Emanuele Andreano is an immunologist and biotech innovator redefining how vaccines are discovered for pandemic threats. As Head of Serology and Immunology at the Fondazione Biotecnopolo di Siena and a leader in the European Vaccine Hub, he works at the intersection of AI, immunology, and global health. He pioneered Reverse Vaccinology 3.0, a breakthrough approach that can identify entirely new vaccine targets in days instead of years. In a first-of-its-kind demonstration, his team showed that artificial intelligence can predict unknown viral antigens directly from human antibody sequences—effectively reversing the traditional vaccine discovery process. His work spans monoclonal antibody discovery and next-generation vaccines against emerging pathogens, including mpox and SARS-CoV-2, with direct implications for global pandemic preparedness and biosecurity. Andreano has received international recognition, including the Antonio Feltrinelli Prize from the Accademia Nazionale dei Lincei, awarded in the presence of the President of the Italian Republic Sergio Mattarella, the IUIS Rising Star in Immunology, and a European Research Council (ERC) grant. He also co-directs a vaccinology program at the Institut Pasteur in Paris. “We are entering an era where vaccines can be discovered at unprecedented speed—transforming our ability to fight pandemics and save countless lives.”
