Allergies

Is it possible for a Paranormal to have allergies? I don't mean like are werewolves allergic to silver or vampires allergic to sun. I mean can a werewolf be allergic to dust? Will pollen send a vampires to the medicine cabinet? Can a witch be allergic to cats? What do they do if they are? It definitely makes for a funny picture. I just see a vampire going down to the crypt and having sneezing fits cause his housekeeper forgot to dust. We always see these creatures and sexy and suave or scary and hunter like. But you rarely see them as sickly. Just a thought.
