Like another poster said, it's not really common for a horse to be killed by the actual bite. Most of the time, they are bit on the nose and what kills them is the swelling because it swells their nostrils closed and they suffocate.
In all the years we've lived in Texas (smack dab in the middle of rattler country), we've had a lot of horses get bitten...only one died. She got bit on her neck, where it meets her jaw, right there close to that large vein. She didn't recover in spite of everything the vet did to save her.
All that said, I had never heard of a vaccine for bites so I don't know if it would be any help or not. I guess the thing you need to do is ask yourself if the cost, questionable efficiency (all vaccines are questionable), and possible side effects are worth it to try it out.
Always remember that feeling of looking at a big, open country over the ears of a good horse, seeing a new trail unwind ahead of you, and that ever-spectacular view from the top of the ridge!!! Follow my training blog: http://robertsontraining.blogspot.com/
