Pancreatic cancer forms on and is generally preceded by a series of pancreatic lesions, and the participants were only people with a history of medically concerning pancreatic lesions and a genetic predisposition to pancreatic cancer.

It’s also a cure- that was how it was (so far successfully) first tested, and they’re only now testing it as a vaccine.

This seems less like a vaccine for pancreatic cancer and more like a vaccine for the cause of pancreatic cancer, like HPV's relationship with cervical cancer. A subtle, but important difference, as that's less experimental than "a vaccine for cancer".

Although, targeting precancerous lesions that were created by their own body is still rather more experimental than targeting a completely foreign virus.
