Vaccination in pregnancy FAQs
Some vaccines, such as the inactivated seasonal flu vaccine and the whooping cough vaccine, are recommended during pregnancy to protect the health of you and your baby. An inactivated vaccine does not contain a live version of the virus it is protecting against.
Some vaccines, such as the tetanus vaccine, are perfectly safe to have during pregnancy if necessary.

Vaccines recommended in pregnancy
Flu vaccine
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 such as flu.
Pregnant women are more likely to get flu complications (such as pneumonia) 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, or if you do catch flu, it is less likely to be severe.

Whooping cough vaccine
Whooping cough can be 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 high levels of protection against serious whooping cough illness until they're able to have their whooping cough vaccination at 8 weeks old.
You usually have the whooping cough vaccine at 20 weeks pregnant, but you can have it from 16 weeks.
To give your baby the best protection against whooping cough, you should have the vaccine before 32 weeks of pregnancy. If for any reason you miss having the vaccine before 32 weeks, you can still have it later.
If you are 20 weeks pregnant and have not been offered the whooping cough vaccine, contact your midwife or GP surgery.

Respiratory syncytial virus (RSV) vaccine
Respiratory syncytial virus (RSV) is a common virus that causes coughs and colds. RSV usually gets better by itself, but it can be serious for babies.
RSV can cause serious lung infections (including pneumonia and bronchiolitis), which can make it difficult for babies to breathe and feed. These illnesses may need to be treated in hospital.
When you have the RSV vaccine in pregnancy, the protection from the vaccine is passed to your baby. This means your baby is less likely to get severe RSV for the first 6 months after they're born.
You should be offered the RSV vaccine around the time of your 28-week antenatal appointment. Getting vaccinated as soon as possible from 28 weeks will provide the best protection for your baby. But it can be given later if needed, including up until you go into labour.
Speak to your maternity service or GP surgery if you are 28 weeks pregnant or more and have not been offered the vaccine.
Vaccines not usually advised in pregnancy (live vaccines)
If a vaccine uses a live version of the virus, such as the MMR vaccine, 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. Your midwife, GP or pharmacist can give you more advice about vaccinations during pregnancy.
Live vaccines include:
- BCG (vaccination against tuberculosis)
- MMR (measles, mumps and rubella)
- oral typhoid
- yellow fever
Travel vaccines in pregnancy
When you're pregnant, it's best to avoid visiting countries or areas where travel vaccinations are required.
It may not always be possible to avoid areas that require vaccinations when you're pregnant. If this is the case, talk to a midwife or GP, who can tell you about the risks and benefits of any vaccinations you might need.
If there's a high risk of infection in the area you are travelling to, it's often safer to have a vaccine rather than travel unprotected as most diseases will be more harmful to your baby than a vaccine.
Which vaccines are recommended in pregnancy?
During pregnancy, your natural immune system is weakened to protect your pregnancy. This can mean you're less able to fight off infections. As your 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 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 own whooping cough vaccination at 8 weeks old.
