It features a performer of a similar demographic who acts as a relatable influencer. Through dynamic storytelling, the film warns, previews, and refutes misleading claims, empowering research participants to recognise and reject falsehoods before encountering them. Our creative approach combined behavioural science with youth-led storytelling to deliver content that is both authentic and effective.
