[In Focus] Perspectives of potential haematopoietic stem-cell donors on education TikToks

TikTok is a rapidly growing social media platform on which users develop, interact with, or share short vertical videos (TikToks). Although TikToks have immense potential to be harnessed to affect health knowledge, attitudes, and behaviours, little research guides TikToks’ potential public health applications. Since 2020, we have led the development and use of a large TikTok library to engage diverse young adults to haematopoietic stem-cell donation. This library, including hundreds of TikToks starring diverse performers, has generated hundreds of thousands of views and engagements across social media platforms.
