AI Tool Speeds Up Vaccine Development Process


— January 29, 2025

AI tool MUNIS accelerates vaccine development by improving T cell epitope prediction.


A recent breakthrough from the Ragon Institute and MIT’s Jameel Clinic is changing vaccine development. By combining expertise from immunologists and tech experts, a new AI tool called MUNIS has been created to predict immune system responses with a level of accuracy that could speed up vaccine creation for diseases like HIV, influenza, and Epstein-Barr virus. This tool can predict specific parts of viruses that our immune system recognizes, called T cell epitopes, which are essential for triggering targeted immune responses. Unlike older methods, which were slower and less reliable, MUNIS uses machine learning to sift through large amounts of data much faster and more accurately. The tool has already shown impressive results, identifying new, potentially immune-boosting epitopes in viruses that scientists had been studying for years.

The MUNIS system was developed through a collaboration between Dr. Gaurav Gaiha from the Ragon Institute and Dr. Regina Barzilay from MIT. Their partnership brought together the latest advancements in AI and immunology to tackle the challenging task of identifying T cell epitopes. The team was able to train MUNIS using a huge database of human leukocyte antigens, which are critical for recognizing pathogens. By feeding this data into an AI tool, MUNIS was able to find new patterns and predict T cell epitopes much more effectively than previous models.

One of the most exciting aspects of MUNIS is its ability to predict epitopes with the same accuracy as traditional lab tests, which are often time-consuming and expensive. This means that researchers could potentially skip some of the labor-intensive steps in the lab, saving both time and resources. In addition to influenza and HIV, MUNIS was also tested on Epstein-Barr virus (EBV), a virus linked to various cancers and autoimmune diseases and was able to identify new potential targets for immune therapies.

The results have been encouraging, and the team believes MUNIS could eventually help in designing vaccines and therapies for a wide range of infectious diseases. But the potential of this tool doesn’t stop at infectious diseases. MUNIS could also play a key role in cancer treatments and autoimmune disorders. By predicting the immune system’s response to cancer cells, for example, MUNIS could help in developing more effective immunotherapies. Similarly, it could aid in understanding and treating autoimmune diseases, where the immune system mistakenly attacks the body’s own cells.

The development of MUNIS is just the beginning. This project is part of a broader initiative called the Mark and Lisa Schwartz AI/ML Initiative at the Ragon Institute. This initiative is focused on bringing together AI and machine learning with immunology to create more powerful tools for fighting infectious diseases. Thanks to the generous support of Mark and Lisa Schwartz, this initiative has the resources to continue expanding on this groundbreaking work.

Both Dr. Gaiha and Dr. Barzilay have expressed excitement about the possibilities that lie ahead. Dr. Gaiha emphasized how the collaboration between computer scientists and immunologists was key to developing the tool, saying that each team brought essential insights to the table. Dr. Barzilay, on the other hand, highlighted the promise of AI in understanding the complex ways our immune system works, which could revolutionize how we tackle diseases in the future.

The launch of MUNIS marks an important step in the intersection of technology and medicine. As more diseases emerge around the world, tools like MUNIS offer hope for faster and more efficient vaccine development. With the ability to predict immune responses more accurately and quickly, MUNIS could pave the way for quicker vaccine rollouts, saving lives and reducing the global impact of infectious diseases. This achievement is a prime example of how innovation in AI and immunology can work together to tackle some of the world’s most pressing health challenges.
