Introduction: Solid organ transplantation evolved from an experimental procedure in the early 20th century to a treatment option for patients with end-stage organ dysfunction. The availability of organs for all  patients in need of transplantation is limited by several factors, among which social ones play a key role. Therefore increasing awareness of transplantation, and its ethical, legal, and cultural aspects, is a significant method of the donor pool increase. The study aims to present the “Second Life” social campaign conducted in Poland for 16 years, which successfully promotes the transplantation idea in cooperation with hundreds of secondary school students every year.
Methods: The campaign is dedicated to young people (secondary school students) across the country. The goal of the campaign is to encourage teenagers to start a discussion about transplantation with their family members, school peers, and neighbors. The method of transplantation promotion is up to the students, which makes them very creative and committed. They share  knowledge about the value of organ donation and transplantation  online and through various events organized at school and in the neighborhood.
All students get  medical training provided by transplant experts (physicians, nurses), legal training conducted by a lawyer, and ethical one, usually delivered by clerical people. During the training, particular attention is paid to  presumed consent for donation and the role of the declaration of will to donate organs after death as a document helpful in discussion with a potential donor family. Campaign participants share declarations of will and encourage everyone to sign them and keep them in their wallets.
Results: Over the 16 years of running the “Second Life” campaign, 950 secondary schools participated in the project across the country and about 450, 000 students actively promoted the idea of transplantation among their social circles. Nearly 1,5 million distributed declarations  will surely increas the number of potential donors and transplantation procedures in Poland. Each school, student, and local government institution involved in the project spread the word on transplantation in their social media; events organized locally attract media – which gives the campaign a lot of publicity.
Conclusions: Social campaigns play an important role in the increase of transplantation awareness in society. Involving teenagers in the project makes the campaign interesting, creative, and well-received by society. Each year more schools want to participate in the project, which proves that the campaign is needed and has the potential to grow. Transplantologists praise the idea and are keen to get involved in the project whenever it is needed. Although it is impossible to assess the results of the campaign in terms of the exact number of transplantation increases, it is still a vital way to give people knowledge to make a conscious decision on whether to donate their organs.
