Tetanus, diphtheria and pertussis shot

Tetanus is linked to contaminated wounds and can produce jaw stiffness and muscle spasms. Diphtheria can affect the throat and produce a harmful toxin. Pertussis can cause prolonged coughing and may be dangerous for infants. A combined shot places protection against these illnesses in one vaccination visit when appropriate. It cannot treat an infection that is already established, and it does not prevent every cause of cough, sore throat, or wound infection. Your clinician checks age, previous doses, health conditions, pregnancy, and prior reactions.

Take your vaccination record to the appointment and mention allergies, previous serious reactions, immune problems, pregnancy, fever, and current medicines. After the shot, soreness, redness, tiredness, or a mild fever can occur. Rest, drink fluids, and follow the advice given by the vaccination service. Ask how to report a reaction and when another dose may be needed. For childhood schedules, see [Childhood Immunisation](/treatments/preventive-care-and-vaccination/childhood-immunisation/).

Call emergency services for trouble breathing, collapse, widespread hives with swelling, or swelling of the lips, tongue, or throat after a shot. Contact the vaccination service or a clinician for a fever that is worsening, severe weakness, persistent vomiting, or symptoms that concern you. A sore throat or cough after vaccination may have another cause; seek assessment if breathing or swallowing becomes difficult.

Ask which formulation is suitable, whether your record shows the required protection, what side effects are expected, and when to seek help. Also ask whether another vaccine or a wound-related dose is needed for your particular situation.
