During pregnancy, your immune system is naturally weaker than usual. This means you are more likely to have certain infections and illnesses that can be harmful to you and your developing baby.
Vaccination is the safest and most effective way of protecting pregnant women and their babies against serious diseases such as whooping cough, flu and COVID-19.
The pertussis vaccine (which protects against whooping cough) and flu and COVID-19 vaccinations are recommended in pregnancy to help keep you and your baby safe.
