Tetanus shot and Tdap: what to know

Tdap is a combination vaccine. The letters refer to tetanus, diphtheria, and pertussis, also called whooping cough. It is different from a preparation used for routine tetanus and diphtheria booster protection. Your clinician may consider your age, prior doses, pregnancy, wound type, and the local vaccination schedule when choosing a product.

Tell the vaccinator about previous vaccine reactions, allergies, pregnancy, immune problems, and medicines. Bring any record you have, but do not delay urgent wound care while searching for paperwork. After vaccination, remain where staff can observe you for the period they recommend. Soreness or tiredness can occur; fluids, rest, and a cool cloth may help. More detail is available in [Tetanus Vaccination](/treatments/preventive-care-and-vaccination/tetanus-vaccination/).

Seek emergency help for breathing difficulty, facial or throat swelling, widespread hives, collapse, or severe dizziness after vaccination. Arrange clinical advice for a worsening injection-site reaction, persistent fever, or symptoms that concern you. If you are asking about Tdap after a wound, the need for assessment depends on the wound and your recorded protection, not on the brand name alone.

Ask whether Tdap is the product suited to you, which previous doses count, and whether pregnancy, a wound, or a past reaction changes the plan.
