What should you know about pertussis booster how often?

Pertussis protection can change over time, and recommendations are not identical for every person. The relevant schedule may depend on doses received in childhood, previous adult boosters, pregnancy, work with infants, travel, an outbreak, or medical conditions. A booster is different from treatment for an active cough. Vaccination lowers the chance of illness but does not explain every cough or replace assessment when symptoms are severe. Keep a record of vaccine names and dates where possible; an immunisation clinic can help reconstruct an uncertain history.

Ask a vaccination clinic, family doctor, or pharmacist to review your record rather than guessing the interval. Mention pregnancy, plans for pregnancy, allergy history, immune conditions, and any previous reaction. If you have a cough, fever, or known exposure, tell the clinician before attending so they can advise on infection precautions. Do not delay urgent care while searching for records. Household members who spend time with a newborn may also need a personalised prevention discussion. Childhood immunisation records can be useful when reviewing a later booster plan.

A booster does not treat breathing difficulty. Seek emergency help for severe breathlessness, blue or grey lips, collapse, confusion, or chest pain. Arrange prompt assessment for coughing fits, vomiting after coughs, dehydration, or a cough that is rapidly worsening. Contact a clinician soon after a significant exposure, especially if you are pregnant, care for a young baby, or have lung disease.

Which pertussis-containing doses are on my record? Do I need a booster now? Does pregnancy or close contact with a baby change the advice? What should I do after an exposure? Can I be vaccinated if I have a current cough?
