Dog's personalized cancer vaccine developed using AI and ChatGPT

A data engineer used AI tools including ChatGPT and AlphaFold with university researchers to design a personalized mRNA vaccine for his dog Rosie; the tumor reportedly shrank by about 75% after treatment.

Paul Conyngham, a data engineer, worked with researchers at two Australian universities to design a personalized mRNA cancer vaccine for his rescue dog Rosie after conventional treatments failed. He used AI tools to assist in analyzing the tumor and selecting targets while university teams synthesized and administered the vaccine. Rosie received injections in December 2025 and a booster in January 2026, and the tumor reportedly shrank substantially. Scientists involved have described the outcome as notable but have urged caution given the single-case nature of the result. Key facts: - Paul Conyngham used ChatGPT and other AI tools alongside academic researchers to guide the design of a personalized mRNA vaccine for his dog Rosie. - The UNSW RNA Institute synthesized the vaccine and it was administered under existing ethics approval at the University of Queensland in December 2025 and January 2026. - The tumor reportedly shrank by about 75% after treatment and Rosie showed increased energy. - Researchers note this is one dog and no controlled trial; they say human use would require years of trials and regulatory work. Summary: The case shows that AI-driven analysis plus mRNA technology was used to produce an individualized vaccine for a single canine patient with a reported large tumor reduction. Whether the approach can be extended to humans is undetermined at this time and will require extensive testing and regulatory processes.
