Immunotherapy is currently the most well-studied form of cancer therapy. Cancer vaccines are promising but they only sparsely made it to the clinic. Immune checkpoint inhibition and CAR T cell therapy are also developed as cancer immunotherapy. Both of these have stellar reputations in the treatment of cancer. The goal of this meeting is the interaction – and knowledge exchange – between a series of big-shots in these immunotherapy fields with a broader group of young scientists making a career in these research fields. The subject of the conference is straight in the heart of biomedical science.
