”Det er ikke en vaccine – det har været planlagt og organiseret længe”

This article explores the phenomenon of an-ti-vaccine conspiracy theories, which have deep roots but have gained renewed attention in the aftermath of the COVID-19 pandemic. Employ-ing the concepts of pseudoscience, stigmatized knowledge, and denialism, it examines the argu-ments within these theories and argues that traditional methods such as debunking have limited effect. The main idea of the article is that belief in conspiracy theories is not merely due to a lack of knowledge but requires a deeper understanding of the underlying psychological motivations. It analyzes the online networks behind the dissemination of anti-vaccine conspiracies during the COVID-19 pandemic and discusses potential societal and health consequences. Finally, it pre-sents a practice-oriented approach for healthcare professionals to communicate with patients who are attracted to conspiracy beliefs. A nuanced approach is advocated, one that recognizes the complexity of beliefs and the social and psycho-logical needs that sustain them through a non-judgemental dialogue.
