Remarkable healing stories, such as that of Romuald, known as the ‘Geneva Patient’, highlight potential new treatments for previously incurable diseases. Romuald’s HIV was rendered undetectable after a unique bone marrow transplant, despite lacking a common resistance gene. Meanwhile, José Vidal overcame a life-threatening lung infection through phage therapy, which uses viruses to target antibiotic-resistant bacteria. Additionally, Beatrice Thurnherr’s successful immunotherapy for metastatic melanoma underscores advancements in cancer treatment. These unusual cases could pave the way for further research and development in medical therapies.
