ELI5 how exactly you teach the immune system to attack something? I mean, let's say immune system is a dog. Let's say that cancer is a cat entering the house (the body). Now, the problem is that normally the dog wouldn't attack the cat. Now, with a vaccine you are putting a stuffed cat in the house to have the dog attack it and learn that behavior. What I don't understand is how you tell the dog that the stuffed cat must be attacked.
