COVID-19 vaccines are safe if you are, or plan to become pregnant

You can safely get the COVID-19 vaccine before becoming pregnant or in any trimester of pregnancy. It is important that you stay up to date with your vaccines and receive all recommended doses of the COVID-19 vaccine.

Getting the vaccine during pregnancy will increase your protection against COVID-19 infection and reduce the risk of severe illness and complications related to COVID-19 infections in pregnancy. Studies have found that the antibodies your body develops following vaccination can be passed to your baby, which can help provide protection after birth.

Getting the COVID-19 vaccine while you’re pregnant, breastfeeding or trying to conceive is safe, effective and highly recommended by:

  • the Provincial Council for Maternal and Child Health (PCMCH)
  • Ontario Society of Obstetricians & Gynaecologists (OSOG)
  • the Society of Obstetricians and Gynecologists of Canada (SOGC)
  • National Advisory Committee on Immunization (NACI)
  • many other national and international organizations

Several studies have demonstrated that vaccination in pregnancy has no impact on:

  • pregnancy outcomes (including miscarriage, premature birth, fetal growth restriction and high blood pressure during pregnancy)
  • medical complications of pregnancy
  • maternal death

Read the Provincial Council for Maternal and Child Health’s information sheet on COVID19 vaccines to help you make an informed choice about the COVID-19 vaccine.

Risks related to COVID-19 during pregnancy

COVID-19 infection during pregnancy increases the risk of medical complications and death.

If you contract COVID-19 during your pregnancy, you are:footnote 1

  • more likely to be hospitalized
  • more likely to be admitted to the intensive care unit (ICU)
  • more likely to suffer from severe illness
  • more likely to require ventilation/life support breathing

In addition, COVID-19 infection in pregnancy significantly increases the risk of:

  • stillbirth
  • premature birth
  • high blood pressure
  • caesarean delivery
  • low birth weight

There is also an increased risk that the baby will need to be admitted to the neonatal intensive care.

COVID-19 vaccines are safe if you are, or plan to begin, breastfeeding

It is safe to get the COVID-19 vaccine while breastfeeding. There is no need to stop or delay breastfeeding after getting vaccinated. Studies show that receiving a COVID-19 vaccine while breastfeeding will not disrupt your breastfeeding and will not have an adverse impact on your baby.

Vaccines protect you from COVID-19 infection and help prevent you from passing it to your baby or other family members. If you get vaccinated while breastfeeding, the vaccine itself will not transfer into breastmilk, but studies suggest that the antibodies you produce following vaccination which may help protect your child from COVID-19.

COVID-19 vaccines and fertility

COVID-19 vaccines do not cause infertility.

In fact, getting all recommended doses of the COVID-19 vaccine before you conceive will help protect you and your future baby from the risk of COVID-19 in pregnancy.
