It is recommended that all pregnant women receive one dose of whooping cough vaccine from 20-32 weeks.
The aim is to boost antibodies in vaccinated women in late pregnancy, so that whooping cough (pertussis) antibodies are passed from mother to baby. This is considered the best way to provide passive protection to infants in the first weeks of life and offers women a safe way to protect their baby against this serious disease.
