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.

AstraZeneca vaccine

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

Talk to your doctor about whether the AstraZeneca vaccine is suitable for you if you are pregnant or breastfeeding, or if you think you may be pregnant.

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.

Boosters

It is recommended that pregnant people receive a booster dose of the Pfizer vaccine to help protect them and their baby against the effects of COVID-19. The booster vaccine can be given at any stage of pregnancy.

If you are 18 or over, you can get your booster at least 3 months after your primary course (for most people, this is 2 doses). If you are 16 or 17, you can get a Pfizer booster at least 6 months after completing your primary course.

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

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.
