There is no scientific evidence to support the use of the vaccine. There are a group of ER physicians/toxicologists and veterinarians that are trying to bring order to the chaos that is current bite treatment. They have a group on facebook called Snakebite Support I recommend you read the science based treatment protocols and the rationale why it works. Many ER docs and vets have zero training in the correct current treatment of viper bites. Specifically antivenin and elevation of the bite area with fluid support and pain control are the principles of treatment. Common venoms are hemotoxic and neurotoxic. Antibodies from a vaccine do nothing to counter the effects. Bite responses are not allergic and Benadryl has no role. Being told to use Benadryl or antibiotics in the absence of signs of infection highlights the practioners lack of knowlege of current treatment regimens. Again reference National Snakebite Support on fb, print out the protocols and show your er doc or vet.
We read through the debate prior to making the decision to vaccinate our dog. It was the right decision for us.
I rembered the conversation at that time being clear that Benadryl was not effective and why I was asking questions again. As far as prophylactic antibiotics being administered following a poisonous snakebite I can't see any reason why you wouldn't do so. I know if I were bit I would damn sure want them.
