Researchers at the University of Cambridge used artificialartificial/ˌɑːrtɪˈfɪʃl/L2人造的；人工的made by humans, not by nature intelligence to design a new vaccine. The AI created the main part, and it has now undergone testing in people for the first time. The goal is a single vaccine that works against many coronaviruses, including future ones. Traditional vaccines train the body to fight one virus, but viruses mutatemutate/ˈmjuːteɪt/L2（生物）突变；变异to change the genetic structure of a living thing, often creating a new form and stop them. AI can analyze thousands of viruses and find stable parts to attack.
This vaccine uses DNAdnaL1一种存在于细胞核中的长线性聚合物，由核苷酸组成，呈双螺旋结构a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix instead of mRNA. As a result, it is more stable and easier to store. It can be given without a needle because a high-pressure stream of air delivers it through the skin. The trial showed the vaccine was safe and produced antibodiesantibodies/ˈæntɪˌbɒdiz/L2抗体proteins produced by the body to fight infections against several coronaviruses. However, the immuneimmune/ɪˈmjuːn/L2免疫的；有免疫力的protected from a disease, usually because the body has learned to fight it response was modest, and larger trials are needed to see if it can prevent infection.
A universaluniversal/ˌjuːnɪˈvɜːrsl/L2普遍的；通用的；全体的relating to everyone or everything; able to work for many different cases vaccine that works against many viruses is still a few years away. Also, this study shows that AI can help design vaccines that fight future pandemic threats. Scientists must do more research to confirm the vaccine's effectiveness and long-term protection.
