The tetanus toxoid vaccine, which is used to protect against tetanus, can sometimes lead to neurological adverse events, particularly in individuals who have previously experienced such reactions. This could include conditions like Guillain-Barré Syndrome or other serious neurological disorders, where a previous exposure to the vaccine has led to complications.

In the case of severe hypersensitivity, a patient who has had a documented anaphylactic reaction to a previous tetanus vaccination or its components should not receive the vaccine due to the risk of a similar severe reaction occurring again.

Other conditions such as local side effects, muscular spasm, and pregnancy do not universally contraindicate the administration of tetanus toxoid. Local side effects, while common, do not prevent further vaccinations. Muscular spasm may be a symptom that suggests further investigation is needed, but it isn’t an outright contraindication. Additionally, pregnancy is not a contraindication for tetanus toxoid, as it is considered safe for use during pregnancy when indicated.
