Encephalitis following purified chick embryo rabies vaccination

Area of Science:

• Neurology
• Immunology
• Vaccinology

Background:

• Rabies vaccination is crucial for preventing a fatal zoonotic disease.
• Purified chick embryo cell (PCEC) vaccine is widely used, but rare adverse events are documented.
• Neurological complications following vaccination require careful monitoring and reporting.

Observation:

• A 6-year-old boy received the third dose of PCEC rabies vaccine.
• The patient presented with clinical features indicative of encephalitis post-vaccination.
• The child's neurological symptoms were consistent with vaccine-associated encephalitis.

Findings:

• The case demonstrates a rare instance of encephalitis following PCEC rabies vaccination.
• The patient experienced a complete recovery from the neurological adverse event.
• This highlights the importance of recognizing and managing rare vaccine complications.

Implications:

• Clinicians should be aware of the potential for rare neurological adverse events following rabies vaccination.
• Prompt diagnosis and supportive care can lead to favorable outcomes in vaccine-associated encephalitis.
• Continued pharmacovigilance is essential for understanding the safety profile of rabies vaccines.
