人工智慧研發出突破性疫苗，協助克服未來疫情！

Researchers at the University of Cambridge have created a new type of vaccine using artificial intelligence. This is the first time that the main part of a vaccine has been designed completely by AI and then tested in people. The scientists hope this vaccine can protect against all types of coronaviruses, including those that cause Covid and others that could cause future pandemics. They are also working on similar vaccines for the flu and Ebola.

Vaccines work by teaching our immune systems to recognize and fight off infections. However, some viruses, like the flu and coronavirus, can change their appearance quickly. This means vaccines can become less effective over time, which is why we need new Covid and flu shots every year. Professor Jonathan Heeney, who leads the Cambridge team, says their goal is to make vaccines that work even if the virus changes or if a new virus jumps from animals to humans. To do this, the researchers used AI to study the genetic codes of many different coronaviruses. The AI then designed a 'super-antigen,' which is a special part of the vaccine that helps the immune system recognize and fight a whole family of viruses, even if they mutate.

The first tests of the vaccine were done with 39 people to check if it was safe. The results showed that the vaccine was safe and caused a small reaction in the immune system. Now, a larger study with about 200 people is being done to see how well the vaccine works. Other scientists are excited about this new way of making vaccines. Professor Saul Faust, who helped with the trials, says the AI design has a lot of potential. The Cambridge team is also testing vaccines for the flu and Ebola in animals. Experts believe that using AI could make vaccine development much faster and more effective, which could help prevent future pandemics and save lives. Science Minister Lord Vallance called this a great example of how British science and AI can work together to create new treatments for people around the world.
