Acute and delayed neurologic reaction to inoculation with attenuated live measles virus
Brain & Development
|January 1, 1985
Abstract:
A Japanese boy developed a high fever and a prolonged convulsion 11 days after inoculation with live measles vaccine. He had 4 more seizures during the next 6 mos. His EEG became transiently abnormal 14 mos later. Antimeasles complement fixation, hemagglutination, and neutralization titers were elevated.
Insights
A Japanese boy experienced prolonged seizures and fever following measles vaccination. Subsequent EEG abnormalities and elevated antibody titers suggest a possible vaccine-related neurological event.
Area of Science:
- Neurology
- Immunology
- Vaccinology
Background:
- Live measles vaccines are crucial for public health, but rare adverse events require careful monitoring.
- Understanding the potential neurological complications following vaccination is essential for patient safety.
Observation:
- A Japanese boy presented with high fever and prolonged convulsions 11 days post-live measles vaccine inoculation.
- The patient experienced four additional seizures within six months of the initial event.
- Electroencephalogram (EEG) abnormalities were transiently noted 14 months after vaccination.
Findings:
- Elevated antimeasles antibody titers (complement fixation, hemagglutination, and neutralization) were detected.
- The temporal association between vaccination, neurological symptoms, and serological findings suggests a potential link.
Implications:
- This case highlights the importance of continued surveillance for neurological adverse events following measles vaccination.
- Further research may be warranted to elucidate the mechanisms underlying such rare vaccine-associated neurological complications.
- Clinicians should be aware of the potential for delayed neurological manifestations after live measles vaccination.
