Immunisation for pregnant women

Immunisation against influenza and whooping cough is important to help protect you and your unborn baby, and to pass your protection to your baby after they are born.

Immunisation against influenza and whooping cough during pregnancy is recommended by the Ministry of Health, and free. Talk to your doctor or practice nurse, or your midwife to find out how to protect you and your child. 

Mothers pass some of their immunity along to their babies during pregnancy. This provides some protection to newborn babies during the first few weeks of life until they are able to be immunised.

Title: Immunise against influenza during pregnancy

[Sam] Here.

[Ali] It goes there – how about that one?

[Ali to camera]

The young people I’ve seen that have um had the flu have got very, very sick.

And quite surprisingly, you always think if you’re young you’ll get the flu and you’ll be fine within a day or two.

But I’ve looked after people that have been in ICU for six weeks and they were very young and um  almost died.

And also looked after a pregnant lady who was sick.

[Text on screen - Why is it important to immunise during pregnancy?]

[Ali] I got the flu vaccination while I was pregnant for two main reasons.

[Ali and Sam continuing to play and Ali talking direct to camera.]

One is because I don’t want to be sick looking after a new baby, and also um to protect my child. When they’re newborn they’re quite vulnerable to everything that’s out there and I couldn’t bear, couldn’t bear looking after a child that was sick knowing I could have done something to prevent it.

One thing that made me strongly get, flu vac while I was pregnant was I helped care for a lady who was about my age and she was quite pregnant, almost due to have her baby, and she was very, very sick.

She almost died. She was with us for quite a few weeks.

[Text on screen - In recent years, New Zealand pregnant women were five times more likely to be admitted to hospital for influenza-related complications than women who were not pregnant.]

[Ali] And just watching her and what her husband was going through, and it was their first baby and it was meant to be an exciting time.

She almost died. Her husband was visiting her everyday worried about the baby and her, and then when she finally delivered her baby as an emergen he was left with this beautiful newborn and a wife who was still terribly sick and was going to take months to recover and I just thought, I don’t want that to ever be me, or my husband.

Influenza

Influenza during pregnancy can harm you and your unborn baby. Women who catch influenza during pregnancy have higher rates of pregnancy complications, including premature birth, stillbirth, and babies who are small for gestational age. New Zealand research shows that healthy pregnant women are nearly five times more likely to be admitted to hospital when suffering from influenza complications than women who are not pregnant.

Influenza immunisation is safe given during any stage of pregnancy. There is no increased risk of reactions to the vaccine for pregnant women and you cannot get influenza from being immunised. The influenza vaccine will not harm your unborn baby. The vaccine simply stimulates your own immune system to make antibodies that can fight off the virus. 

The good news is that once you have immunity, you can also pass it on to your baby naturally, which has been shown to decrease the chances of your newborn getting the flu. Newborns and young infants have higher rates of influenza and hospitalisation than other children, so the protection they receive from you in the womb could make all the difference.

Influenza immunisation is available in New Zealand between mid to late March and 31 December, but immunisation is recommended before winter if possible.  If you become pregnant after winter and were not vaccinated earlier in the year you can still get vaccinated free until 31 December.

For more information about influenza immunisation, see the Fight Flu website.

Whooping cough (pertussis)

Being immunised against whooping cough while you are pregnant can protect your baby until they are old enough to be immunised, because your immunity can be passed on to your baby before they are born.

Whooping cough spreads very easily through coughing and sneezing. It can cause severe, prolonged coughing attacks and may lead to serious complications like pneumonia and brain damage. It is worse for babies under 1 year of age. They are often unable to feed or breathe properly so can become very ill, and may need to be cared for in hospital.

In New Zealand, babies are immunised against whooping cough at ages 6 weeks, 3 months and 5 months, then again at ages 4 and 11 years. They are not well protected from whooping cough until they have had their first three doses.

Unlike some other infectious diseases and immunisations, immunity to whooping cough decreases over time. This means that adults can catch whooping cough even if they have been immunised in the past or have previously had the disease. Many babies catch whooping cough from their older siblings or parents, often before they are old enough to be immunised.

Whooping cough immunisation is recommended and free for pregnant women between 28 and 38 weeks of pregnancy. Being immunised while you are pregnant can provide added protection for your baby. The whooping cough vaccine is safe for use in pregnancy.

The Ministry of Health recommends that other adults in close contact with babies should also be immunised against whooping cough. However, this is not free.

After pregnancy

It is safe to be immunised right after giving birth, even if you are breastfeeding. You can catch up on any immunisations you’ve missed out on during pregnancy – these immunisations are no longer free after you’ve given birth, but are still useful as they reduce the chance of you catching a disease and passing it on to your baby. You can also catch up on any other immunisations you need, such as MMR, that were not recommended while you were pregnant.

Childhood immunisation

Pregnancy is a good time to learn about childhood immunisations. Parents-to-be can learn more about childhood immunisation from the booklets “Childhood Immunisation” and “Immunise Your Child On Time”. It’s also a good time to think about choosing a doctor for your baby – babies should be enrolled in a general practice as soon as they are born, so that they can be ready to start their immunisations at 6 weeks. For more information, see Visiting a doctor.
