The search for alternative knowledge, conspiracy theories, distrust of expertise and anti-science movements are gaining momentum and post-truth populism is speeding up on the back of fake news. The crisis of truth refers to an era where evidence and objective facts get lost in sentiment, emotion, and personal beliefs. Relying on emotions, creationism, religious beliefs, and common sense over expertise deliberately creates counter-knowledge referred to as pseudo-science, troll-science or fake-science. As the worth of scientific expertise is devalued, the counter-scientific discourses supported through populist political rhetoric help to produce a culture of resistance to science. Our qualitative content analysis of Twitter posts along with the news regarding anti-vaccine arguments from two selected online news sites, revealed three major themes, which we referred to as strategies used by the COVID-19 vaccine deniers in Turkey to disseminate their views. These were: an emphasis on bodily freedom and personal choice and the use of “my body my choice” rhetoric; the denying, devaluing, and shifting of scientific evidence; and the dismissal and/or attacking of alternative views and the deepening of the polarisation between the supporters of the COVID-19 restrictions, vaccine supporters and deniers. We conclude the paper by arguing that there is a link between the distrust of doctors and the anti-vaccination ideas, and the quest for alternative knowledge and expert authority
