Vaccine advice if you are pregnant or breastfeeding

Learn about getting the COVID-19 vaccine if you are pregnant, breastfeeding or trying for a baby.

If you are pregnant

You can get the Pfizer vaccine at any stage of your pregnancy. 

The vaccine protects you as you are far less likely to fall seriously ill, and can also protect your baby. Evidence shows that babies can get antibodies through the placenta.

If you catch COVID-19 when you are pregnant, you are more likely to become very unwell. 

There is no evidence that the vaccine is associated with an increased risk of miscarriage during pregnancy. No additional safety concerns have been raised.
The Pfizer vaccine does not contain a live virus or any ingredients that are harmful to pregnant people or their babies.

Novavax vaccine

There is insufficient data on the use of Novavax in pregnant people, so Pfizer remains the preferred choice of vaccine for this group.


We recommend pregnant people who are eligible get the bivalent booster at any stage of pregnancy or during breastfeeding. It will need to be at least 6 months since you had a COVID-19 vaccine or a positive COVID-19 test.

You should discuss the timing of your booster with your midwife, obstetrician or doctor.

Get your vaccine booster



If you are breastfeeding

If you are breastfeeding, you can get the Pfizer vaccine at any time.

Studies show there are no additional safety concerns or issues with continuing to breastfeed after vaccination.

If you are vaccinated against COVID-19, there is evidence that you can provide extra protection for your baby through antibodies in your breastmilk.

If you are trying for a baby

If you are planning to get pregnant, you can get the Pfizer vaccine at any time. It will not affect your genes or fertility.
