No data? https://www.cancer.gov/news-events/cancer-currents-blog/2022/mrna-vaccines-to-treat-cancerSome have said if asked if they would take a cancer vaccine would say no.

At least cancer isn't contagious. Pity that those ignorent fucks would still insist that the government pay for their chemo. Just because out of ignorance they wouldn't take a shot that has been tested and approved for use. Keep in mind we are not talking about people who have been unable to overcome a food or tobacco addiction, just a simple fucking shot.
They are already doing mini trials. Will they succeed? Like any research maybe not. But maybe in 4-5 years they will succeed.
