About immunisation and pregnancy

Some infectious diseases can cause serious harm to pregnant women or their unborn babies. If you are planning to have a baby, try to get up to date with your routine immunisations before you become pregnant.

All women should receive influenza and whooping cough vaccines during every pregnancy.

Serious side effects or allergic reactions to vaccines are rare.

For more information watch the Maternal immunisation video by Safer Care Victoria.

Risk of infectious diseases during pregnancy

Some diseases can harm you and your unborn baby if you become infected with them when you are pregnant.

Examples of infections that are harmful to pregnant women and unborn babies include:

• COVID-19 – the risk of severe illness due to COVID-19 is significantly higher for pregnant women and their unborn babies.
• Rubella – can cause defects in the baby's brain, heart, eyes and ears and increases the risk of miscarriage and stillbirth.
• Chickenpox – can cause defects in the baby's brain, eyes, skin and limbs.
• Measles – increases the risk of miscarriage, premature birth or stillbirth.
• Mumps – increases the risk of miscarriage.
• Hepatitis B – can cause acute hepatitis B infection that you can pass on to your baby during birth. Both you and your baby could then become 'carriers' of hepatitis B (if the virus is not cleared from the body).
• Influenza – increases the risk of miscarriage, premature birth or stillbirth. and your risk of severe illness and death.
• Whooping cough (also known as pertussis) – can cause pneumonia, seizures, encephalopathy and the death of the baby.

As well as being immunised, you can reduce your risk of catching infectious diseases during pregnancy by:

• washing your hands regularly
• avoiding international travel
• avoiding close contact with sick people.

Immunisation before pregnancy

If you are planning for a baby, preparations you can make include:

• Visit your doctor for a health check-up. The doctor will order a blood test to check your immunity to some diseases (including rubella, chickenpox and hepatitis B) to see if you are protected. Based on the results, the doctor may recommend vaccination.
• If you are not up to date with any of your routine immunisations, ask your doctor about catch-up doses.
• Ask anyone else living in your house to be up to date with their immunisations to reduce their risk of passing diseases on to you and your baby.
• Avoid getting pregnant for at least one month after having the measles, mumps and rubella (MMR) vaccine or the chickenpox vaccine.

Immunisation during pregnancy

Having the influenza and whooping cough vaccines during pregnancy is the best way you can protect your unborn baby. When you are immunised, your antibodies transfer from you to your developing baby. They receive protection in the first months of life when they are too young to be vaccinated.

Influenza infection can cause serious complications in pregnant women that can affect the unborn baby. Whooping cough (pertussis) infection can cause serious complications in babies, including death. This is why it is recommended that you are immunised against whooping cough and influenza during every pregnancy.

Influenza immunisation is free and recommended at any time during pregnancy.

Whooping cough combination* vaccine is free for pregnant women from 20 weeks gestation during every pregnancy. It is recommended that pregnant women have the whooping cough combination vaccine between 20 and 32 weeks gestation, but it can be given up until delivery.

You can get a COVID-19 vaccine if you are pregnant, breastfeeding or trying to fall pregnant.

There is no evidence that these vaccines will harm your unborn baby.

[*Note: The whooping cough combination vaccine is known as the ‘three-in-one dTpa vaccine’. It immunises you against whooping cough (also known as pertussis), diphtheria and tetanus.]

Immunisation after pregnancy

If you didn’t get the chance to get all your routine immunisations up to date before becoming pregnant, see your doctor after you have given birth.

If you are fully immunised, it will:

• help protect your newborn against infection
• reduce the risk of illness and birth defects if you become pregnant in the future.

It is safe to be immunised while you are breastfeeding – it will not cause harm to your baby.

Immunisation from an early age is highly recommended for all Australian children. Having your baby immunised helps to protect them from the most serious childhood infections, some of which can cause death.

Immunisation and HALO

The immunisations you may need are decided by your health, age, lifestyle and occupation. Together, these factors are referred to as HALO.

Talk to your doctor or immunisation provider if you think you or someone in your care may need immunisation, based on their HALO. You can check your immunisation HALO using the Immunisation for Life infographic below.
