Advanced AI Tool EVEscape: Forecasting Emergent Viral Variants for Proactive Public Health Measures

Scientists from Harvard Medical School and the University of Oxford have engineered a sophisticated artificial intelligence algorithm, known as EVEscape, for the purpose of anticipating the advent of new viral mutations. Initially conceptualized on the foundation of another model, EVE, which was designed to predict the impact of gene mutations on human health conditions, EVEscape has been specifically calibrated to deal with viral mutations. This development holds the promise of transforming the fields of vaccine research, public health monitoring, and the rapid formulation of health policies.

EVEscape employs both evolutionary data and biological specifics to forecast prospective mutations and emergent viral strains.

This newly minted AI system, EVEscape, utilizes evolutionary patterns and biological data to foresee how viruses may adapt to dodge immune responses. The model has accurately anticipated variants of the COVID-19 virus that have been of the highest concern.

According to the researchers, the utility of this tool extends to informing the development of immunizations and treatments not only for SARS-CoV-2 but also for other rapidly mutating viruses.

Amidst the COVID-19 pandemic, the world has grappled with a ceaseless array of SARS-CoV-2 mutations, each presenting unique challenges to immune resistance. However, EVEscape offers a proactive approach to predicting these mutations before they surface.

EVEscape consists of two integral components: an evolutionary sequence model that anticipates possible viral changes, and a comprehensive set of biological and structural data about the virus in question. In synergy, these elements enable the algorithm to predict the most likely future mutations.

A recent study, published today in the journal Nature, reveals that if EVEscape had been operational at the onset of the COVID-19 pandemic, it would have successfully identified the most prevalent mutations and high-concern variants for SARS-CoV-2. Moreover, the tool has also provided accurate predictions for other viruses, such as HIV and influenza.

Currently, researchers are employing EVEscape to make real-time predictions about forthcoming SARS-CoV-2 variants, releasing bi-weekly updates on emerging strains. This information has the potential to guide the development of more effective treatments and vaccines, and the team is expanding the scope of the tool to include additional viruses.

Senior author Debora Marks, associate professor of systems biology at the Blavatnik Institute at HMS, stated that the ability to preemptively identify viral variations could be pivotal in the development of future vaccines and treatments.

The Transition from EVE to EVEscape

Initially, the model EVE was conceived to analyze gene mutations responsible for human diseases, utilizing a generative model that makes predictions based on vast evolutionary data across species. As the COVID-19 pandemic progressed, the research team recognized the necessity to adapt EVE into EVEscape to address the unpredictable nature of SARS-CoV-2 mutations.

The generative model from EVE was augmented with detailed biological and structural information about the virus, such as immune system target areas, allowing the algorithm to make more precise predictions about viral mutations.

Backtesting EVEscape

The study involved a retroactive application of EVEscape, using only the data available at the start of the COVID-19 pandemic. EVEscape’s predictive accuracy matched that of experimental methods, but exceeded them in speed and efficiency, since no waiting for antibodies to emerge was required.

Moreover, EVEscape identified which antibody-based treatments would become less effective over time and sorted through thousands of emerging SARS-CoV-2 variants to pinpoint those most likely to pose significant risks.

Sarah Gurev, a graduate student in the Marks lab from MIT, noted that quick assessments of new variants could aid in making timelier public health decisions.

Finally, the study showed that the utility of EVEscape extends to other viruses, including but not limited to HIV and influenza.

Implications for Future Treatments and Vaccines

Researchers are utilizing EVEscape to make ongoing predictions about SARS-CoV-2’s evolutionary path. They release bi-weekly updates on newly emerging variants and also make the complete code for EVEscape publicly accessible.

The tool is currently being tested on lesser-known viruses like Lassa and Nipah, which also pose significant risks. The data generated by EVEscape could be instrumental in creating resilient treatments and vaccines for a wide array of viruses.

The article, published in Nature on October 11, 2023, lists several other contributors and acknowledges funding sources, including the National Institutes of Health and other prominent organizations.

Debora Marks, who serves as an advisor for various biotechnology firms, and other researchers, have no conflicts of interest that could influence the study’s results.
