There's no advantage. The saliva of the tick just happens to contain a sugar molecule that's also in Red meat and it sets off quite a significant immune response resulting in the affected acquiring a new "allergy" (unwarranted immune response) to the meat. It should theoretically fade with time, but the immune system is a complex beast and works slightly differently in every human.
