The flu jab in pregnancy

During pregnancy, your immune system (the body's natural defence) is weakened to protect the pregnancy.

This can mean you’re less able to fight off infections. As the baby grows, you may be unable to breathe as deeply, increasing the risk of infections such as pneumonia.

These changes can raise the risk from flu – pregnant women are more likely to get flu complications than women who are not pregnant and are more likely to be admitted to hospital. Having the flu vaccine means you’re less likely to get flu.

Whooping cough vaccination in pregnancy

Whooping cough is a very serious infection, and young babies are most at risk.

 Most babies with whooping cough will be admitted to hospital.

When you have the whooping cough vaccination in pregnancy, your body produces antibodies to protect against whooping cough. These antibodies pass to your baby giving them some protection until they’re able to have their whooping cough vaccination at 8 weeks old.

Pregnancy and COVID-19

If you're pregnant, or think you might be, it's strongly recommended you get vaccinated against COVID-19 to protect you and your baby.

You’re at higher risk of getting seriously ill from COVID-19 if you’re pregnant. If you get COVID-19 late in your pregnancy, your baby could also be at risk.

It’s safe to have the vaccine during any stage of pregnancy, from the first few weeks up to your expected due date. You do not need to delay vaccination until after you have given birth.

The COVID-19 vaccines do not contain any live viruses and cannot give you or your baby COVID-19

RSV vaccination

From 1 September 2024, pregnant women can have a free vaccine in each pregnancy, to protect their babies against respiratory syncytial virus (RSV).

RSV is a common virus which can cause a lung infection called bronchiolitis. In small babies this condition can make it hard to breathe and to feed.

Vaccines not usually advised in pregnancy (live vaccines)

If a vaccine uses a live version of the virus, you’ll usually be advised to wait until after your baby is born before you get vaccinated. This is because there’s a potential risk that live vaccines could cause your unborn baby to become infected. But there’s no evidence that any live vaccine causes birth defects.

Sometimes, a live vaccine may be used during pregnancy if the risk of infection is greater than the risk of the vaccination.

Live vaccines include:

• BCG (vaccination against tuberculosis)
• MMR (measles, mumps and rubella)
• oral polio (which forms part of the 6-in-1 vaccine given to infants)
• oral typhoid
• yellow fever
