Tetanus, diphtheria and pertussis vaccine

The vaccine presents the immune system with selected, non-infectious parts or instructions related to tetanus, diphtheria, and pertussis. This helps the body recognise these threats later. Tetanus can follow a contaminated wound and affect muscle control. Diphtheria can damage the throat and release toxin. Pertussis can cause persistent coughing, with particular concern when it reaches a young infant. Protection can lessen the chance of severe illness, but vaccinated people can still develop symptoms and should seek assessment when they are unwell.

Bring your immunisation record and list any serious allergies or reactions to earlier doses. Tell the clinician about pregnancy, immune-system conditions, recent fever, and medicines that may affect the decision. Stay for the observation period advised by the service. Arm soreness, redness, tiredness, or a mild fever may occur afterward; use the service's advice about comfort measures and follow-up. [Antibiotic Treatment](/treatments/medical-management/antibiotic-treatment/) is separate from vaccination and is used only when a clinician prescribes it for a suitable infection.

Get immediate help for difficulty breathing, fainting, severe dizziness, or swelling of the face, mouth, or throat after vaccination. Arrange medical advice for a reaction that is severe, worsening, or not settling, or for a new sore throat with breathing or swallowing difficulty. If a wound is deep or contaminated and your vaccination history is unclear, seek prompt advice rather than waiting for symptoms.

Ask which doses are recorded, whether a booster or catch-up dose is appropriate, what reactions are expected, and how pregnancy or a health condition changes the plan. Ask where to report a concerning reaction and what to do after a future wound or exposure.
