What should you know about the pertussis vaccine and pregnancy?

Newborns are especially vulnerable to respiratory infections before their own routine immunisations are established. Vaccination during pregnancy can prompt antibodies that cross the placenta, giving the baby temporary early protection. The exact timing and product depend on local guidance, pregnancy history, current health, and previous doses, so the maternity team or vaccination clinic should confirm the plan.

The vaccine is designed to prevent pertussis; it does not cure an active cough. Learn about [Whooping Cough](/conditions/whooping-cough/) and remember that a [Cough](/symptoms/cough/) in pregnancy can have several causes.

Tell your obstetrician, midwife, or vaccinator how far along the pregnancy is, which vaccines you have received, and whether you have had a serious allergic reaction. Ask whether vaccination is recommended in your care setting and when it fits your antenatal appointments. Afterward, arm soreness, tiredness, headache, or a mild temperature may occur. Rest and follow advice about suitable medicines. If you have a persistent cough, seek assessment; [Antibiotic Treatment](/treatments/medical-management/antibiotic-treatment/) may be considered when clinically appropriate.

Seek emergency help for breathing difficulty, collapse, or swelling of the face, mouth, or throat after vaccination. Contact your maternity team urgently for severe illness, reduced ability to drink, or a cough that causes vomiting or breathing pauses. A [Fever](/symptoms/fever/) during pregnancy should be discussed when it is persistent, accompanied by worrying symptoms, or associated with feeling significantly unwell.

When should I receive the pertussis-containing vaccine? Does my previous dose change the plan? Which symptoms after vaccination are expected? How will my newborn be protected before routine infant vaccines?
