Pregnancy, breastfeeding, fertility and COVID-19 vaccination
If you’re pregnant
If you’re pregnant, it’s important to get vaccinated to protect you and your baby.
You’re at higher risk of getting seriously ill from COVID-19 if you’re pregnant. If you get COVID-19 late in your pregnancy, your baby could also be at risk.
If you have not had a COVID-19 vaccine yet, it’s recommended to get your first 2 doses as soon as possible. You do not need to delay vaccination until after you have given birth.
It’s preferable for you to have the Pfizer/BioNTech or Moderna vaccine. This is because these vaccines have been more widely used during pregnancy in other countries and no safety concerns have been identified.
If you’ve already had the Oxford/AstraZeneca vaccine for your 1st dose and did not have any serious side effects, you should have it again for your 2nd dose.
If you had a 2nd dose of a COVID-19 vaccine at least 3 months ago, you can get a booster dose.
The vaccines cannot give you or your baby COVID-19.
If you’re breastfeeding
You cannot catch COVID-19 from the vaccines and cannot pass it to your baby through your breast milk.
If you’re breastfeeding, the vaccines you can have depends on your age:
- if you’re 40 or over, you can have any of the COVID-19 vaccines
- if you’re under 40 and do not have a health condition that increases your risk of getting seriously ill from COVID-19, it’s preferable for you to have the Pfizer/BioNTech or Moderna vaccine
The Pfizer/BioNTech or Moderna vaccines are preferable in people under 40 because of an extremely rare blood clotting problem linked to the Oxford/AstraZeneca vaccine.
Fertility and COVID-19 vaccination
There’s no evidence the COVID-19 vaccines have any effect on your chances of becoming pregnant.
There’s no need to avoid getting pregnant after being vaccinated.
