Using Generative AI to Anticipate and Prepare for the Next Pandemic

The rapid evolution of viruses, as starkly demonstrated by Covid-19, presents a formidable challenge in the realm of public health. The virus’s progression from beta to delta to omicron variants kept the world in a prolonged state of alert, with scientists racing to adapt vaccines and treatments. In this ever-evolving battleground, humanity often found itself lagging, constantly trying to catch up to the virus’s next move.

However, a groundbreaking AI developed by Harvard University, named EVEscape, might offer a strategic advantage. Described as a machine “oracle” for viral evolution, EVEscape has shown remarkable promise in predicting future viral mutations. Its development represents a significant leap in our ability to foresee and prepare for viral threats.

 

EVEscape was trained using data gathered before the pandemic, enabling it to predict not only frequent mutations of Covid-19 but also to generate a list of potential future variants of concern. The AI operates on a generative model akin to those powering DALL-E or ChatGPT, but uniquely incorporates various biological factors to mirror viral mutation patterns more accurately.

 

What sets EVEscape apart is its broad application spectrum. The tool can predict variants for various viruses, including influenza, HIV, and other less-studied viruses that pose potential pandemic risks.

 

Dr. Debora Marks, who spearheaded the study at Harvard Medical School’s Blavatnik Institute, emphasized the potential impact of this tool. “If we can anticipate virus variations and forecast new variants, that would be immensely valuable for designing future-proof vaccines and therapies,” she noted.

 

The development of EVEscape is timely, given the critical need for long-term forecasts in viral evolution. Unlike previous models that provided short-term predictions based on existing variants, EVEscape delves into evolutionary genomics, offering a longer and more comprehensive outlook.

 

This approach is akin to archeologists examining skeletal remains to understand evolutionary paths. EVEscape scrutinizes DNA sequences encoding proteins across species, uncovering genetic variants crucial to health. By applying this method to viruses, the AI can identify mutations critical for a virus’s survival and those likely to result in dangerous variants.

 

In its initial test with SARS-CoV-2, EVEscape’s predictions included spike protein changes, which have been central to vaccine and antibody therapy development. The AI’s predictions have since been validated against the GISAID database, with many of its top forecasts corresponding to variants observed during the pandemic.

 

More than a tool for combating Covid-19, EVEscape’s capabilities extend to other viruses with pandemic potential, such as the Lassa and Nipah viruses. By predicting mutations that could evade antibody treatments, EVEscape positions itself as a key player in the fight against future outbreaks.

 

The implications of EVEscape’s development are profound. For the first time, we have a tool that allows us to anticipate and prepare for viral mutations. Its application in predicting the next SARS-CoV-2 variant and other potential pandemic viruses could dramatically change our approach to public health crises.

 

As we continue to navigate the challenges posed by evolving viruses, EVEscape stands as a beacon of hope. It exemplifies how combining AI with evolutionary genetics can empower us to stay ahead in the fight against pandemics, potentially ensuring that Covid-19 remains the last of its magnitude in human history.
