The phenomenological movement has engaged with other sciences already since its inception in the works of Edmund Husserl and has continuously done so until this very day. For phenomenology the sciences have been not only an object of critical reflection and a source of inspiration to draw upon, but also a partner of a dialogue and even of mutual cooperation. One example of this has been phenomenology’s engagement with health sciences (medicine and psychiatry). Much of the attention in this engagement has been paid to elucidating the nature of illness and patient-health care professional relationship, as well as to describing specific illnesses and therapies. However, interestingly there has been little engagement with public health sciences that, among other things, deal with disease prevention and health promotion issues. This leads to questions: why it is so, whether there can be such a thing as the phenomenology of public health sciences and how could it look like? I will try to outline an answer to these questions within the context of the interdisciplinary research project I am currently conducting about vaccine hesitancy. During my presentation I will present preliminary results of the research and reflect upon the opportunities and limitations of the phenomenological approach to public health sciences.
