The paper deals with human cultural stereotypes embedded in mythological consciousness, which have influenced the formation of fear of vaccination against COVID-19. The material was collected in Ukraine in the period from September 2021 to January 2022. By analysing oral narratives and comments from social media users, the authors demonstrate the cultural mechanisms of fear of vaccination, specifically fear of death and fear of metamorphosis, and how they can be overcome. The profusion of memes, anecdotes, and jokes that people read and shared on social media or told each other became a way of overcoming collective fear. Nowadays, not only oral tradition but also social media can constitute a source for studying cultural stereotypes. A folkloristic and culturally anthropological perspective on the fear of vaccination allows us to trace folkloristic phenomena back to our everyday lives and to see folklore as a living, dynamic process that has become part of human culture.
