How does this work?
In the case of Covid, I understand (for some value of "understand") how they can make the cells create virus proteins, which then train the immune system without an actual infection to be ready for when the real virus strikes.
But if someone already has cancer cells, wouldn't all the proteins to train against already be in the body in the first place?
