With the Covid 19 epidemic, it has been observed that untrue news about issues such as the size of the epidemic, the origin of the disease, the ways of transmission, diagnosis and treatment, both in Turkey and around the world, spread rapidly. As a result of this, the World Health Organization, one of the most authoritative institutions on the Covid 19 epidemic, has named this situation "infodemia". The start of Covid 19 vaccination studies in Turkey as of December 2020 has led to the rapid spread of many infodemic information about the vaccine. The general purpose of this study is to determine the effect of false, false and conspiracy theory information and news about the Covid 19 vaccine on the decision of Samsun University students to be vaccinated. In the study, 'questionnaire' was used as a data collection technique. The questionnaire prepared in the digital environment was sent via short message to all students at Samsun University and the data of 517 questionnaires answered between 29.07.2021 and 16.08.2021 were used in the study. The collected data were analyzed quantitatively and the remarkable answers to the open-ended questions in the questionnaire were added to the research findings and interpreted. As a result of the research, it was revealed that Samsun University students were generally worried about the fake news about the Covid 19 vaccine, and this news affected their decision to be vaccinated.
