Vaccines literally never cure anything. That's not how they work.

Vaccines would have to prevent cancer, which is damn near impossible.

Moreover, cancer isn't a fucking virus. You can't inoculate someone against cancer because it's a defect in the cell's genetic code.

I'm willing to bet this man literally doesn't know anything about what that mRNA injection is or does.

My guess is that the mRNA injection is a GENE THEREAPY which tries to combat the malformed genes of the cancer cells.

Again, giving them the benefit of the doubt, it's still not a vaccine.
