Diphtheria shot

Diphtheria-containing vaccines use harmless components to prepare the immune system to recognise the toxin. They are commonly combined with protection against other infections, so the product name may differ by age and vaccination history.

Vaccination lowers the chance of severe disease but does not treat an active infection. A sore throat with a throat coating, neck swelling or breathing difficulty needs clinical assessment; see [Sore Throat].

Bring the available immunisation record and tell the vaccinator about previous reactions, current illness, allergies and medicines. The clinician can recommend catch-up doses or a booster when records are incomplete or exposure has occurred.

After the injection, mild local soreness or short-lived fever may occur. Follow the clinic's advice about comfort measures and observe for symptoms that need urgent attention. More background is available in [Childhood Immunisation].

Call emergency services for facial swelling, wheezing, trouble breathing, collapse or widespread hives soon after vaccination. Contact the vaccination clinic for persistent or concerning symptoms. If diphtheria is suspected, seek care promptly rather than waiting for a vaccine appointment.

Ask which product is appropriate, whether a booster or catch-up dose is due, what reactions to expect, and whether recent exposure changes the plan. If infection is suspected, ask about [Antibiotic Treatment].
