Curious...did you have a vaccinated dog get bitten, and then die?
What is the basis for your comment ?
Our vet in Oregon was once "the" doc researching snake/dog interactions at UofAz (Michael E Peterson, DVM, specialty toxicology, if your vet is under 50 likely wrote the book he/she used on the subject). Most interesting was that in over 2000 dogs bitten by snakes that they treated while he was teaching there, there were only two or three that died. His explanation was that most dogs don't even see the snake, run past it, the snake is surprised and bites defensively with a "dry" bite. On the other hand, if you have three weenie dogs surrounding the snake on the back porch, nothing good is on the way.
The vaccine is based on one rattler species, and when studying the venom of rattlesnakes you find that they venom composition varies geographically, and often quite significantly. Second, the vaccine is enzymatic, not an infectious agent. Vaccines don't work on poisons, they work against an
infectious agent. You get your tetanus shot to protect you against the bug, so it can't set up and generate the poison that locks you up.
The concept
is appealing. But you don't find blinded studies (we don't put dogs in cages to get bit and see if they die), and the scientific premise for the vaccine is off base. And, to repeat myself, a dog vaxxed againsts rattlers in this county very possibly and even likely is not going to be "vaccinated" against the venom in two counties over where you may have toted your dogs to go bird hunt. But people pay the $$ anyway, because it can't hurt, right? But it isn't going to do any good - all of the anectdotal statements that "got my dog the shot, he got, bit, took him to the vet, and he lived" do not come close to describing causation if they even describe a relationship. And, when you get the "vaxx" for your dog, you still are told to rush them to the vet for treatment if they get bit. Hmmmm....
Doc laughed at me when I called and asked about getting my dogs shots. He basically said if I want to donate the $ to the local vet and the snake oil maker, I could feel free to do so. But he said it was worse than useless - folks place faith in it, take their dogs out in places / seasons they shouldn't, and can potentially lose their dog (or at least get everyone's day ruined).
