I would not do it unless I saw more than one large study done that proved it's value in at least 80% of the cats used in the studies. Like I've said many times before, I don't believe in the FELV vaccine at all, any normal adult cat will develop the immunity against FELV in time anyways, so the vaccine is, IMO, worthless, because it's only doing what time would do to begin with. In addition, with the increased risk of VAS with the FELV vaccine, it's just NOT worth the risks to vaccinate ANY cat with the FELV vaccine. Period. Giving the FELV vaccine to a cat that already HAS FELV is doing nothing but increasing the cat's chance of getting a VAS (vaccine associated sarcoma). I will keep this stance until proven otherwise by scientific studies.
The only time I advise for any cat to get the FELV vaccine is if the negative cat is going to be directly exposed to the FELV virus (like if you know you are going to mix a negative young cat with a positive one), and the cat is under 1 1/2 years old, and there's NO way to prevent the exposure. (really, not the case very often) Also worth saying again, ALL vaccines should be given as low as possible in the rear leg, in case a VAS develops, that way amputation can be done, and you can save the cat's life. Never ever ever ever allow your vet to give any vaccine in the scruff of the neck or back, or along the side of the cat's body where amputation of the injection site would not be possible!
