It sounds to me from what Morty's told me that you have a very friendly universe which lets you get away with a lot of science and doesn't kill you, just occasionally drops novel sorts of magic on you to give you a new challenge. Where I'm from, vaccinations are a science fiction thing and anybody trying a stunt like that in real life is lucky if all that happens is they get the disease they were trying to ward off and find it mysteriously resistant to ordinary magical healing.
