Quick read

Tetanus vaccines can be used in pregnancy.

What is it?

Tetanus can be a fatal illness and can be caught through skin injuries that happen outdoors, as well as animal bites. 

Tetanus is rare in the UK as most people are vaccinated against the disease.

A number of vaccines are used to protect against tetanus in the UK, including Repevax®, and Revaxis®, as well as ADACEL®, and Boostrix-IPV®, which also protect against whooping cough.

Benefits

What are the benefits of having a tetanus vaccination during pregnancy?

Tetanus vaccination can prevent the complications of tetanus, including death.

You might be offered a tetanus vaccine in pregnancy if:

•    You have not had a complete course of tetanus vaccinations (or do not know whether you have had a full course). You will be offered catch-up vaccinations to ensure you are fully protected. A full course is usually five tetanus vaccinations, starting when you were a baby.
 
•    You experience a ‘tetanus-prone injury’ - most commonly a deep puncture wound that happened outside, particularly if there was soil or manure around. Some animal bites or scratches might also need a tetanus vaccination. If you get a skin wound outside, or are bitten or scratched by an animal, phone your GP for advice about whether you need a tetanus vaccination. After these sorts of injuries, you might be advised to have a tetanus vaccination if your last tetanus vaccination was more than 10 years ago.

Risks

Are there any risks of having a tetanus vaccination in pregnancy?

No. Information from over 200,000 pregnant women who received tetanus-containing vaccines raises no concern of harm to the baby.

Alternatives

Are there any alternatives to having a tetanus vaccination in pregnancy?

No. If you need a tetanus vaccination it is important to have one as tetanus can be very serious. 

If you need a tetanus vaccination after week 16 of pregnancy, you can have a combination vaccine that also protects against whooping cough. This will help to protect your baby from becoming seriously ill if they catch whooping cough after birth. For more information, see the Bump leaflet on whooping cough vaccination in pregnancy.

If you have had a tetanus vaccination in early pregnancy, you should still have an extra whooping cough vaccine after 16 weeks of pregnancy to protect your baby. It is best to leave at least four weeks between the two vaccinations as this is thought to reduce the chance of an ‘injection site reaction’ - like a tender arm.

No treatment

What if I prefer not to be vaccinated against tetanus in pregnancy?

You can decline the vaccination. However, this is not advised as protection against tetanus is very important. Tetanus can be life-threatening and can cause problems with your jaw and neck muscles which can make it difficult to swallow and breathe.

Will my baby need extra monitoring?

No. The tetanus vaccine is routinely given in pregnancy and does not mean that any extra monitoring is required.

Who can I talk to if I have questions?

If you have any questions about the information in this leaflet, please discuss them with your health care provider. They can access more detailed medical and scientific information from www.uktis.org.

How can I help to improve drug safety information for pregnant women in the future?

Our online reporting system (MyBump Portal) allows women who are currently pregnant to create a secure record of their pregnancy, collected through a series of questionnaires. You will be asked to enter information about your health, whether or not you take any medicines, your pregnancy outcome and your child's development. You can update your details at any time during pregnancy or afterwards. This information will help us better understand how medicines affect the health of pregnant women and their babies. Please visit the MyBump Portal to register.

General information
Sadly, miscarriage and birth defects can occur in any pregnancy.

Miscarriage occurs in about 1 in every 5 pregnancies, and 1 in every 40 babies are born with a birth defect. This is called the ‘background risk’ and happens whether medication is taken or not.

Most medicines cross the placenta and reach the baby. For many medications this is not a problem. However, some medicines can affect a baby’s growth and development.

If you take regular medication and are planning to conceive, you should discuss whether your medicine is safe to continue with your doctor/health care team before becoming pregnant. If you have an unplanned pregnancy while taking a medicine, you should tell your doctor as soon as possible.

If a new medicine is suggested for you during pregnancy, please make sure that the person prescribing it knows that you are pregnant. If you have any concerns about a medicine, you can check with your doctor, midwife or pharmacist.

Our Bumps information leaflets provide information about the effects of medicines in pregnancy so that you can decide, together with your healthcare provider, what is best for you and your baby.
