Vaccine FeLV positive cat?

Species: Cat
Breed: long hair
Age: 2-5 years
If my cat tested positive for FeLv should he still get vaccine boosters like fvrcp, aren't those dangerous, are they "alive" or "dead"? Also can i give a cat who has Fiv the FeLv and fvrcp boosters? Actually to be simple: can a cat with a weak immune system receive those boosters? Will those give him the "unwanted" disease? Thank you

Dr. Marie replied:

We definitely do recommend vaccinating a cat who is positive for feline leukemia. The vaccine will not be harmful to him and will help to protect him from further disease. If he were to come in contact with another virus this could be deadly.

There probably is no benefit in giving feline leukemia vaccine to Gready, but I would give the rest of his vaccines. A while back there was a study that suggested that the Feline Leukemia vaccine would help prevent FeLv positive cats from getting lymphoma but this is not believed to be true anymore.

Ultimately though, I would follow the recommendation of your vet as he or she will know what is best for Gready.

I dont know if Gready has Fiv or not but i want her to get vaccinated especially for FeLv and fvrcp, so my question was: is it dangerous for her to get those vaccines if she may have Fiv..? I know i can make her tested, but lets say i dont, will it be harmful for her to get those vaccines?

Dr. Marie replied:

Ah, I understand your question now. No, there will be no harm to Gready if she gets any of her vaccines even if she does have FIV. In fact, when we know that a cat is positive for FIV we still will vaccinate them.

Hope that helps!

Dr. Marie.
