Which cat rabies vaccine?
The three year vaccine is prepared with an adjuvant which can cause fibrous sarcoma, a kind of cancer. The adjuvant is added to the vaccine to boost its effectiveness but can cause a whole host of problems. We discovered this the hard way and lost a beloved cat to the disease years ago. It’s definitely worth getting the one year vaccine which doesn’t use the adjuvant. See this also here and here Hunting through these links I see that it’s an issue for Feline Leukemia vaccine as well as rabies – for rabies I believe the safe alternative is called “purevax”.
