Communication is a fundamental form of connection in society. Within the scientific framework, the topic of communication is covered in almost all areas, from economics, sociology, law to health. A special segment of the study of communications relates to communication with vulnerable groups in society. The aim of this paper is, based on professional and scientific literature and previous research, to systematize knowledge about communication, social and communication inclusion as well as market communication to vulnerable groups in society. A review of the literature shows that there is no universal or common definition of vulnerability, but all definitions of vulnerability are associated with the risk of marginalization. Vulnerable people show weakness, fragility and inability to recover from unexpected real but also potential problems. Whether an individual belongs to a vulnerable group or not, he is an individual with his own needs and values. Values refer to the stable life goals that people have, reflecting what is most important. An important segment in understanding the inclusion of individuals is also their needs. Inclusive communication is an approach that enables the inclusion of as many people as possible, and to better understand communication inclusions, it is necessary to know the assumed communications with each of the categories of vulnerable groups. In this paper, emphasis is placed on the following vulnerable groups: children and youth, the elderly, the poor, the under-educated, people with disabilities and migration and refugees. The basic roles of advertising are to provide all the necessary information about the company, production, purpose and use of the product; strengthening product recognition and desirability; and creating preferences and encouraging product use. Marketing sometimes creates controversy and concern. The biggest criticism usually involves targeting vulnerable or vulnerable consumers with controversial or potentially harmful products. One of the key tasks of studying and applying ethics in advertising and marketing communication is to ensure the protection of vulnerable groups in society.
