Vaccination and pregnancy: During pregnancy

Vaccines you need during pregnancy
Vaccinations during pregnancy protect both you and your developing baby from serious infections. They also help protect infants after birth, when they're too young to be vaccinated.
If you're pregnant, you should be vaccinated against whooping cough (pertussis) and flu. Talk to your health care provider or local public health authority about making sure your vaccines are up to date.
You should get the following vaccinations during pregnancy. They're safe and help protect you and your baby.
During flu season, anyone who's pregnant or planning to become pregnant should get the flu shot. The flu is more likely to cause severe illness during pregnancy because your body goes through many changes. These changes can:
- affect the immune system, heart and lungs
- make it harder for your body to fight off infections
Receiving the flu vaccine during pregnancy extends protection to your baby. This is important because babies younger than 6 months can't get vaccinated against the flu. Your flu shot helps protect your baby from the flu after birth.
Vaccination with a non-live flu vaccine lowers the risk of complications from the flu during pregnancy and after your baby is born. However, live (attenuated) flu vaccines shouldn't be given during pregnancy.

Tdap (tetanus, diphtheria, pertussis) vaccine
During each pregnancy, you should get the Tdap vaccine, even if you've received it before. You should get it when you're between 27 and 32 weeks pregnant.
Whooping cough (pertussis) is particularly dangerous for infants under 2 months of age because they're too young to be vaccinated. When you get the Tdap vaccine in pregnancy, you produce antibodies that protect your newborn during the first months of life.
