Every 10 Minutes in the United States, Someone Is Treated for a Potential Rabies Exposure1

The virus has a capacity to kill 99.9% of the people who become infected, making it one of the deadliest diseases in the world.2,3

The Rabies Virus

Once rabies enters the central nervous system, it is almost 100% fatal4

  • Human infection occurs when the virus is transmitted through the saliva of an infected animal either by a bite or scratch5
  • Once a person infected with the rabies virus becomes symptomatic (fever, headache, discomfort), no treatment is proven to prevent the progression to death.2

The Rabies Virus Is Sometimes Too Challenging for the Human Immune System to Fight2,4

  • Proper administration of KEDRAB human rabies immune globulin prevents the rabies virus from advancing into the bite victim’s central nervous system long enough for the vaccine to boost the patient’s own natural immune response.4,6
  • Because the incubation period for rabies in a given person cannot be readily predicted, delivering antiviral antibodies with a human rabies immune globulin, such as KEDRAB, as soon as possible after exposure is recommended. Delays are potentially lethal.4

Treatment of Patients Exposed to the Rabies Virus Is Time-Sensitive

The Five Clinical Stages of Rabies4,8*

IncubationProdromeAcute Neurological PhaseComaDeath
Duration5 days to >2 years0 – 10 days2 – 7 days5 – 14 daysVariable
Pain or paresthesias at bite site
Lack of coordination
CNS signs (paresis, paralysis)
Pharyngeal spasms
Marked hyperactivity
Pituitary dysfunction
Cardiac arrhythmia
Cardiac arrest
Intravascular thrombosis
Secondary infections

*Adapted from CDC Advisory Committee on Immunization Practices 2010.4

  • A variable incubation period exists between exposure to the rabies virus and the appearance of symptoms—usually 1 to 3 months, but it could vary from 5 days to more than 2 years4
  • KEDRAB® (Rabies Immune Globulin [Human]) should be given as soon as possible after exposure, but no later than 7 days after the first dose of vaccine6

  • Enhanced color packaging for clear identification of 2mL and 10mL dosage options
  • User-friendly vertical barcodes on vials for easier scanning

New KEDRAB packaging, with distinctive vial sizes and colors, designed to reduce chances of error

Over the next several months, you can expect to start receiving KEDRAB® (Rabies Immune Globulin [Human]) with enhanced product packaging, as pictured above. Products with new packaging will be shipped when available, and after distributors' current supplies become depleted. As such, it is likely you may not receive both the new 2mL and 10mL product packaging at the same time.
