Australian IT entrepreneur Paul Cuningham developed an experimental mRNA vaccine to treat cancer in his dog, Rosie, after standard therapies proved ineffective, according to The Australian. He conceived the idea during a discussion about treatment options with the AI chatbot ChatGPT.

Cuningham sequenced the DNA of the tumor, compared it with the genome of healthy cells, and used AI tools to identify mutations that could serve as targets for immunotherapy. He then collaborated with scientists who synthesized a personalized mRNA vaccine based on this information.

After administration, Rosie’s tumors noticeably shrank within a few weeks, although complete remission has not yet been achieved. Currently, the owner and researchers are working on a new version of the vaccine to target the remaining tumors.

Scientists emphasize that this is an experimental case, but it demonstrates the potential of personalized mRNA vaccines, which in the future could also be used to treat cancer in humans.
