Scientists develop first-ever “broad-spectrum” bird flu vaccine using AI

Scientists used AI to design a vaccine capable of protecting against a wide range of bird flu variants. That’s a game changer for national biosecurity and more resilient public health systems, they say. Scientists at Cambridge University have developed a new vaccine using Artificial Intelligence that targets multiple strains of bird flu in one shot, rather than providing immunity to one variant. The jab could protect even from variants that haven’t

Scientists develop first-ever “broad-spectrum” bird flu vaccine using AI

In brief

Researchers at the University of Cambridge used AI to design a single vaccine aimed at many bird flu variants. In mice and ferrets, it completely protected against a range of genetically distinct viruses that have all caused human infections. Only half the animals survived those viruses when given the World Health Organization's existing bird flu vaccine.

Current pandemic preparedness relies on stockpiling vaccines against individual variants that have already emerged. Bird flu is an RNA virus, which can mutate quickly, jump from animals to humans and evade the protection of existing vaccines. The team says its approach is designed to anticipate viral evolution rather than react to it.

The results come from animal studies published in Cell Reports Medicine. The vaccine has not yet been tested in people, and the next step is human clinical trials.

Main points

  1. The study was published in Cell Reports Medicine and led by Jonathan Heeney of the Lab of Viral Zoonotics at the University of Cambridge.
  2. The team used bird flu sequence data from surveillance programmes worldwide, covering wildlife, livestock and infected humans.
  3. Computational and evolutionary algorithms produced five AI-optimised synthetic antigens representing the global diversity of bird flu viruses.
  4. Mice and ferrets were completely protected against genetically distinct variants that have all caused human infections.
  5. Only half of the animals immunised with the WHO's existing bird flu vaccine survived exposure to the same viruses.
  6. The vaccine was developed by the University of Cambridge and its company DIOSynVax Ltd.

The gain

In a Cambridge animal study, an AI-designed bird flu vaccine fully protected mice and ferrets against genetically distinct variants, while only half the animals given the WHO's existing vaccine survived.

The full story

The researchers gathered genetic sequence data on bird flu viruses recorded by surveillance programmes worldwide. They then used computational and evolutionary algorithms to design five synthetic antigens meant to cover the global diversity of the virus and to stop it evading immune protection.

In animal tests, the vaccine gave full protection to mice and ferrets against several genetically distinct variants, all of which have infected people. Animals immunised with the WHO's existing vaccine fared worse, with only half surviving. Heeney said AI speeds up vaccine design, after which candidates are tested in the lab for safety.

The next step is human clinical trials, so the vaccine could be available in an outbreak. The team also wants to extend the framework to seasonal influenza vaccines and other rapidly evolving RNA viruses. Earlier this year it developed what it describes as the first fully AI-designed vaccine to be tested in humans, aimed at viruses such as Ebola and coronaviruses.
