Covid-19 Vaccine - Frequently Asked Questions (FAQs)

Pregnancy, breastfeeding and fertility

You can have a COVID-19 vaccine if:

  • you're pregnant or think you might be
  • you're breastfeeding
  • you're trying for a baby

The vaccine cannot give you or your baby COVID-19.

If you're pregnant and have not had a vaccine yet, it's preferable for you to have the Pfizer/BioNTech or Moderna vaccine. This is because they've 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.

You can book your COVID-19 vaccination appointments online. If you're under 40, you'll only be shown appointments for the Pfizer/BioNTech or Moderna vaccine. If you're 40 or over, you'll be asked if you're pregnant to make sure you're only shown appointments for these vaccines.

At your appointment, you'll be able to discuss the benefits and potential risks of having a COVID-19 vaccine in pregnancy. This is so you can make an informed decision about having it. You can also speak to a GP or your maternity team for advice.

What about breastfeeding?

If you're breastfeeding, you can have any of the COVID-19 vaccines.

The benefits of breastfeeding are well-known. The JCVI has recommended that the vaccines can be received whilst breastfeeding. This is in line with recommendations from the USA and the World Health Organization.

Can the vaccines make you infertile (unable to have children)?

There's no evidence that the COVID-19 vaccines have any effect on your chances of becoming pregnant. There's no need to avoid pregnancy after vaccination.
