To my surprise my cat (Puff) got a rabies vaccine that is only good for a year. I was surprised as I thought the trend these days was away from frequent vaccines so I was initially miffed.
But the vet told me that this is a vaccine that works different than the usual vaccine. The usual vaccine was, I think, "adjuvant" type in that it caused an inflammatory response that then stimulated the immune response to the rabies virus. These, he said, are possibly associated with tumor growth and so he gives cats a different kind that works differently...I remember something about a parrot being part of the story.
The up side is that the vaccine my cat got does not produce a potentially harmful inflammatory response.
The down side is that the immune response wears off faster and so you have to have them vaccinated more often.
Anyone ever heard of this?
Also I am wondering, if non adjuvant rabies vaccines are possibly harmful, what should our dogs be getting?
