Indications

DEFENSOR® 1 helps protect dogs, cats and ferrets from rabies for 1 year; annual revaccination with a single dose.

DEFENSOR® 3 helps protect dogs, cats, cattle,* sheep* and ferrets from rabies. Revaccination is required every 3 years for dogs and cats, and annually for cattle, sheep and ferrets.

Vaccine Information

DEFENSOR vaccines contain inactivated rabies virus from an established cell line.

  • Contains a highly immunogenic fixed strain of rabies virus that originated from Louis Pasteur’s original 1882 isolate and has been extensively tested for freedom from contaminating agents.
  • In a field study with 2,647 doses of DEFENSOR 1 and 3 administered to canines:1
    • 96.2% were administered with no vocalization.
    • 99.9% were administered with no lameness, stiffness, hypersensitivity reactions or injection site reactions for 21 days after vaccination.
  • DEFENSOR vaccines produced for sale in California meet specific potency standards required in that state.
  • Field Safety and Efficacy data supporting the ferret claim was approved by the USDA.

The Risk of Rabies

  • Infection of any mammal with rabies virus is almost always deadly.
    • Immediate euthanasia is recommended for unvaccinated dogs, cats and ferrets exposed to a known rabid animal.
    • If the owner is unwilling to have this done, the animal should be placed in strict quarantine for six months and vaccinated one month before being released.2
  • Prevalence: Cats have remained the most frequently reported rabid domestic animal (followed by dogs) since 1992.2
  • Progression to death is rapid: There are currently no known antiviral drugs effective against rabies.4
