Get advice on the COVID-19 vaccine if you're pregnant, breastfeeding or trying for a baby.

If you’re pregnant, you can get a COVID-19 vaccine as part of Group 3 at any stage of your pregnancy. People in Group 3 are eligible to book their vaccinations now.

If you haven't made your appointments yet, you can call the COVID Vaccination Healthline on 0800 28 29 26 from 8am to 8pm, 7 days a week and someone will help you make your booking.

We encourage you to get the vaccine because while you’re pregnant you can become very sick if you get COVID-19.

Data from the large number of pregnant people already vaccinated globally shows that there are no additional safety concerns with giving COVID-19 vaccines.

Vaccinating during pregnancy may also help protect your baby as there’s evidence that infants can get antibodies to the virus through cord blood and breast milk. 

If you have any questions or concerns, discuss them with your healthcare professional

Timings with other vaccines if you’re pregnant

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.

No parts of the vaccine or the spike protein produced reach the ovaries or the testes.

How the Pfizer vaccine works


If you’re breastfeeding (as with all vaccines on the New Zealand Immunisation Schedule), there are no safety concerns about getting the Pfizer vaccine (Comirnaty).

When you're vaccinated, this can also provide some protection against COVID-19 for your baby through your breastmilk.
