Pertussis advice before you travel
Pertussis is not a standard travel vaccine for UK adults, which is precisely why it repays a proper check rather than an assumption. Pregnancy, healthcare work, planned contact with a newborn, an active outbreak at your destination, or a childhood vaccination record you cannot reconstruct will each change the answer. The reason you are asking is usually as clinically relevant as where you are going.
A cough that spreads easily and can last for months
Pertussis is a bacterial respiratory infection. It spreads through droplets from coughing and sneezing, so it moves easily in homes, nurseries, aircraft cabins, family gatherings and healthcare settings. Early symptoms can look like an ordinary cold: a runny nose, mild fever and a cough. After a week or two, the cough can become more forceful and come in bouts that are hard to control.
The classic “whoop” can happen when someone gasps for breath after coughing, but adults and young babies do not always sound textbook. Some people vomit after coughing. Night-time symptoms can be worse. The cough may drag on for two to three months, which is why whooping cough has long been called the “100-day cough”.
For travellers, the main concern is not only catching it abroad. It is passing it to someone vulnerable. Babies under six months are at highest risk of severe illness, especially before they have completed their early infant vaccinations.
What the vaccine can and cannot do
Pertussis vaccination is given as part of combination vaccines rather than as a whooping cough-only jab. In the UK, babies receive pertussis-containing vaccines in early infancy, with a further pre-school booster. Pregnant women are offered a pertussis-containing vaccine from 16 weeks of pregnancy, ideally by 32 weeks, so antibodies can pass to the baby before birth.
For most travellers aged 10 and over, pertussis vaccination is not routinely recommended purely because they are going overseas. Exceptions may include pregnancy, some healthcare work involving regular contact with pregnant women or young babies, and outbreak-control advice from public health teams.
Protection is useful but not permanent. Neither previous infection nor vaccination gives guaranteed lifelong immunity, and there is no simple blood test that reliably proves you are protected. Side effects are usually mild, such as a sore arm, redness, swelling, tiredness or feeling generally off-colour for a day or two. Suitability should be checked if you are pregnant, have had a serious reaction to a vaccine before, are acutely unwell, or have a complex medical history.
Countries, newborn visits and outbreak situations
Pertussis occurs worldwide. There is no neat country list for whooping cough in the way there is for yellow fever certificates or some malaria recommendations. Cases can rise in countries with good vaccine programmes as well as in places with lower vaccine coverage, and several countries have seen increased activity again since pandemic restrictions ended.
A traveller visiting family in the United States, Canada, Australia or New Zealand may hear local advice about vaccinating adults who will be close to a newborn. UK guidance is more restrained: routine pertussis vaccination for adult travellers visiting newborns overseas is not currently recommended. The stronger UK focus is vaccination during pregnancy, plus keeping children up to date with their routine schedule and avoiding close contact with babies if you have respiratory symptoms.
Check the reason before chasing the jab
A short consultation removes a good deal of guesswork here. Bring your vaccination records, your travel dates, pregnancy details where they apply, and the specific reason pertussis has come up, because that reason shapes the advice more than the destination does. If a pertussis-containing vaccine is appropriate we will explain the timing; if it is not, we will tell you that instead, and why.
