Allergic to cats? A new vaccine could help

There may be new hope for people who love cats but get all sniffly and sneezy whenever they’re around.

Cat allergies are usually caused by the protein Fel d 1, which is found in a cat’s skin, saliva and urine, reports Smithsonian. When a cat cleans itself by licking its fur, the saliva is then chock full of the protein. It dries on the cat’s fur and soon becomes airborne. About 10% of people are allergic to pets.
