A Guy Used ChatGPT to Build a Custom Cancer Vaccine for His Dog and It Actually Worked
When vets said there was nothing more they could do, an Australian tech entrepreneur turned to AI and ended up making medical history.
This story sounds like science fiction, but it's 100% real.
Paul Conyngham, an Australian tech entrepreneur, had a dog named Rosie who was dying of cancer. Traditional treatments weren't working. The tumors kept growing. Vets basically told him there was nothing left to try.
So he did what any desperate tech guy would do: he asked ChatGPT for help.
ChatGPT suggested immunotherapy and pointed him toward the University of New South Wales Ramaciotti Center for Genomics. From there, Conyngham used a combination of ChatGPT, Google's AlphaFold (an AI that predicts protein structures), and genomic analysis to work with scientists to design a completely personalized mRNA cancer vaccine for his dog.
And here's the wild part: it worked. One week after the first shot, Rosie's tumor started visibly shrinking. By January 2026, she had enough energy to jump a fence at the dog park chasing a rabbit. Just a month earlier, she could barely move.
This isn't just a feel-good pet story. It's a glimpse of what personalized AI-driven medicine might look like for humans in the near future. If a guy with a laptop and some AI tools can design a custom cancer vaccine in his spare time, imagine what a fully funded research lab could do.
