The Ragon Institute was founded in February 2009 through a $100 million gift – the largest gift in Massachusetts General Hospital (MGH) history – from the Phillip T. and Susan M. Ragon Institute Foundation. Administratively based at MGH, the Ragon Institute incorporates the work of the Partners AIDS Research Center at MGH. Instead of the typical academic approach, in which individual scientists work independently, the Ragon Institute includes engineering disciplines to facilitate new experimental approaches and incorporate fresh ways of viewing complex biological systems, with the goal of rapidly advancing innovative, interdisciplinary research to revolutionize the field of immunology. In 2012, the Ragon Institute launched FRESH (Females Rising through Education, Support, and Health) in South Africa to connect HIV vaccine research with efforts to reduce poverty, a major driver of infection. Based in a former black township near Durban, FRESH trains young women in life skills, computer skills, and HIV prevention, while also working to detect early HIV infections and advance biomedical understanding. The program has helped over 1,200 women, most of whom have stayed uninfected and moved on to jobs or school. In January 2013, the Ragon Institute completed its relocation to 400 Technology Square in Cambridge, Massachusetts. On March 21, 2013, researchers at the Ragon Institute of MGH, MIT, and Harvard University introduced a new method for identifying potential HIV vaccine targets. The team, led by Arup K. Chakraborty, developed a computational technique to analyze viral protein sequences, helping to identify weak points in viral strains that could be exploited for vaccine development. By understanding how different viral strains reproduce in the body, the researchers aim to design protein fragments (peptides) targeting these vulnerabilities, with plans to test them in animals. In 2016, Dr. Facundo Batista joined the Ragon Institute as Scientific Director, strengthening its research capabilities and commitment to advancing immunology. On May 2, 2019, Massachusetts General Hospital received a $200 million donation by Phillip T. (Terry) and Susan M. Ragon to endow the Ragon Institute of MGH, MIT, and Harvard. At the same time, researchers at Harvard Medical School, based at the Ragon Institute of MGH, MIT, and Harvard, identified specific amino acids in the HIV protein structure that are crucial for the virus's function and replication. They found that the immune systems of individuals who can naturally control HIV infection target these amino acids with CD8 T cells, even in those who don't carry the HLA-B protein variants typically linked to HIV control. The findings, published in Science. On July 17, 2019, Swiss lawyer Ursula Brunner made a $5 million donation to the Ragon Institute of MGH, MIT, and Harvard. The gift will create the Brunner Fund for Medical Discovery, Education, and Social Good, supporting the institute's FRESH Program. On April 22, 2020, researchers from MIT, the Ragon Institute of MGH, MIT, and Harvard, and the Broad Institute of MIT and Harvard identified specific cells that are more susceptible to infection by the
SARS-CoV-2 virus, which causes
COVID-19. By analyzing
RNA data from various cell types, the team pinpointed cells in the lungs, nasal passages, and intestines that express high levels of the two proteins that allow the virus to enter human cells. In April 2021, at the CROI conference, Xu Yu, M.D., from the Ragon Institute (a collaboration between Massachusetts General Hospital, MIT, and Harvard), presented groundbreaking findings about "elite controllers"—individuals with HIV who naturally suppress the virus without the need for medication. Among these controllers, two individuals suppressed the virus so effectively that no active virus could be detected in their systems, even at very low levels. At the same year, the Ragon Institute began construction on a new research facility, designed to provide expanded laboratory space, enhance collaboration, and support a growing community of scientists, engineers, and clinicians. On January 22, 2024, ReiThera Srl, the Ragon Institute, and
IAVI announced a collaboration to develop a novel HIV vaccine candidate. The vaccine will use ReiThera's GRAd vector and HIV T-cell epitopes identified by the Ragon Institute, with funding from the
Bill & Melinda Gates Foundation. ReiThera will handle vector engineering, process development, and GMP manufacturing, while the Ragon Institute will lead preclinical development. IAVI will sponsor and conduct a Phase 1
clinical trial to assess the vaccine's safety and
immunogenicity. On August 2024, Terry Ragon announced that he is funding HIV cure research through his Ragon Institute and donated around $400 million to the cause. Ragon has referred to this initiative as a "Manhattan Project on HIV," with clinical trials for a therapeutic vaccine scheduled for 2025. In November 2024, the Ragon Institute together with
Tecnológico de Monterrey signed an agreement to collaborate on doctoral studies, research programs, academic exchanges, and joint research projects to bring advanced immune system research to Latin America. On January 29, 2025, researchers at the Ragon Institute and MIT's Jameel Clinic developed MUNIS, a deep-learning model that improves
T cell epitope prediction. This model has the potential to accelerate vaccine development for infectious diseases. The findings were published in
Nature Machine Intelligence. == Facilities ==
