Two weeks ago, Elephas reported, “The True Story Behind the AI Cancer Vaccine That Shrunk a Dog’s Tumor by 75%.” Trigger warning: it’s about an mRNA ‘vaccine.’ But it’s not a vaccine, of course. It was a one-and-done genetic treatment, like we always said.
Paul Conyngham is a tech entrepreneur and data scientist in Sydney, Australia. He has no biology degree. He has no research lab. He has no medical degree or white coat. What he did have was a rescue dog named Rosie —a Staffy-Shar Pei mix— who was diagnosed in 2024 with aggressive mast cell tumors. Vets gave her a terminal diagnosis. Pharma companies denied Rosie compassionate access to experimental veterinary drugs.
But Paul loved Rosie. He refused to accept it.
He spent $3,000 to sequence Rosie’s tumor DNA at UNSW’s Ramaciotti Centre. He used ChatGPT as a research assistant, to analyze the tumor’s mutations and plan a neoantigen identification strategy. He used Google DeepMind’s AlphaFold to model the three-dimensional shapes of Rosie’s mutated proteins. He used Grok to design the treatment approach. Then he collaborated with researchers at UNSW’s RNA Institute to manufacture a personalized mRNA vaccine —a bespoke treatment specifically designed for Rosie’s unique tumor mutations— for a total cost of a few thousand dollars. (We’ll return shortly to the mRNA issue.)
In December 2025, Rosie received her first injection.
Within one month, her tennis-ball-sized leg tumor shrank by 75%. She was back to jumping fences and chasing rabbits. The vets called the results “astonishing” and one associate professor reportedly said: “It was like, holy crap, it worked.”
The UNSW team called it the first personalized cancer vaccine ever designed for a dog. OpenAI’s (ChatGPT) CEO Sam Altman called it “amazing.” Conyngham is now open-sourcing his data so other pet owner-hackers can replicate the approach. “Just a couple of decades ago,” Coyngham wrote, “it would have cost over a billion dollars. But it is rapidly coming down in price, while getting much, much faster.”
Regardless of what anyone thinks about mRNA vaccines, the real story is that a tech entrepreneur with zero biology training, using publicly available AI tools, designed his own personalized cancer vaccine for his dog that produced results competitive with multi-million-dollar pharmaceutical programs— for a few thousand bucks. And in only a few months, start to injection.
Can you see it yet? This is the garage startup moment for medicine. The personal computer was just built in a Sydney garage by a rescue-dog owner with a ChatGPT account.
Nobody has criticized mRNA covid jabs more than me. But I have no problem with personalized cancer treatments using that technology. If you’re dying of terminal brain cancer, potential long-term side effects from mRNA treatments are an irrelevant side issue. mRNA was originally developed for this purpose; it was never intended to be used as a broad ‘vaccine’ against common respiratory viruses.
Twenty years on, and there are no approved personalized mRNA cancer treatments in humans. But a Sydney tech bro just cured his dog using a chatbot.
