Poisoning by tetanus vaccine

This code represents an adverse reaction or poisoning specifically caused by the administration of a tetanus vaccine. This includes systemic toxic effects, allergic reactions, or other harmful responses directly attributable to the vaccine itself, rather than an infectious process.

Use this code when documentation clearly indicates a patient experienced an adverse event or poisoning due to a tetanus vaccine. This typically involves symptoms like anaphylaxis, severe localized reactions, neurological complications, or other systemic effects following vaccination. The physician's notes should explicitly link the symptoms to the tetanus vaccine.

• Always sequence this code as a secondary diagnosis following the code for the specific manifestation of the poisoning (e.g., anaphylactic shock, dermatitis).
• Do not use this code for vaccine underdosing, overdosing, or non-administration, which fall under different E-codes.
• Distinguish from allergic reactions to other vaccine components or general adverse effects of immunization not classified as poisoning.
