For kittens, two vaccines given at 12 and 16 weeks, and then a booster one year later. Your veterinarian will recommend continued booster frequency based on your cat’s risk of exposure to FeLV.
This vaccine is highly effective for prevention of Feline Leukemia Virus (FeLV). FeLV is a very contagious and deadly virus that is shed in bodily fluids of cats and can be spread to a healthy cat or kitten if it comes into direct contact or shares food or water bowls with an infected cat. FeLV cannot be spread to humans or other species.
