COVID-19 vaccination and pregnancy

Being pregnant (hapū) during the COVID-19 pandemic has made many people anxious about their own health and that of their unborn or newborn baby. Here is some information about managing your COVID vaccinations when you are planning a pregnancy, pregnant or breastfeeding.

If you are pregnant, aged 18 years and older, it is recommended you receive a booster of the Pfizer vaccine to help protect you and your baby against the effects of COVID-19. The booster can be given at any stage of pregnancy. You can receive your booster dose at least 3 months after your second dose. You should discuss the timing of a booster with your midwife, obstetrician or general practitioner.

Book your COVID-19 vaccination now

If you are pregnant (hapū), or planning a pregnancy, it is important to have the COVID-19 vaccine. Studies have shown this is safe and better for you and your baby. If you get COVID-19 while you’re pregnant you can become very sick.

If you’re pregnant, you can get a COVID-19 vaccine at any stage of your pregnancy. 

If you haven't made your appointments yet, you can:

  • ask your GP clinic if they are providing the COVID-19 vaccine 
  • book online at Book My Vaccine
  • book by phone – call the COVID Vaccination Healthline on 0800 28 29 26 (8am to 8pm, 7 days a week).

Pfizer (Comirnaty) vaccine is the preferred vaccine for use during pregnancy 

Data from the large number of pregnant people already vaccinated globally shows that there are no additional safety concerns with giving the Pfizer (Comirnaty) vaccine. Vaccinating during pregnancy may also help protect your baby. There is evidence that infants can get antibodies to the virus through umbilical cord blood and through breast milk.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, check with your health care provider about the use of the AstraZeneca vaccineThere is limited information available on the use of the AstraZeneca vaccine with pregnant women so the Pfizer (Comirnaty) vaccine remains the vaccine of choice if you are pregnant. 

If you have any questions or concerns, discuss them with your health professional. Read more about COVID-19 vaccination, pregnancy, lactation and breastfeeding from the Immunisation Advisory Centre. Karawhiua also has answers to FAQs about the COVID-19 vaccine, especially for Māori. 

Booster doses 

If you are pregnant, aged 18 years and older, it is recommended you receive a booster of the Pfizer vaccine to help protect you and your baby against the effects of COVID-19. The booster can be given at any stage of pregnancy, at least 3 months after your second dose (effective from 4 February 2022). Read more about COVID-19 vaccine booster doses.

You should discuss the timing of a booster with your midwife, obstetrician or general practitioner.   

Get the usual vaccinations

You should also get vaccinated against the flu and whooping cough (pertussis) because the risk of these is just as high as ever. Getting vaccinated during pregnancy protects you and your newborn baby against these serious infections. 

You can get the influenza vaccine and COVID-19 vaccine at any stage of pregnancy and whooping cough vaccine from 16 weeks of pregnancy. They can be given at the same time or separately. Read more about pregnancy and immunisations.

It is crucial that babies and infants get their regular vaccinations as outlined in the National Immunisation Programme. These are usually given at 6 weeks, 3 months, 5 months and 15 months. These vaccinations protect against a range of diseases, including whooping cough and measles, the risk of which is as high as ever. Read more about childhood immunisation

Follow advice to prevent COVID-19 

Practising good hand and cough hygiene and following the current alert level advice are the best ways to protect you and your baby from COVID-19. Also keep looking after yourself during your pregnancy, both physically and mentally. Read more about pregnancy and wellbeing

Make contact early 

Contact your lead maternity carer (LMC) or midwife early in your pregnancy, so you can be assessed for risk factors and referred for other appointments, if needed.

Continue to have regular check-ups

Keep getting regular check-ups during your pregnancy, to monitor the health of yourself and your baby. Talk to your LMC as to how this will be done at different levels. They may recommend less frequent visits if you and your baby are healthy, or they might be able to offer telehealth consultations (by video call) for some of your appointments. Read more about telehealth.

Be assured that hospitals are safe 

If you are asked to go to hospital for care or assessment, be reassured that it is safe to do so.

  • Check with your LMC that they have safe sleep devices available in the maternity unit if you need one. 
  • When you are discharged from hospital, make sure your maternity team has given you advice on how to tell if you are getting sick, who to contact if you do get sick and how to contact them.

Breastfeed your baby

It's safe to breastfeed your baby – there is no evidence of transmission of the COVID-19 virus in breast milk. Exclusive breastfeeding offers the best protection for babies, so if your baby is less than 6 months old, aim to only breastfeed.

It is also safe to have the COVID-19 Pfizer vaccine while you are breastfeeding. When you're vaccinated, this can also provide some protection against COVID-19 for your baby through your breastmilk.

Trying for a baby

If you’re planning a pregnancy, you can receive the Pfizer vaccine (Comirnaty). The Pfizer vaccine will not affect your genes or fertility. The mRNA from the vaccine does not enter the nucleus of any cells, which is where your DNA is.

Use reliable information sources

Because COVID-19 is a new disease, information about its effects on pregnancy and breastfeeding is still evolving. There is much information on the internet, but not all sources are reliable. 

The following are trustworthy organisations that are constantly reviewing the current situation and updating their websites with information about pregnancy, delivery and breastfeeding during the COVID-19 pandemic. If you have any questions, talk to your LMC.
