Sensorimotor polyneuropathy after hexavalent vaccination.

Area of Science:

• Pediatrics
• Immunology
• Neurology

Background:

• Routine infant immunizations are crucial for public health.
• Hexavalent vaccines (INFANRIX hexa) protect against six common childhood diseases.
• Adverse events following immunization are typically mild and infrequent.

Observation:

• A previously healthy infant received the first dose of hexavalent vaccine (INFANRIX hexa).
• Two weeks post-vaccination, the infant presented with severe sensorimotor polyneuropathy.
• The infant's neurological symptoms significantly impacted motor function.

Findings:

• The infant developed severe sensorimotor polyneuropathy temporally associated with hexavalent vaccine (INFANRIX hexa) administration.
• Despite the severity of the neurological condition, the infant showed a positive response to treatment.
• Complete recovery of sensorimotor function was achieved through intensive physiotherapy.

Implications:

• This case highlights a rare but serious potential adverse event following hexavalent vaccine (INFANRIX hexa) immunization.
• Early recognition and intensive rehabilitation are critical for managing vaccine-associated neurological complications.
• Further research may be warranted to understand the specific mechanisms and incidence of such rare events.
