AI-designed mRNA vaccine shrinks a dog’s cancer in world-first study

A Sydney tech entrepreneur used ChatGPT to help design a personalised mRNA cancer vaccine for his rescue dog Rosie. After sequencing Rosie’s tumour and collaborating with UNSW researchers, they produced a bespoke vaccine that, after December and January injections, halved the tumour and improved her quality of life. Described as the first canine personalised cancer vaccine, the work raises hope for human applications, though ethical approvals, costs, and partial responses mean it is not a cure yet and more testing is planned.
