Are COVID-19 vaccines safe in pregnancy?

As the COVID-19 vaccination programme starts to be rolled out, many young women are hesitant to accept the vaccine, citing concerns about fertility.

Data on accidental pregnancies that occurred during the trials and, increasingly, outcomes in pregnant people who receive the vaccine can help these groups to make informed decisions. Reassuring data from accidental pregnancies that have occurred in the clinical trials of approved COVID-19 vaccines indicate that vaccination does not harm fertility or increase the rate of miscarriage.
