Q: How many doses are required?

For dogs, two vaccine doses (shots) are required one month apart for full effectiveness. For horses, three doses--each one month apart--are required.

Q: How long does it take for the vaccine to become effective?

It takes around 30 days from the last of two vaccine doses to gain maximum effectiveness. So, if rattlesnake season begins in your area around May, you should consider having your first dose in March and the second dose 30 days after that in April. For horses, three doses are required so, for the example above, the first dose should be administered in February, second dose in March, and the third in April to be effective in May.

Q: How long does the vaccine last?

If your dog is exposed to rattlesnakes for six months per year (given that winter is typically when rattlesnake retreat to their dens to hibernate), they will only need one booster per year about 30 days before the beginning of the rattlesnake exposure season. If your dog is exposed to longer rattlesnake seasons or year-round risks, they should be given a booster dose every six months.

Q: How do I get the Vaccine?

Contact your local veterinarian and ask for the Red Rock Biologics Rattlesnake vaccine. Most veterinarians are knowledgeable about the Red Rock Biologics rattlesnake vaccine and either have the vaccine on-hand or can acquire it quickly.
