First whooping cough vaccine: what to know

Whooping cough, or pertussis, is an infection that can cause prolonged coughing and breathing difficulty. Vaccination trains the immune system to recognise the infection and helps reduce the chance of severe illness and spread. Protection needs to be planned around age, pregnancy, previous doses, local recommendations, and health history. A vaccine does not treat an existing cough, so a person with symptoms may need separate assessment.

Bring your vaccination record if available and tell the clinician about previous reactions, allergies, pregnancy, immune conditions, and current illness. Ask which vaccine is being offered, when the next dose is due, and whether household members or caregivers need protection. A sore arm, mild fever, tiredness, or headache can occur after vaccination. Rest, fluids, and a suitable pain-relief option may help; check before taking medicine, especially for a child or during pregnancy.

Contact a clinician if a post-vaccine reaction is worrying, prolonged, or interfering with normal activity. Seek emergency care for breathing difficulty, swelling of the face or throat, widespread hives, collapse, or severe sudden illness. If a child develops repeated coughing fits, pauses in breathing, blue lips, difficulty feeding, or marked sleepiness, seek urgent help. Antibiotics may be used for confirmed infection, but they do not replace vaccination.

Ask when the first dose is recommended for the person being vaccinated, what protection is expected before later doses, and how to respond to a fever or cough afterward.
