Post Vaccination Guillain Barre Syndrome: A Case Report

Area of Science:

• Neurology
• Immunology
• Public Health

Background:

• Guillain-Barre syndrome (GBS) is a rare, potentially fatal autoimmune disorder.
• Infectious agents like Campylobacter jejuni are common triggers, but vaccines can also induce GBS.
• Older, neural tissue-derived rabies vaccines, though cost-effective, are associated with a higher GBS risk.

Observation:

• This case report details a young girl presenting with GBS symptoms including lower limb weakness, urinary retention, and abdominal pain.
• The patient received a neural tissue-derived anti-rabies vaccine prior to symptom onset.
• This presentation is consistent with vaccine-associated Guillain-Barre syndrome.

Findings:

• Neural tissue-derived rabies vaccines pose a risk for Guillain-Barre syndrome.
• Early diagnosis and adherence to WHO post-exposure treatment guidelines are crucial for rabies prevention.
• There is a lack of data on GBS incidence following vaccination in regions like Pakistan, suggesting underdiagnosis.

Implications:

• Increased awareness of vaccine-associated GBS is needed, particularly concerning older rabies vaccine formulations.
• Further research is required to establish the incidence and risk factors for GBS post-vaccination in diverse populations.
• Improved diagnostic protocols and vaccine safety monitoring are essential for public health, especially in resource-limited settings.
