Failures of post-exposure rabies prophylaxis

Area of Science:

• Veterinary Public Health
• Infectious Disease Epidemiology
• Global Health Security

Background:

• Rabies is a significant public health concern, particularly in developing nations.
• Control strategies include canine rabies vaccination and post-exposure prophylaxis (PEP).
• Despite established protocols, PEP failures leading to rabies deaths are documented.

Observation:

• This study examines seven fatal rabies cases attributed to true PEP failures.
• Common deviations from World Health Organization (WHO) management recommendations were identified as frequent causes of failure.
• Lack of essential biologicals for PEP administration was also noted as a contributing factor.

Findings:

• True failures of rabies post-exposure prophylaxis, when WHO guidelines are strictly followed, are exceptionally rare.
• Most documented PEP failures are linked to non-adherence to WHO protocols.
• Inadequate supply or unavailability of crucial rabies biologics contributes to treatment failures.

Implications:

• Reinforcing adherence to WHO-recommended PEP protocols is critical for rabies prevention.
• Ensuring consistent availability of essential rabies biologics globally is paramount.
• Addressing management deviations can significantly reduce rabies-related mortality in at-risk populations.
