Vaccinations were and will remain a major advance in medicine, and the prevention of infectious diseases by vaccination is a milestone that we can be proud of and whose effectiveness must continuously be defended. With this article we do not want to repeat the extensive basics of vaccination medicine again; in this regard, reference is made to the relevant literature and in particular to the recommendations of the Robert Koch Institute. From our point of view, we address relevant knowledge about the daily vaccination practice of dermatological patients and focus on a summary of everyday highly relevant questions. In particular, we would like to offer argumentative aids to the time-consuming discussions with doubting and sceptical patients that are well known and feared in everyday clinical practice.
