cqvip:Introduction. Anti- tetanus vaccination is considered to bevery safe. However complications such as mononevritis,multinevritis or even polyradiculonevritis can be encountered.Observation. An 85- year- old man was admitted to our unit after a traffic accident caused by stroke. Seventy- two hours later thepatient developed tetraplegia within a few hours, caused by neuropathy secondary to anti- tetanus vaccination. Discussion.In this elderly patient, the rapid onset and severe presentation of the tetraplegia as well as the past history of normal vaccination and the axonal form of the neuropathy could have led to a misdiagnosis of neuropathy after booster- anti- tetanus vaccination. We first ruled out other possible diagnoses and then reviewed the possible mechanisms of neurological complications of vaccinations. These complications are probably underestimated in elderly hospitalized patients who receive a booster shot in the emergency department. Conclusion. This report illustrates the importance of reconsidering the benefit/risk relationship of anti- tetanos vaccination.
