COVID-19 vaccination and pregnancy

The COVID-19 vaccines currently available in the UK have been shown to be effective and have a good safety record.

What is the advice about COVID-19 vaccines in pregnancy?

The Joint Committee on Vaccination and Immunisation (JCVI), an independent expert group, has advised that pregnant women should be offered COVID-19 vaccines at the same time as people of the same age or clinical risk group.

The vaccines have not yet been tested in clinical trials on pregnant or breastfeeding women. However, more than 110,000 pregnant women have been vaccinated with Pfizer or Moderna vaccines in the USA and no safety issues have been identified, so these two vaccines are preferred in pregnancy. Vaccination is very effective in preventing COVID-19 infection.

Anyone who has already started vaccination and is offered a second dose whilst pregnant should have a second dose with the same vaccine unless they had a serious side effect after the first dose.

Other vaccines, for example whooping cough and flu vaccines, have been given to millions of
pregnant women and found to be safe for them and their babies.

It is your choice whether to have the vaccine. For some pregnant women, the benefits of COVID-19 vaccination are particularly important.
