COVID-19 vaccines in pregnancy and breastfeeding

Pregnant people are encouraged to be vaccinated against COVID-19 at any stage of pregnancy.


Vaccination against COVID-19 is recommended for pregnant people at any stage of pregnancy.

Vaccination is highly recommended during pregnancy, especially for those with underlying health conditions or high-risk pregnancies. The mRNA COVID-19 vaccine, Comirnaty™ (Pfizer/BioNTech, 30μg with purple cap) is available to anyone from 12 years of age. Two primary doses are given, ideally at least six weeks apart (minimum 21 days apart).

Booster doses

For those aged 18 years or over, a booster dose can be given from three months after the primary course, and if aged 16 to 17 years from six months after the primary course. Further doses (ie, second boosters) are not required at this stage for healthy people, including in pregnancy.


Millions of people have been given this vaccine while pregnant, and large-scale, international surveillance data (see below) indicate that there are no safety concerns with administering this COVID-19 vaccine in any stage of pregnancy. Vaccinating during pregnancy also offers temporary protection for newborns via passive transfer of antibody across the placenta and in breastmilk.

Discuss with health professional

Anyone with questions or concerns about receiving this vaccine in pregnancy is advised to discuss these with their health professional. Everyone has a right to make an informed decision about receiving the vaccine. The attached factsheet is designed to help support health professionals with these discussions.
